A Complete Guide To Sailing In A Storm

Sailing in a storm can be a challenging experience but with the right preparation and techniques, it can be navigated safely in most instances.

While it's best to avoid storms when sailing, there are times when storms cannot be avoided.

To sail in a storm:

• Prepare the sailboat for a storm
• Monitor the weather conditions
• Adjust the sailboat to stabilize the vessel in the storm
• Maintain communication with the coast guard

The number one priority when sailing in a storm is safely navigating through the water during these bad weather conditions.

1. Prepare The Sailboat For A Storm

The first step of sailing in a storm is to prepare the sailboat for storm weather conditions.

To prepare a sailboat for a storm:

• Check the rigging & sails : Assess the rigging and sails overall condition. Ensure they are in full working order with no issues with maneuverability or rips in the sails. There should be a storm sail onboard too in preparation for sailing in the storm
• Ensure safety equipment is onboard : Ensure there are liferafts, life jackets for everyone onboard, life buoys, heaving lines, sailing jackets, flashlights, flares, VHF radios, chartplotter/GPS, first aid kits, and fire extinguishers
• Remove the boat canvas/bimini top : In preparation for sailing in a storm, remove the boat canvas/bimini top to prevent it from getting damaged or destroyed or causing injury to passengers onboard ‍
• Ensure loose items are tied down : Any loose items like lines on the deck should be tied down and secured before sailing in a storm. Loose items can become dislodged and damaged or cause injury to passengers onboard if they are not secured during a storm
• Ensure the sailboat's engine is in great condition : Ensure the sailboat's motor is in perfect condition with sufficient oil and fuel to operate during the storm

Preparing the sailboat for a storm will take approximately 30 minutes to complete. This timeframe will vary depending on the size of the vessel and the amount of equipment needed to be purchased and installed onboard.

In preparing for sailing in a storm, there is certain sailboat equipment needed. The equipment needed for sailing in a storm includes a storm sail, heaving lines, sailing jackets, life jackets, life buoys, liferafts, first aid kit, Chartplotter/GPS, fire extinguishers, VHF radio, and flares.

The benefits of preparing the sailboat for a storm are a sailor will be prepared for any issues caused by the storm and a sailor will have the necessary safety equipment to help keep everyone onboard safe during the storm.

One downside of preparing the sailboat for a storm is it can be costly (over $500) especially if the sailor does not have all the right equipment needed to withstand the stormy weather. However, this is a small downside.

2. Monitor The Weather Conditions

The second step of sailing in a storm is to monitor the weather conditions regularly.

To monitor the weather conditions:

• Connect to the VHF radio weather channel : Connect to channel 16 on the VHF radio as this channel provides storm warnings and urgent marine information for boaters
• Use a chartplotter : Modern chartplotters will have marine weather data for boaters to monitor the weather conditions and check windspeeds, rainfall levels, wave height and other relevant marine weather data
• Check a marine weather forecast provider website : If you have internet access on the sailing trip, connect to a marine weather provider for marine weather forecast information in your area

In sailing, weather conditions are considered a storm when the wind speed is 28 knots or higher and the wave heights are 8ft or higher. Other characteristics of stormy weather when sailing is poor visibility with visibility ranges of under half a mile (0.8km or less) and heavy rain with a precipitation rate of at least 0.1 inches (2.5 millimeters) per hour.

It can take approximately 3 to 6 hours for a storm to fully develop when sailing. However, for larger storms, it can take over 2 days for the storm to fully develop.

Monitoring the weather should be done every 20 minutes when sailing in a storm to get up-to-date information on potential nearby locations with better weather to sail to.

The benefit of regularly monitoring the weather conditions is a sailor will be more prepared for the weather that lies ahead and the sailor will be able to make adjustments to their sailing route to help avoid the bad weather.

3. Adjust The Sailboat To Stabilize The Vessel

The third step of sailing in a storm is to adjust the sailboat to stabilize the vessel.

When sailing through the storm, reef the sails to reduce the stress and load on the mast and sails, attach the storm sails, turn the vessel until the wave and wind direction are blowing from the stern of the sailboat, i.e. the wind is blowing downwind. Carefully tack the sailboat slowly until the boat is in the downwind position. Pointing the sailboat downwind is not recommended if the sailboat is near land as it could cause the boat to run into the land.

Alternatively, if the storm is very bad, sailors can perform a "heaving to" storm sailing maneuver.

To perform the heave-to storm sailing maneuver:

• Turn the bow of the boat into the wind : This involves turning the sailboat so that the bow faces into the wind. This will cause the boat to lose forward momentum and begin to drift backward
• Adjust the sails : Depending on the size and configuration of your boat, you may need to adjust the sails in different ways. In general, you will want to position the sails so that they are catching less wind and are working against each other. This will help to slow the boat's drift and keep it from moving too quickly
• Adjust the rudder : You may need to adjust the rudder to keep the boat from turning too far or too fast. In general, you will want to angle the rudder slightly to one side to counteract the wind and keep the boat on a stable course
• Monitor the boat's drift : Once you have heaved-to, you will need to monitor the boat's drift and make small adjustments as needed to maintain your position. This may involve adjusting the sails, rudder, or other factors as conditions change

The heaving to maneuver is used to reduce a sailboat's speed and maintain a stationary position. This is often done in rough weather to provide the crew with a stable platform to work from or to wait out a storm.

This sailing maneuver will adjust the sailboat and should stabilize the vessel in the storm.

The benefits of adjusting the sailboat position in a storm are it will help to stabilize the boat, it will improve safety, it will reduce the crew's fatigue as the crew will not be operating with a boat at higher speeds, it will help maintain control of the sailboat, and it will reduce stress on the sailboat and the rigging system.

Depending on the size of the sailboat, how bad the weather conditions are, and a sailor's experience level, adjusting the sailboat to stabilize it in the storm should take approximately 10 minutes to complete.

4. Maintain Communication With The Coast Guard

The fourth step of sailing in a storm is to maintain communication with the coast guard.

This is particularly important if the storm is over Beaufort Force 7 when sailing is much harder.

To maintain communication with the coast guard during a storm:

• Understand the important VHF channels : During sailing in a storm, be aware of VHF international channel 16 (156.800 MHz) which is for sending distress signals
• Ensure there are coast guard contact details on your phone : Put the local coast guard contact details into your phone. These contact details are not substitutes for using the VHF channel 16 distress signal or dialing 911. These contact details should only be contacted if all else fails

Contacting the coast guard takes less than 1 minute to complete and they are fast to respond in case of an emergency caused by the storm.

The benefits of maintaining communication with the coast guard during a storm are it will help improve safety, the coast guard will be able to provide real-time alerts, and it will provide navigation assistance as the coast guard has access to the latest navigation technology and can guide you through the storm's hazardous areas such as shallow waters or areas with a strong current.

Frequently Asked Questions About Sailing In A Storm

Below are the most commonly asked questions about sailing in a storm.

What Should You Do If You're Caught Sailing In A Storm With Your Boat?

if you're caught sailing in a storm with your boat, you should reef the sails, attach the storm sails and tack the vessel slowly until the wave and wind direction are blowing from the stern of the sailboat.

Should You Drop An Anchor When Sailing In A Storm?

Dropping an anchor can be a useful technique to help keep a boat steady during a storm. However, whether or not to drop an anchor depends on a variety of factors including the size and type of the boat, the severity of the storm, the water depth, and the type of bottom (i.e., mud, sand, or rock).

If you are in a smaller boat that is being pushed around by the waves, dropping an anchor can help keep the boat oriented in a particular direction, reducing the boat's drift. Additionally, it can help reduce the risk of capsizing or being thrown onto a rocky shore.

However, if the storm is very severe with high winds and waves, the anchor may not be enough to hold the boat in place, and it may put undue stress on the anchor and the boat's attachment points. In such a case, it is usually better to try to navigate to a sheltered area or to deploy sea anchors that can help reduce the boat's drift.

It is also essential to be careful when anchoring in a storm as it can be challenging to set the anchor correctly and the wind and waves can cause the anchor to drag.

Is It Safe To Sail In A Storm?

Sailing in a storm should be avoided due to the lack of safety. However, experienced sailors can sail in storms up to Beaufort Force 7 if required. Beaufort Force 8 and higher storms are extremely dangerous to sail in and should be avoided at all costs.

How Do You Improve Safety When Sailing In A Storm?

To improve safety when sailing in a storm, wear a life jacket, hook everyone onboard up to a safety line or harness so they don't fall overboard, reef the sail to improve the sailboat's stability, and understand where all the safety equipment is onboard and how to operate it in case of an emergency.

What Type Of Storm Should Not Be Sailed In?

A sailor should not sail in any storm but especially a storm from Beaufort Force 8 to Beaufort Force 12 as it is considered to be too dangerous.

Can You Sail Through A Hurricane?

While sailors have successfully sailed through hurricanes in the past, sailing through a hurricane should be avoided at all costs. Sailing in hurricane weather is too dangerous and could result in loss of life.

What Are The Benefits Of Sailing In A Storm?

The benefits of sailing in a storm are:

• Improves sailing skills : Sailing in a storm will force sailors to improve their sailing skills and increase their ability to handle rough seas
• Exciting experience : For some sailors, the thrill of navigating through a storm can be an exhilarating experience that they enjoy. The adrenaline rush and sense of accomplishment of successfully sailing through a storm can be incredibly rewarding
• Greater appreciation for the power of nature : Sailing in a storm can provide a unique perspective on the power of nature. It can be humbling and awe-inspiring to witness the raw force of the wind and waves and this can lead to a greater appreciation for the natural world

It's important to note that these potential benefits should never come at the expense of safety. For the majority of sailors, it is smarter to avoid sailing in a storm and instead wait for the bad weather to pass.

What Are The Risks Of Sailing In A Storm?

The risks of sailing in a storm are:

• Boat sinking/capsizing : With high winds over 28 knots and waves and swells at heights over 8ft, there is a risk of the sailboat capsizing and sinking
• People drowning : High winds and high waves during a storm can cause people onboard to fall overboard and drown
• Loss of communication : Bad storm weather can cause the sailboat's communication system to stop working making it much harder to signal for help if needed
• Boat damage : Storm weather can damage the boat including the sails, mast, rigging system, lines, Bimini top, etc.
• Poor visibility : Sea spray, large waves over 8ft, and heavy winds over 28 knots can reduce the visibility to under 500 meters in some instances making it difficult for navigation
• People being injured : People onboard can get injured due to the increase and sharp movements caused by the storm

What Should Be Avoided When Sailing In A Storm?

When sailing in a storm, avoid:

• Getting caught sailing in the storm in the first place : Ideally, a sailor should avoid sailing in the storm in the first place by checking the weather radar and instead wait for the weather to clear before continuing their sailing trip
• Increasing the sail area : Increasing the sail area in a storm should be avoided as it can cause the sailboat to become more unstable and increase the risk of capsizing
• Not wearing a life jacket : Life jackets should be worn at all times when sailing but especially during a storm. Avoid not wearing a life jacket in a storm as there is no protection if someone falls overboard
• Not wearing the appropriate gear to stay dry : Sailors should avoid not wearing the appropriate foul weather gear to stay dry when sailing in a storm
• Not connecting the crew to safety lines/harness : When sailing in a storm, all crew on the boat deck should be
• Not understanding the safety equipment : Sailors should avoid not understanding the safety equipment onboard

How Do You Avoid Sailing In A Storm?

To avoid sailing in a storm, check the weather forecast regularly when going on a sailing trip to know when and where not to sail as the weather gets worse in these areas. If a sailing trip involves passing through a storm, wait in an area where there is no storm until the weather clears up in the storm area before continuing on the voyage.

What Are The Best Sailboats For Sailing In A Storm?

The best sailboats for sailing in a storm are the Nordic 40, Hallberg-Rassy 48, and the Outremer 55.

What Are The Worst Sailboats For Sailing In A Storm?

The worst sailboats for sailing in a storm are sailing dinghies as they offer little protection from the dangers of stormy weather.

What Is The Best Sized Sailboat For Sailing In A Storm?

The best-sized sailboats to sail in a storm are sailboats sized 30ft. and longer.

What Is The Worst Sized Sailboat For Sailing In A Storm?

The worst-sized sailboats to sail in a storm are sailboats sized under 30ft. as it is more difficult to handle rough weather and choppy waves in these boats.

HOW TO SAIL SAFELY THROUGH A STORM

Tips and tricks to help you get home safe.

Compared to the quick response and sudden nature of a squall , sailing through a storm in open water is an endurance contest. In addition to big wind, you’ll have to deal with big waves and crew fatigue.

Sailing in Waves

Sailing in big waves is a test of seamanship and steering, which is why you should put your best driver on the helm. Experienced dinghy sailors often are very good at heavy air steering, because they see “survival” weather more often than most cruisers.

Avoid sailing on a reach across tall breaking waves; they can roll a boat over. When sailing close-hauled in waves, aim toward flat spots while keeping speed up so you can steer. To reduce the chance of a wave washing across the deck, tack in relatively smooth water. A cubic foot of water weighs 64 pounds, so a wave can bring many hundreds of pounds of water across the deck.

Sailing on a run or broad reach in big waves is exhilarating, but be careful not to broach and bring the boat beam-to a breaker. Rig a preventer to hold the boom out.

Storm Sails

If reefing isn’t enough to reduce power, it’s time to dig out your storm sails — the storm trysail and storm jib. They may seem tiny, but since wind force rises exponentially, they’re the right size for a really big blow. Storm trysails are usually trimmed to the rail, but some modern ones are set on the boom. The storm jib should be set just forward of the mast to keep the sail plan’s center of effort near the boat’s center of lateral resistance. This helps keep the boat in balance.

Storm Strategy

The first decision before an approaching storm is the toughest: Run for cover, or head out to open water for sea room? With modern forecasting, a true storm will rarely arrive unannounced, but as you venture further offshore the chances of being caught out increase. While running for cover would seem the preferred choice, the danger lies in being caught in the storm, close to shore, with no room to maneuver or run off.

Two classic storm strategies are to try to keep away from land so you’re not blown up on shore, and to sail away from the storm’s path — especially its “dangerous semicircle,” which is its right side as it advances.

Storm Tactics

Storm tactics help you handle a storm once you’re in it. There are several proven choices, all of which aim to reduce the strain and motion by pointing one of the boat’s ends (either bow or stern) toward the waves. No one tactic will work best for all boats in all conditions.

Sail under storm jib and deeply reefed mainsail or storm trysail. This approach provides the most control. Sails give you the power to steer and control your boat in the waves.

Run before the storm with the stern toward the waves, perhaps towing a drogue to slow the boat. This tactic requires a lot of sea room, and the boat must be steered actively. Another concern is that you will remain in front of an approaching storm, rather than sailing out of its path.

Heave-to on a close reach with the jib trimmed to windward. Heaving-to can be an excellent heavy weather tactic, though some boats fare better than others.

Deploy a sea anchor while hove-to or under bare poles. A sea anchor is a small parachute set at the end of a line off the bow. A sea anchor helps keep the bow up into the waves so the boat won’t end up beam to the seas. One concern is the load on the rudder as waves push the boat aft.

Another alternative is lying ahull, simply sitting with sails down. This passive alternative is less reliable than the other tactics, as you lose the ability to control your angle to the waves and may end up beam to the seas. Furthermore, the motion of the boat rolling in the waves without the benefit of sails can be debilitating.

How to Heave-To

Wouldn’t it be great if, during a heavy air sail, you could just take a break, and relax for a bit? Imagine a short respite from the relentless pitching and pounding: a chance to rest, take a meal, or check over the boat in relative tranquility. Well, you can. The lost art of heaving-to allows you to “park” in open water.

To heave-to, trim the jib aback (i.e., to the wrong side), trim the main in hard, and lash the helm so the boat will head up once it gains steerageway. As the jib tries to push the bow down, the bow turns off the wind and the main fills, moving the boat forward. Once the boat begins to make headway, the lashed helm turns the boat toward the wind again. As the main goes soft the jib once again takes over, pushing the bow down. The main refills, and the rudder pushes the bow into the wind again.

The boat won’t actually stop. It will lie about 60 degrees off the wind, sailing at 1 or 2 knots, and making significant leeway (sliding to leeward). The motion will be much less than under sail, and dramatically more stable and pleasant than dropping all sails and lying ahull. You will also be using up less sea room than if you run before the storm at great speed.

Achieving this balance will require some fine tuning, depending on the wind strength, your boat design, and the sails you are flying. Also, fin-keeled boats do not heave to as well as more traditional designs.

In storm seas, some boats will require a sea anchor off the bow to help hold the boat up into the waves while hove-to.

Alternate Storm Strategy: Don’t Go

If conditions are wrong, or are forecast to worsen, don’t go. If you can avoid the storm, then do so.

If you’re at home, stay there. If you’re mid-cruise, button up the boat, make sure your anchor or mooring or dock lines are secure, and then read a book or play cards. Relax. Enjoy the time with your shipmates. Study the pile of Owners’ Manuals you’ve accumulated with each piece of new gear. Tinker with boat projects.

Put some soup on the stove, and check on deck every so often to make sure the boat is secure. Shake your head as you return below, and remark, “My oh my, is it nasty out there.”

If your boat is threatened by a tropical storm or hurricane, strip all excess gear from the deck, double up all docking or mooring lines, protect those lines from chafe, and get off. Don’t risk your life to save your boat.

Misery and Danger

Although everyone will remember it differently years later, a long, wet, cold sail through a storm can be miserable. As the skipper, you need to make the best of it: watch over your crew, offer relief or help to those who need it, and speak a few words of encouragement to all. “This is miserable, but it will end.”

Take the time to marvel at the forces of nature, and at your ability to carry on in the midst of the storm. Few people get to experience the full fury of a storm. It may not be pleasant, but it is memorable.

While misery and discomfort can eventually lead to fatigue, diminished performance, and even danger, do not mistake one for the other. Distinguish in your own mind the difference between misery and danger. Don’t attempt a dangerous harbor entrance to escape misery; that would compromise the safety of the boat and crew, just to avoid a little discomfort.

Conclusion: Your Sailboat In A Storm

The key to sailing in a storm is being prepared. We knew this, and yet the first time we got caught in big weather we weren’t prepared at all, and we felt really stupid for it.

Don’t be us!

You should be prepared for bad weather every single time you leave the safety of the harbour. You never know when the weather will change on you and you should always know exactly what you’ll do when that happens.

Here are a few things you can do while the weather is calm to help you prepare for the worst case scenario.

The Science of Storms

Understanding the dynamics of storms, including their formation, movement, and intensification, will enable you to make informed decisions before you even leave the anchorage.

You don’t need to become a weather expert, but you should learn how to read the weather using various sailing forecasts, and be aware of all the different tools available to you.

Another key skill is knowing weather patterns in the specific area you’re sailing in. Ask local fishermen and sailors how to spot bad weather and ‘read the skies’ as well as the forecasts.

In Greece, for example, you can predict the onset of the Meltemi winds by watching for dew on the deck. You can also learn a lot from watching the fishing boats. If they suddenly flock to port it’s a sure sign there will be bad weather on the way!

Preparing Your Sailboat

Properly equipping your sailboat before setting sail is crucial for handling a storm.

We always do pre-sail checks before setting off on a passage, but after days of sailing in calm weather, it’s easy to get complacent. Especially when there’s a favourable forecast.

This was our biggest mistake in one of the big storms we got stuck in. We usually stow our paddleboards, but we were forecast great weather and decided to tie them down on deck instead. We lost one over the side after a huge wave ripped it out of the lines and washed it overboard. Luckily it wasn’t anything more important.

You need to check for things like working bilge pumps, check your marine batteries and that you have a healthy running engine, do regular rigging inspections, check your sailboat mast , and check the quality of your lines and sails. These sorts of things should all be part of your going-to-sea checklist and are easy to keep on top of because they’re so vital.

The things that are easier to forget, but just as important, are things like ensuring hatches and portholes are properly closed and fastened, cupboards are all latched, and everything is stowed away safely.

I read a really interesting account of a couple who got caught in a severe storm. When a wave hit their top-loading fridge flew open spilling the contents everywhere. Eggs all over the floor made it impossible to move around below deck safely, and serious injuries occurred.

Think of everything, every time! And make it part of your daily routine.

Safety Equipment

Alongside your regular boat checks should be regular safety equipment checks.

To begin with, you should make sure you have all the safety equipment onboard before heading out to sea. This includes things like lifejackets , tethers, jackstays, liferafts, EPIRBS, grab bags, flares, etc.

You should make sure you inspect safety equipment regularly. Keep on top of things like recharging lifejackets and getting liferafts inspected regularly. Make sure your life sling is free to run. Make sure you have a sailing knife somewhere handy.

You should also know how to use your safety equipment and regularly practice your man overboard drills.

S eamanship Techniques

Once you find yourself sailing through a storm, it’s vital to know how to handle your sailboat effectively. This requires knowing your boat and how it handles best and will take some practice.

You can practice in calm weather, you don’t need to be in the middle of a storm to figure out certain techniques (and you shouldn’t be!) Make storm tactic practice a regular part of your sailing routine, and make sure the crew is aware of what you’ll do if heavy weather creeps up on you.

We’ll take a more in-depth look at different storm tactics below!

Crew Safety and Communication

In a storm, the safety of you and your crew is paramount. Before you head out to sea you should always brief your crew so they know all the major systems onboard. Imagine you got knocked unconscious – what would they need to know to get you and the boat to safety?

They should all have appropriate safety equipment and know your rules on using it. It’s important they trust and respect you as the skipper, because if things get tough out there you’ll want them to follow your orders.

You need to make sure they are comfortable with the way you run your ship. It’s easy to bark orders that are difficult to understand when you’re under pressure, so it’s up to you as captain to practice good communication skills onboard.

Mental Preparedness

Sailing in stormy conditions can be mentally and physically demanding. Often the sailboat is fine in a storm, but the people onboard fall apart long before the boat will.

Storms bring rough seas, and rough seas bring seasickness, anxiety, fear, and panic. You need to know what you’ll do if one or more of your crew becomes able to play their role.

When we got caught in big seas on a passage from Croatia to Greece Adam was flat on his back with seasickness for most of the journey. Luckily I knew the boat well enough to single-hand for large chunks of time, and he knew how to handle his seasickness well enough that he could take short watches while I slept.

Being prepared for this mentally by knowing the boat and our own capabilities played a huge role in the fact we managed to get the boat to safety.

Storm Tactics

Make sure you carefully think through your storm tactics and share them with your crew before you head out to sea. Here are a few storm tactics that might be worth practicing on calmer sails, so you know exactly what to do when bad weather hits.

This seems like a daft one to put first, but hypothermia will kill you much quicker than a storm. Luckily when we got really caught out it was summer and the temperatures were high, but even so we very quickly realised how stupid we were for heading out without decent sailing foulies.

The night was a very cold, very wet one. We survived it, but we vowed we would have all the proper kit before ever heading out to sea again.

As a minimum, make sure you have easily accessible layers (you do not want to be rummaging around below in a bad sea state), a decent sailing jacket and waterproof trousers, non-skid shoes, or even better, sailing boots .

For colder climates, it’s wise to consider a sailing drysuit .

Before the storm picks up make sure you’re kitted out. One rogue wave that sneaks overboard before you have your waterproof layers on could be a real killer.

One of the first steps to take in any sailboat when the weather picks up is to reef the sails . It’s unlikely that a storm will go from 0 knots to 60 (though obviously this can happen!) so as the wind builds, so should the reefs in your sails.

Reefing is simply making the sail area smaller. Different boats will have different points at which they need to reef, and your sail set up will be different too. Offshore sailors often have three reefing points in their sails so they can make them as small as possible.

Reefing the mainsail is hardest. You might need to go up to the mast to drop the sail a portion of the way down before trimming the sail again.

Foresails like jibs are often on furlers, and can be furled away as small as you like. You’ll just want to be careful the sails are balanced so you don’t have to work too hard on the helm.

Once your sailboat is fully reefed and still struggling in the wind speeds you’re getting, it’s time to consider putting up your storm sail.

Your storm sail is a vital piece of safety gear on board.

Storm sails are specialized sails designed to be used in extreme weather conditions, particularly during storms or heavy winds. They are smaller, stronger, and more heavily reinforced than regular sails, allowing a sailboat to maintain control and reduce the risk of damage or capsize in challenging weather.

Here are the main types of storm sails commonly used:

• Storm Jib: The storm jib is a small headsail that is hanked or attached to the forestay closer to the deck. It is typically made of heavy-duty fabric and has a high-cut clew (lower corner) to prevent interference with the deck or waves. The storm jib is used when the wind becomes too strong for the regular headsail, providing better control and stability.
• Storm Trisail: A storm trisail is a triangular sail that is hoisted on a separate mast track, usually on the aft side of the mast. It is set independently from the mainsail and provides an alternative to using the main in extreme conditions. The storm trisail is typically made of heavy-duty fabric and has a shorter luff (leading edge) than the regular mainsail.
• Storm Staysail: A storm staysail is a small sail set between the mast and the forestay. It is usually hanked or attached to a removable stay or a dedicated inner forestay. The storm staysail provides additional stability and control when conditions are too severe for other sails. It is typically made of heavy-duty fabric and has a high-cut clew to avoid interference.

Storm sails are designed to handle high winds and heavy seas, allowing a sailboat to maintain some degree of maneuverability and control.

They are usually constructed from stronger and more durable materials, such as heavy Dacron or woven synthetic fibers, and often feature reinforced stitching and webbing to withstand the increased loads and forces experienced in stormy conditions.

It’s important to note that deploying storm sails should be done in advance of extreme weather and in accordance with the manufacturer’s recommendations. P

roper training and experience are crucial for effectively using storm sails, as they require careful sail handling and adjustments to maintain the boat’s balance and stability.

Heaving to in a sailboat is a valuable technique used to effectively manage challenging weather conditions, especially in a storm. It allows you to temporarily pause your boat’s forward progress, stabilize it, and create a safe and controlled environment.

It’s basically putting the brakes on your sailboat.

Here’s a step-by-step guide on how to heave to in a sailboat, but bear in mind that every sailboat is slightly different so you will need to play around a bit with your individual boat in calm weather to work out what works best for your boat and crew.

• Assess the conditions: Determine if heaving to is the appropriate strategy for the current situation. Heaving to is most effective in moderate to heavy winds and moderate seas. If conditions are extreme or dangerous, it may be safer to consider alternative tactics or seek shelter.
• Prepare the boat: Before executing the maneuver, prepare your sailboat by reefing the sails. Reduce the sail area to a level that provides sufficient control while minimizing the boat’s forward motion. Typically, this involves reefing the mainsail by lowering it partially or completely and adjusting the headsail accordingly.
• Decide on the tack: Choose the tack to heave to based on factors such as wind direction, sea state, and the boat’s handling characteristics. The tack selection can vary depending on the boat’s design and personal preference. In general, choose the tack that allows the boat to face into the wind with the mainsail backed.
• Head up into the wind: Turn the boat into the wind by steering toward the chosen tack. This maneuver will cause the boat’s forward momentum to decrease as it approaches a position directly facing into the wind.
• Backwind the headsail: Once the boat is pointing into the wind, backwind the headsail to help balance the forces acting on the boat. To do this, ease the headsail sheet, allowing it to fill on the opposite side of the boat from its normal position. This action will counteract the forward drive and assist in keeping the boat stationary or with minimal drift.
• Adjust the rudder: Set the rudder position to maintain balance and control. Depending on the boat’s design and behavior, you may need to experiment with the rudder angle to achieve the desired heaving to effect. In some cases, you may need to lock the helm in position or use a tiller-tamer device to maintain the rudder angle.
• Fine-tune and monitor: Once in the hove-to position, make any necessary adjustments to the sails, rudder, and other controls to achieve a stable and comfortable balance. Monitor the boat’s behavior, making sure it only drifts very slowly.

The boat won’t actually stop. It will typically lie about 60 degrees off the wind, sailing at around 1 knot, and sliding to leeward.

The motion will be much less than under sail, and dramatically more stable and pleasant than dropping all sails and lying ahull. You will also be using up less sea room than if you run before the storm at great speed.

Heaving to provides a stable platform in which you can wait out a storm, take a break, or perform necessary tasks while minimizing the boat’s motion and maintaining control.

It’s important to note that the specific technique may vary depending on your sailboat’s design and the prevailing conditions, so always consult your sailboat’s manual or seek guidance from experienced sailors for your particular boat type.

Drogue Or Sea Anchor

A drogue or sea anchor is a device used in boating and sailing to provide stability and control in heavy weather or when facing strong currents, winds or waves. Its primary purpose is to reduce a boat’s drift and help maintain a more stable position relative to wind and waves.

Here are the key points and benefits of using a drogue or sea anchor:

• Reducing drift: In stormy conditions, strong winds and currents can cause a boat to drift uncontrollably, potentially leading to loss of steering and stability. By deploying a drogue or sea anchor, the device creates drag in the water, effectively slowing down the boat’s drift and providing a steadier position.
• Enhancing stability: When a drogue or sea anchor is deployed from the stern of a boat, it helps to stabilize the vessel by reducing yawing (side-to-side motion) and rolling caused by wind and waves. This stability can be crucial for crew safety, preventing excessive motion and reducing the risk of capsizing or broaching.
• Improving safety: In extreme conditions, using a drogue or sea anchor can significantly improve overall safety on board. It reduces the risk of broaching (where the boat is turned broadside to the waves) and pitch-poling (when the boat’s bow is driven under a breaking wave), both of which can lead to dangerous situations. The device helps to create a controlled environment, minimizing the chances of damage, injuries, or loss of control.

We have never needed to use our drogue, but we have been close even in the Mediterranean, so it’s good to be prepared.

If you don’t have one but you find yourself in storm conditions where you need one, then doing something like hanging lines from the stern of the boat can actually make quite a big difference,

Sailing in big waves is not for the faint of heart, but if you trust your boat and your captain it can be an exciting experience!

One of the hardest things about sailing in big waves is steering. Your most experienced helmsman should be on the helm when the weather gets rough. Reading the waves is vital.

One of the key things to remember is that you must not sail on a reach across tall, breaking waves. If they hit you at the right angle and at the right time there is every possibility they could roll the boat. It’s a good idea to be familiar with capsize ratio and what this could mean for you.

If you have to sail upwind (we would do everything possible to avoid this!) then aim towards the parts of the wave that aren’t breaking. There is huge force in breaking waves and you want to avoid them if you can. Or you might lose your paddleboard!

Tack in smooth water if possible, and try to keep the speed up as you’re going over the waves so you don’t lose steerage.

The best option is to sail on a broad reach. Even though we knew this we still attempted to sail upwind to reach our destination and it simply wasn’t possible in our older, heavy displacement boat. Instead, we turned downwind and ran all the way to Italy. It wasn’t where we needed to go (far from it) but as soon as we turned downwind the ride got a whole lot more comfortable and manageable.

When running downwind you will just need to be careful you don’t broach and turn the boat beam on to a wave. This might mean you need to deploy a drogue to slow the boat down.

Post-Storm Assessment

After the storm has passed, it’s essential to assess any damage and evaluate your performance. Someone we know sailed through the night in a storm and when he reached port he carried out a rigging inspection (knowing how much strain had been put on it).

He’s lucky the mast didn’t come down while he was up there, as there were some pretty serious points of failure just about to give. If he’d gone out sailing without checking it out first he could have been in big trouble!

Along with checking the boat for any damage it’s a great idea to do a storm debrief with your crew. Think through the things you managed really well and the things you would have done differently (there’s always something!)

Every scenario is so different, so it’s great to build up a mental picture of things that worked in certain situations and things that didn’t. Next time you get caught in bad weather you’ll be even better prepared.

In conclusion, sailing in a storm is undoubtedly one of the most challenging and intense experiences a sailor can face. It will test your skills, courage, and resilience to the core.

Yet, it is also during these tempestuous moments that the true spirit of sailing shines through. The stormy seas teach us invaluable lessons about ourselves and our abilities as sailors. It’s where I have really built confidence in my sailboat and my own strengths.

While the prospect of sailing in a storm may seem daunting, it is important to remember that with proper preparation, knowledge, and seamanship, it is possible to navigate through even the fiercest of storms. You’ll probably give up long before your sailboat will!

Understanding weather patterns, having a well-maintained vessel, and equipping oneself with the necessary safety gear are crucial steps to minimize risks.

During a storm, it is essential to remain calm and focused. Keep a clear mind, assess the situation, and make informed decisions. Trust your instincts and rely on your training and experience. Remember that storms are temporary, and your skill as a sailor will guide you towards safer waters.

Sailing in a storm also fosters a profound connection with nature. It reminds us of the immense power and unpredictability of the sea. As the winds howl and the waves crash, there is an undeniable sense of awe and respect for the forces at play.

While I wasn’t holding on for dear life, I did have time to stare in awe at the power of the ocean and it was quite an incredible feeling to be in the middle of it all. It’s the main reason people think of sailing as dangerous , and I could see why in that moment!

Lastly, sailing in a storm builds character. It teaches us perseverance, adaptability, and problem-solving skills. It cultivates a sense of resilience and fortitude that extends far beyond the realm of sailing.

In the end, while sailing in a storm may not be for the faint of heart, it is an experience that pushes us to our limits and reveals the true strength within us. But please don’t head out into one on purpose – one will find you soon enough!

It is in the face of adversity that we grow as sailors and as individuals. So, if you ever find yourself caught in a storm at sea, embrace the challenge, trust your skills, and let the storm propel you towards a greater understanding of yourself and the remarkable world of sailing.

Storm Tactics for Heavy Weather Sailing

• By Bill Gladstone
• Updated: November 15, 2021

Storm tactics can be roughly defined as the ways to handle a storm once you’re in it. There are several proven choices, all of which intend to keep either the bow or stern pointing toward the waves. No one tactic will work best for all sailboats in all conditions. As skipper, it will be up to you to consider the best approach for your vessel, procure the right equipment, and practice with it before it’s needed.

Here we look at some active storm options that might work when conditions are still manageable and you want to actively control and steer the boat. Crew fatigue is a serious consideration when using active tactics.

Forereaching

Although not often mentioned as a tactic, it can be highly effective for combating brief squalls or moderate-duration storms. Here’s how to set up your boat for forereaching: Roll the jib away (especially if you have a large roller-furler genoa set); reef the main down to the second or third reef position; and sail on a closehauled course, concentrating on keeping the boat flat. It will be a comfortable ride, everyone will be relatively happy, and you will be making 2 to 3 knots on a close reach. Check your course over ground because increased leeway will cause your track to be much lower. This is a possibly useful tactic to claw off a lee shore. Note that not all boats will be at ease forereaching, so you’d better experiment with it ahead of time. Catamarans in particular will lurch and demonstrate much-increased leeway.

Motorsailing

Sometimes it’s necessary from a time or safety perspective to stow the jib and fire up the iron genny instead. Motorsailing lets you point high and make progress to windward. Motoring with no sails will not work well (or at all, in some cases), particularly in big seas, but a reefed mainsail will provide lateral stability and extra power. Trim the main, head up high enough to control your angle of heel, set the autopilot, and keep a lookout. Fuel consumption makes this a short-term option.

Here’s a tip: Make sure cooling water is pumping through the engine. On some sailboats, the water intake lifts out of the water when heeled. A further difficulty is that the pitching boat might stir sediment off the bottom of the fuel tank, which can, in turn, clog the fuel filter.

Running off and drogues

Sailing under storm jib and a deeply reefed mainsail or storm trysail provides the most control. If you don’t have storm sails, a reefed jib will give you the power to steer and control your boat in the waves. The boat must be steered actively to maintain control because no autopilot will be able to do this.

If excessive speed is a problem and steering becomes difficult, towing a drogue will slow the boat. A retrieval line should be set from the head of the drogue for when it is time to bring it back on board. If you don’t have a drogue, trailing warps might help slow the boat.

In a storm of longer duration, or when conditions become otherwise unmanageable, the situation might call for a skipper to consider passive storm tactics. When you are exhausted and you just want to quiet down the boat and maybe get some rest, there are other boathandling options available, depending on the sea state and the ­equipment you have onboard.

Heaving to can be an excellent heavy-weather tactic, though some boats fare better than others. Wouldn’t it be great if during a heavy-weather episode you could just slow everything way down? Imagine a short respite with a reduced amount of motion from the relentless pitching and pounding. A chance to regroup, make a meal, or check over the boat. Well, you can.

Heaving to allows you to “park” in open water. Hove-to trim has the jib trimmed aback (that is, to the wrong side), the reefed main eased, and the helm lashed down to leeward. The easiest way to do this is to trim the jib sheet hard and then tack the boat, leaving the sheet in place. Trimmed this way, the jib pushes the bow down. As the bow turns off the wind, the main fills and the boat moves forward. With the helm lashed down, the rudder turns the boat toward the wind. As the main goes soft, the jib once again takes over, pushing the bow down. The main refills, and the rudder pushes the bow into the wind again.

Achieving this balance will require some fine-­tuning, depending on the wind strength, your boat design and the sails you have. You might, for example, need to furl the jib most of the way in to match the wind strength. Trimming the main will ensure that the bow is at an angle to the waves, ideally pointing 40 to 60 degrees off. Modern fin-keeled boats do not heave to as well as more-traditional full-keel designs.

When hove to, the boat won’t actually stop. It will lie, as noted, about 40 to 60 degrees off the wind, sailing at 1 or 2 knots, and making leeway (sliding to leeward). Beware of chafe. When hove to, the jib’s clew or sheet will be up against the shroud and might experience wear damage. Monitor this regularly, and change the position of the sheet occasionally. You might not want to heave to for an extended time.

Deploying a sea anchor

A sea anchor is a small parachute deployed on a line off the bow. A sea anchor helps keep the bow pointed up into the waves so the boat won’t end up beam to the seas. Light displacement boats will pitch violently in high seas, and chafe and damage might occur to the bow, so setting up a bridle and leading it aft through a snatch block will allow the boat to lie at an angle to the waves, providing a more comfortable ride. A big concern when using a sea anchor is the load on the rudder as the waves slam the boat backward. Chafe on the sea-anchor bridle is another big factor, so the bridle must be tended regularly.

Remember, if you and your vessel are caught out in heavy-weather conditions, as a skipper, you must show leadership by setting an example, watching over your crew, offering relief and help to those who need it, and giving encouragement. Remember too, discomfort and fear can lead to fatigue, diminished performance, and poor decision-making. Don’t compromise the safety of the boat and crew to escape discomfort.

Few people get to ­experience the full fury of a storm. Advances in weather forecasting, routing and communications greatly improve your odds of avoiding heavy weather at sea, but you’re likely to experience it at some point, so think ahead of time about the tactics and tools available to keep your crew and vessel safe.

Heavy weather might not be pleasant, but it is certainly memorable, and it will make you a better sailor. Take the time to marvel at the forces of nature; realize that the boat is stronger than you think.

Happy sailing, and may all your storms be little ones!

How to Survive Sailing in a Storm: Tips and Tricks for a Safe Voyage

The thrill of sailing on calm waters is an experience like no other, but sometimes, Mother Nature has other plans. As a sailor, it’s crucial to be prepared for the unexpected, including sailing through a storm. 

The phrase “sail through the storm” may sound counterintuitive, but it refers to the actions you need to take to safely navigate stormy weather while aboard a sailing vessel. 

In this comprehensive guide, we’ll explore what to do when sailing in a storm, how ships survive these tempestuous conditions, and the steps you can take to ensure your safety.

Key Takeaways Sailing in a storm is not something to take lightly. It requires careful planning, preparation, and execution. The best way to avoid sailing in a storm is to check the weather forecast regularly and plan your route accordingly. If possible, seek shelter before the storm hits or sail away from its path. If you have to sail through a storm, you need to reduce your sail area, balance your boat, steer actively, and secure everything on deck and below. There are different storm tactics that you can use depending on the wind direction, wave height, sea room, and boat type. Some of the most common ones are sailing under storm sails, running before the storm with a drogue, heaving-to, lying ahull, or anchoring. No matter what tactic you choose, you need to monitor the situation closely and be ready to adapt if necessary. You also need to take care of yourself and your crew by staying hydrated, rested, warm, and calm.

What is a Storm?

Before we dive into the details of sailing in a storm, let’s first define what we mean by a storm. 

At this level, the sea is completely covered with long white patches of foam, and visibility is greatly reduced.

Of course, not all storms are created equal. Some storms are more severe than others, depending on factors such as wind direction, wind duration, air pressure, temperature, humidity, cloud cover, precipitation, lightning, thunder, etc. 

Some storms are also more localized than others, meaning they affect only a small area for a short time. For example, squalls are sudden bursts of strong wind that usually last for less than an hour and can occur in clear or cloudy weather.

The most dangerous storms for sailors are tropical cyclones (also known as hurricanes or typhoons), which are large rotating systems of clouds and thunderstorms that form over warm ocean waters. 

These storms can have wind speeds of over 74 knots (85 mph) and can cause massive waves, storm surges, flooding, landslides, and damage to coastal areas. 

Tropical cyclones are classified into five categories based on their maximum sustained wind speed:

Tropical cyclones usually form between June and November in the Atlantic Ocean and between May and November in the Pacific Ocean. 

They have different names depending on where they occur:

The best way to avoid sailing in a tropical cyclone is to stay away from its path. You can track the location and movement of tropical cyclones using satellite images, radio broadcasts, websites, apps, or other sources of information. 

You can also use tools such as the Saffir-Simpson Hurricane Wind Scale or the Dvorak Technique to estimate the intensity of a tropical cyclone based on its appearance.

How to Prepare for Sailing in a Storm

The best way to deal with sailing in a storm is to prevent it from happening in the first place. This means planning your trip carefully and checking the weather forecast regularly before and during your voyage. You should also have a contingency plan in case things go wrong.

Here are some steps you can take to prepare for sailing in a storm:

Check the Weather Forecast

The weather forecast is your best friend when it comes to sailing safely. You should always check the weather forecast before you leave port and update it frequently while you are at sea. You should also pay attention to any weather warnings or alerts that may indicate an approaching storm.

There are many sources of weather information that you can use depending on your location and equipment. Some of them are:

• VHF radio: You can listen to marine weather broadcasts from local stations or coast guard services that provide information on wind speed and direction, wave height and period, sea state, visibility, precipitation, cloud cover, air pressure, temperature, and humidity. You can also request specific weather information from some stations or services using voice or digital selective calling (DSC).
• HF radio: You can receive weather fax images or text messages from various stations around the world that transmit information on synoptic charts, satellite images, wind/wave analysis, tropical cyclone warnings, etc. You need an HF radio receiver and a modem or software to decode the signals.
• NAVTEX: You can receive text messages from coastal stations that broadcast information on navigational warnings, meteorological warnings, ice reports, search and rescue information, etc. You need a NAVTEX receiver or an HF radio receiver with NAVTEX capability to receive the messages.
• NOAA National Weather Service
• NOAA National Hurricane Center
• PredictWind
• Buoyweather
• PassageWeather
• WeatherTrack
• Barometer: You can measure the air pressure using a barometer or an electronic device that has a barometer function. You can use the barometer readings to detect changes in the weather conditions. A falling barometer indicates an approaching low-pressure system that may bring bad weather. A rising barometer indicates an approaching high-pressure system that may bring good weather.

When checking the weather forecast, you should look for signs of an impending storm such as:

• A rapid drop in air pressure
• A sudden increase in wind speed or direction
• A change in cloud type or cover
• A change in temperature or humidity
• A change in visibility or precipitation
• A presence of lightning or thunder
• The presence of waterspouts or funnel clouds

You should also compare different sources of weather information to get a more accurate picture of the situation. Sometimes different sources may have conflicting or outdated information due to errors or delays in transmission or reception.

Plan Your Route

Once you have checked the weather forecast, you should plan your route accordingly. You should avoid sailing into areas where storms are likely to occur or where they may trap you against land or other obstacles. You should also have alternative destinations or safe havens in case you need to change your plans or seek shelter.

There are different tools and methods that you can use to plan your route, such as:

• Paper charts: You can use paper charts to plot your course and waypoints using a pencil, ruler, compass, and dividers. You should also have a chart table or a flat surface where you can spread out your charts and keep them dry and secure. Paper charts are reliable and easy to use, but they can be bulky, expensive, and outdated.
• Electronic charts: You can use electronic charts on your laptop, tablet, smartphone, or dedicated chart plotter device. You can also download or update your charts online or offline. Electronic charts are convenient and interactive, but they can be inaccurate, incompatible, or corrupted. They also depend on electricity and GPS signals, which may fail in a storm.
• Online tools: You can use online tools such as OpenSeaMap , SailingEurope , or FastSeas to plan your route using your web browser. You can also access various features such as weather data, nautical charts, marina information, etc. Online tools are useful and versatile, but they require an internet connection, which may not be available or reliable at sea.

When planning your route, you should consider factors such as:

• Distance: You should calculate the distance between your starting point and your destination, as well as between each waypoint along the way. You should also estimate the time it will take you to cover the distance based on your boat speed and the expected weather conditions. You should plan to sail at a comfortable and safe pace, without pushing yourself or your boat too hard.
• Direction: You should determine the direction of your course and waypoints using magnetic bearings or true bearings. You should also account for the variation and deviation of your compass due to the earth’s magnetic field and your boat’s magnetic interference. You should also adjust your course for the effects of wind, current, and leeway on your boat’s movement.
• Depth: You should check the depth of the water along your route using depth soundings or contour lines on your charts. You should also be aware of the tide levels and currents that may affect the depth of the water at different times and locations. You should avoid sailing in shallow water or near rocks, reefs, wrecks, or other hazards that may damage your boat or cause grounding.
• Destination: You should choose your destination carefully based on your preferences and needs. You should also research your destination before you arrive, such as its facilities, services, regulations, customs, culture, etc. You should also have a backup destination in case your primary one is unavailable or unsuitable.

Prepare Your Boat

Surviving a storm requires a great level of preparedness and it all begins long before setting out on a sail. As such, your chances of weathering a storm will increase if your boat is properly prepared to endure bad days on the water.

A major part of controlling your boat and the crew in a heavy storm is being prepared for the worst. This means that you should have your boat properly rigged to easily access anything in short order. Whether you can see a storm coming from far away or see it within seconds and on top of your head, the boat should be well prepared to deal with any condition.

It’s fundamental to ensure that your lifelines are secure, the lines are strong and unworn, and all the emergency gear is on board and up to date. You should also update yourself on the weather on the days you’re planning to go out though it may be inaccurate.

Some of the things you should check and prepare before sailing include:

• Hull integrity : Check for any cracks, leaks, or damage on the hull that could compromise its strength or water tightness. Repair any defects or reinforce any weak spots as needed.
• Rigging : Check all the standing rigging (mast, shrouds, stays) and running rigging (halyards, sheets) for any signs of wear or damage. Replace any frayed or broken lines or fittings. Lubricate any moving parts such as blocks or winches. Make sure all the lines are neatly coiled and secured to prevent tangling or tripping.
• Sails : Check all your sails for any tears or holes that could worsen in high winds. Repair any damage or replace any worn-out sails as needed. Make sure you have at least one set of storm sails (storm jib and trysail) on board that are easy to hoist and lower. Reefing lines should be ready to use at any time.
• Engine : Check your engine for any issues that could affect its performance or reliability. Change the oil and filter if needed. Check the fuel level and quality. Make sure you have enough spare fuel on board. Test the engine before leaving the dock to make sure it starts and runs smoothly.
• Batteries : Check your batteries for any corrosion or damage that could affect their capacity or charge. Make sure they are fully charged before leaving the dock. Test all your electrical systems (lights, instruments, radios) to make sure they work properly.
• Bilge pumps : Check your bilge pumps for any clogs or malfunctions that could prevent them from working effectively. Make sure they are wired correctly and have enough power supply. Test them before leaving the dock to make sure they pump water out of the bilge.
• Emergency gear : Check all your emergency gear for any damage or expiration dates that could affect their usefulness or safety. Make sure you have enough life jackets, harnesses, tethers, liferaft, EPIRB, VHF radio, distress flares, fire extinguishers, first aid kit, etc. on board, and that they are easily accessible and visible. Make sure everyone knows how to use them properly.

Prepare Yourself

Your boat is not the only thing that needs to be prepared for sailing in a storm. You also need to prepare yourself mentally and physically for the challenge. You need to be aware of the risks and consequences of sailing in a storm and be ready to face them. You also need to take care of your health and well-being during the storm.

Here are some steps you can take to prepare yourself for sailing in a storm:

You need to learn as much as you can about sailing in a storm before you encounter one. You need to read books, articles, blogs, forums, etc. that provide information, advice, tips, tricks, stories, etc. about sailing in a storm. 

You also need to watch videos, podcasts, webinars, etc. that show demonstrations, explanations, interviews, testimonials, etc. about sailing in a storm. 

You also need to take courses, workshops, seminars, etc. that teach skills, techniques, strategies, etc. about sailing in a storm. Some examples of learning resources are:

• Storm Tactics Handbook by Lin and Larry Pardey
• Sailing in Storms by Sailing La Vagabonde
• Podcast by The Boat Galley
• Heavy Weather Sailing Course by NauticEd

You need to practice your skills and techniques for sailing in a storm before you face one. You need to practice sailing in different wind and wave conditions and try different storm tactics. 

You also need to practice using your gear and equipment and test their functionality and reliability. You also need to practice communicating with your crew and other boats or shore stations and test their availability and clarity.

The best way to practice sailing in a storm is to sail in moderate weather conditions that simulate some aspects of a storm, such as strong winds, choppy waves, low visibility, etc. 

You should avoid sailing in extreme weather conditions that may endanger your safety or damage your boat. You should also avoid sailing alone or without proper supervision or assistance.

When practicing sailing in a storm, you should follow these steps:

• Choose a suitable location that has enough sea room and no obstacles or hazards.
• Check the weather forecast and choose a time that has favorable conditions for practicing.
• Inform someone on shore about your plan and expected return time.
• Prepare your boat and yourself as if you were sailing in a real storm.
• Sail out of the harbor and head into the wind and waves.
• Try different storm tactics such as reefing, heaving-to, running with a drogue, etc.
• Use your gear and equipment such as storm sails, life jackets, VHF radio, etc.
• Communicate with your crew and other boats or shore stations using voice or signals.
• Monitor the situation closely and be ready to adapt if necessary.
• Sail back to the harbor when you are done practicing or when the conditions change.

You need to rest well before sailing in a storm because you may not get much sleep during the storm. You need to sleep at least eight hours before leaving port and take naps whenever possible while at sea. 

You also need to avoid alcohol, caffeine, or drugs that may affect your sleep quality or alertness.

Sleeping well before sailing in a storm will help you:

• Reduce fatigue and stress and improve mood and motivation
• Enhance memory and learning and improve decision-making and problem-solving
• Boost immunity and healing and prevent illness and injury

You need to eat well before sailing in a storm because you may not have much appetite during the storm. You need to eat balanced meals that provide enough calories and nutrients to sustain your energy and health. 

You also need to avoid spicy or greasy foods that may cause indigestion or nausea.

Eating well before sailing in a storm will help you:

• Maintain blood sugar and blood pressure levels and prevent hypoglycemia or hypertension
• Support muscle and bone strength and prevent weakness or injury

You need to hydrate well before sailing in a storm because you may lose a lot of fluids through sweating, vomiting, or diarrhea during the storm. You need to drink plenty of water or electrolyte drinks that can replenish your hydration and electrolyte levels. 

You also need to avoid alcohol, caffeine, or carbonated drinks that may dehydrate you or upset your stomach.

Hydrating well before sailing in a storm will help you:

• Prevent dehydration and heatstroke and improve thermoregulation and cooling
• Maintain blood volume and circulation and prevent hypotension or shock
• Support kidney and liver function and prevent infection or toxicity

How to Sail Through a Storm

If you have done everything you can to prepare for sailing in a storm, but you still find yourself in one, don’t panic. You need to stay calm and focused and follow some basic principles and procedures to sail safely through the storm.

Here are some steps you can take to sail through a storm:

Reduce Sail Area

The first thing you need to do when sailing in a storm is to reduce your sail area. This will reduce the wind pressure on your boat and make it easier to control and balance. 

You need to reef your sails as soon as possible, before the wind gets too strong and makes it difficult or dangerous to do so. You also need to furl or stow any unnecessary sails, such as spinnakers, genoas, or staysails.

The amount of sail area you need to reduce depends on the wind speed, the wave height, the boat type, and your comfort level. 

As a general rule, you should reef your sails when the wind speed reaches 15 knots (17 mph) and reduce them further for every 5 knots (6 mph) increase. 

You should also reef your sails when the wave height reaches 1 meter (3 feet) and reduce them further for every 0.5 meters (1.5 feet) increase.

You should always reef your mainsail first, then your headsail. This will keep your boat balanced and prevent weather helm (when the boat wants to turn into the wind) or lee helm (when the boat wants to turn away from the wind). You should also reef your sails evenly and symmetrically, without leaving any loose or flapping parts.

If you have storm sails on board, you should hoist them when the wind speed reaches 40 knots (46 mph) or more. You should lower your regular sails completely and secure them on deck or below. 

You should hoist your storm jib just forward of the mast and your storm trysail on a separate track on the mast or on the boom.

Balance Your Boat

The second thing you need to do when sailing in a storm is to balance your boat. This will reduce the heel angle and rolling motion of your boat and make it more stable and comfortable. 

You need to adjust your sail trim, your weight distribution, and your ballast system (if you have one) to achieve a balanced boat.

The sail trim is how you set the angle and shape of your sails relative to the wind direction and strength. You need to trim your sails so that they are not too tight or too loose, but just right. 

You also need to trim your sails so that they are not too full or too flat, but just right. A well-trimmed sail will have a smooth and even curve along its luff (front edge) and leech (back edge), without any wrinkles or creases.

The weight distribution is how you arrange the weight of your crew and gear on board. You need to distribute your weight so that it is not too far forward or too far aft, but just right. 

You also need to distribute your weight so that it is not too far to windward or too far to leeward, but just right. A well-distributed weight will keep your boat level and centered, without any pitching (up-and-down motion) or yawing (side-to-side motion).

The ballast system is how you use water tanks or movable weights to adjust the stability of your boat. You need to use your ballast system so that it is not too full or too empty, but just right. 

You also need to use your ballast system so that it is not too far forward or too far aft, but just right. 

A well-used ballast system will increase the righting moment (the force that keeps your boat upright) and decrease the capsizing moment (the force that tips your boat over).

Steer Actively

The third thing you need to do when sailing in a storm is to steer actively. This will help you avoid being hit by breaking waves or being pushed off course by gusts of wind. 

You need to steer your boat so that it is not too close or too far from the wind direction, but just right. You also need to steer your boat so that it is not too fast or too slow, but just right.

The best way to steer actively is to use a combination of visual cues and instruments. You need to look at the wind indicator (such as a Windex ) on top of your mast or on your sail to see where the wind is coming from. 

You also need to look at the waves around you to see where they are going and how big they are. You also need to look at the compass on your dashboard or on your wrist to see what direction you are heading.

You also need to listen to the sound of the wind in your ears and feel its pressure on your face and body. You also need to listen to the sound of the water against your hull and feel its movement under your feet and seat. 

You also need to listen to the sound of your sails flapping or luffing and feel their tension on your hands.

You also need to use instruments such as GPS, AIS, radar, autopilot, etc. to see where you are, where other boats are, where obstacles are, etc. 

You also need to use instruments such as a speedometer, tachometer, anemometer, etc. to see how fast you are going, how fast your engine is running, how fast the wind is blowing, etc.

You should steer actively using small and smooth movements of the helm or tiller to keep your boat on course and speed. 

You should avoid steering aggressively using large or jerky movements of the helm or tiller that may cause your boat to lose control or speed.

Choose Your Storm Tactic

The fourth thing you need to do when sailing in a storm is to choose your storm tactic. This will help you cope with the wind and wave conditions and reduce the risk of damage or injury. 

You need to choose a storm tactic that suits your boat type, your crew’s ability, and your situation. You also need to have the right equipment and skills to execute your storm tactic.

There are different storm tactics that you can use, such as:

Forereaching

This is when you sail close-hauled with reduced sail area and maintain a slow but steady speed into the wind and waves. This tactic is good for short-duration storms or when you need to stay close to your position. It is also good for boats that have good upwind performance and can handle steep waves. The advantages of this tactic are:

• It keeps the boat stable and balanced
• It reduces the impact of breaking waves
• It allows you to change course or tack if needed

The disadvantages of this tactic are:

• It can be tiring and uncomfortable for the crew
• It can cause excessive leeway and drift
• It can expose the boat to wind shifts or gusts

Running off

This is when you sail downwind with reduced sail area and let the wind and waves push you away from the storm center. This tactic is good for long-duration storms or when you have enough sea room to run. It is also good for boats that have good downwind performance and can handle following seas. The advantages of this tactic are:

• It keeps the boat fast and agile
• It reduces the apparent wind speed and noise
• It allows you to outrun the storm or reach a safe haven
• It can be risky and challenging for the crew
• It can cause broaching or surfing
• It can expose the boat to breaking waves or rogue waves

This is when you stop the boat by setting the sails and rudder in opposite directions and creating a slick of turbulent water that acts as a brake. This tactic is good for extreme storms or when you need to rest or wait. It is also good for boats that have a balanced sail plan and a deep keel. The advantages of this tactic are:

• It keeps the boat calm and steady
• It reduces the stress and fatigue of the crew
• It allows you to conserve fuel and water
• It can be difficult and dangerous to set up or resume sailing
• It can cause drifting or leeway

Lying ahull

This is when you drop all sails and let the boat drift freely with no steerage. This tactic is good for last-resort situations or when you have no other option. It is also good for boats that have a strong hull and a low profile. The advantages of this tactic are:

• It keeps the boat simple and passive
• It requires no effort or skill from the crew
• It allows you to abandon ship if needed
• It keeps the boat vulnerable and unpredictable
• It increases the risk of damage or injury
• It offers no control or direction

Survive the Storm

The fifth and final thing you need to do when sailing in a storm is to survive the storm. This means that you need to do whatever it takes to keep yourself, your crew, and your boat alive and intact until the storm passes. You need to monitor the situation constantly and be ready to adapt or change your plan if necessary. You also need to communicate with your crew and other boats or shore stations and seek help if needed.

Here are some tips to help you survive the storm:

Stay calm and positive

The most important thing you need to do when sailing in a storm is to stay calm and positive. Panic and despair will only make things worse and cloud your judgment. 

You need to trust your boat, your crew, and yourself and believe that you can make it through the storm. You also need to encourage and support your crew and keep their morale high. 

You can use humor, music, games, or stories to lighten the mood and distract from the stress.

Stay alert and aware

The second most important thing you need to do when sailing in a storm is to stay alert and aware. Complacency and negligence will only increase the danger and reduce your chances of survival. 

You need to watch the wind, the waves, the clouds, and the horizon for any signs of change or improvement. You also need to check your boat, your gear, your instruments, and your crew for any signs of damage or injury. 

You also need to listen to weather updates, distress calls, or safety messages on your radio or phone.

Stay safe and secure

The third most important thing you need to do when sailing in a storm is to stay safe and secure. Injury and damage will only worsen the situation and compromise your recovery. 

You need to wear your life jacket, your harness, and your helmet at all times and clip yourself to a strong point on the boat. You also need to secure all loose items on deck or below and close all hatches and ports. 

You also need to avoid going overboard, getting hit by flying objects, or falling down.

Stay warm and dry

The fourth most important thing you need to do when sailing in a storm is to stay warm and dry. Hypothermia and dehydration will only weaken your body and mind and impair your performance. 

You need to wear waterproof and breathable clothing that can protect you from the wind, rain, spray, and cold. You also need to drink plenty of water or electrolyte drinks that can replenish your hydration and electrolyte levels. 

Stay fed and rested

The fifth most important thing you need to do when sailing in a storm is to stay fed and rested. Hunger and fatigue will only lower your energy and health and affect your decision-making and problem-solving. 

You need to eat balanced meals that provide enough calories and nutrients to sustain your energy and health. You also need to sleep at least eight hours before leaving port and take naps whenever possible while at sea. 

Frequently Asked Questions

Here are some of the most frequently asked questions about sailing in a storm:

To sail through the storm means to overcome a difficult or challenging situation with courage and resilience. It can also mean enduring or surviving a storm at sea.

Ships survive storms by following some of the same principles as sailboats: reducing speed, balancing weight, steering into or away from the wind and waves, using stabilizers or ballast tanks, and seeking shelter or open water as needed.

Yes, you should lower sails in a storm, or at least reduce sail area by reefing or switching to storm sails. This will help you control your boat better and prevent damage from high winds.

Sailing ships do different things in a storm depending on their size, type, design, crew, equipment, and situation. Some of the common things they do are: reefing sails, switching to storm sails, running before the storm, heaving-to, lying ahull, forereaching, etc.

You steer a ship in a storm by using your rudder and sails (or engine) to adjust your course and speed according to the wind and wave direction. You should try to avoid sailing on a reach across tall breaking waves, as they can roll your ship over. You should also try to sail away from the storm’s path, especially its dangerous semicircle.

Sailing in a storm is one of the most challenging and rewarding experiences that a sailor can have. It requires a lot of preparation and skill to sail safely through a storm and survive its fury. It also requires a lot of courage and resilience to face the storm and overcome its fear.

By following the steps outlined in this article, you can increase your chances of sailing in a storm successfully and enjoy its thrill. You can also learn valuable lessons and gain confidence from sailing in a storm that will make you a better sailor.

Remember, the best way to deal with a storm is to avoid it if possible, prepare for it if inevitable, and survive it if necessary.

The Storm Anchoring Techniques

Proper storm anchoring techniques are essential for ensuring the safety of your boat and family during a storm while sailing the open seas.

Sailing the open seas is an exhilarating and fulfilling experience, but it also comes with its fair share of challenges. One of the most significant challenges that sailors face is dealing with storms. Proper storm tactics and preparation are essential for ensuring the safety of your boat and your family. In this article, we will discuss storm anchoring techniques, which are crucial for keeping your boat secure during a storm.

Table of Contents

Understanding storm anchoring, types of anchors, anchor rode selection, setting the anchor, scope and chafe protection, multiple anchors, storm anchor retrieval.

Storm anchoring is the process of securing your boat to the seabed using an anchor and rode (the line or chain connecting the anchor to the boat) to prevent it from drifting or being pushed ashore during a storm. The primary goal of storm anchoring is to keep your boat in a safe position, minimizing the risk of damage or injury.

When selecting an anchorage, consider the following factors:

• Protection : Choose a location that offers protection from the wind and waves. This may include natural features such as headlands, islands, or reefs, or man-made structures like breakwaters or marinas.
• Holding Ground : The seabed should provide good holding for your anchor. Sand, mud, and clay are generally considered the best holding grounds, while rock, coral, and grass are less reliable.
• Swing Room : Ensure there is enough space for your boat to swing around the anchor without colliding with other boats or obstacles.
• Depth : The water should be deep enough to accommodate your boat’s draft and allow for a sufficient scope (the ratio of rode length to water depth).

There are several types of anchors available, each with its own advantages and disadvantages. The most common types of anchors used for storm anchoring include:

CQR (Plow) Anchor : This anchor has a hinged shank and plow-shaped fluke, which allows it to dig into the seabed and provide excellent holding power. It is suitable for a variety of bottom conditions, including sand, mud, and clay.

Delta Anchor : Similar to the CQR anchor, the Delta anchor has a fixed shank and a concave fluke, which provides even better holding power in soft bottoms. It is also effective in harder bottoms, such as rock and coral.

Bruce (Claw) Anchor : This anchor has a three-pronged design that provides good holding power in most bottom conditions, although it may struggle in very soft mud. It is also less likely to foul on underwater obstacles.

Danforth (Fluke) Anchor : This lightweight anchor has a large surface area, making it ideal for soft bottoms like sand and mud. However, it may not perform as well in harder bottoms or areas with heavy grass or seaweed.

When choosing an anchor for storm anchoring, it is essential to select one that is appropriately sized for your boat. A general rule of thumb is to use an anchor that weighs 1 pound for every foot of boat length. However, this may vary depending on the specific anchor type and the conditions in which it will be used.

The anchor rode is the line or chain that connects your boat to the anchor. There are two primary types of anchor rode: chain and rope. Each has its own advantages and disadvantages.

Chain Rode : Chain rode is heavy and durable, providing excellent abrasion resistance and helping to keep the anchor shank low to the seabed, which improves holding power. However, chain rode is more expensive and requires a windlass (a mechanical device used to raise and lower the anchor) for handling.

Rope Rode : Rope rode is lighter and more affordable than chain rode, making it easier to handle without a windlass. However, rope rode is more susceptible to chafe and abrasion, which can weaken it over time.

For storm anchoring, it is recommended to use a combination of chain and rope rode. The chain portion should be at least the length of your boat, while the rope portion should be long enough to provide the necessary scope.

Properly setting the anchor is crucial for ensuring that it holds during a storm. Follow these steps to set your anchor:

• Approach the anchorage slowly, heading into the wind or current.
• When you reach the desired location, lower the anchor to the seabed while maintaining forward momentum. This will help the anchor dig into the bottom.
• Once the anchor is on the bottom, slowly reverse your boat while paying out the rode. This will help the anchor to set and bury itself in the seabed.
• When you have reached the desired scope, secure the rode to a cleat or anchor roller on your boat.
• Gently back down on the anchor using your engine to ensure that it is set and holding. If the anchor drags, repeat the process.

The scope is the ratio of rode length to water depth and is a critical factor in ensuring that your anchor holds during a storm. A general rule of thumb is to use a scope of 7:1 for storm anchoring, meaning that for every foot of water depth, you should have 7 feet of rode deployed.

Chafe protection is essential for preventing damage to your rode during a storm. Chafe can occur when the rode rubs against the boat’s bow, anchor roller, or other obstacles. To protect your rode, use chafe guards or hose sections to cover the areas where chafe is likely to occur.

In some situations, it may be necessary to deploy multiple anchors to provide additional holding power or to prevent your boat from swinging into obstacles. There are several methods for setting multiple anchors, including:

• Bahamian Moor : This technique involves setting two anchors in a line, with one anchor set directly upwind of the other. This can help to limit the boat’s swing and provide additional holding power.
• V-Formation : This method involves setting two anchors at a 45-degree angle from the bow, creating a V-shape. This can help to prevent the boat from swinging side-to-side during a storm.
• Tandem Anchoring : This technique involves attaching a second anchor to the rode of the primary anchor, effectively creating a chain of anchors. This can provide additional holding power in extreme conditions.

After the storm has passed, it is essential to retrieve your anchor(s) carefully to avoid damage to your boat or the anchor itself. Follow these steps to retrieve your anchor:

• Approach the anchor slowly, heading into the wind or current.
• Use a windlass or manual effort to raise the anchor rode until it is vertical.
• If the anchor is stuck, try using your boat’s engine to gently pull it free. Be cautious not to put too much strain on the rode or anchor.
• Once the anchor is free, raise it to the surface and secure it to your boat.

Storm anchoring is a critical skill for sailors who want to ensure the safety of their boat and family during a storm. By selecting the appropriate anchor and rode, setting the anchor correctly, and using proper scope and chafe protection, you can significantly increase the chances of your boat remaining secure during a storm. Additionally, understanding how to deploy multiple anchors and retrieve them safely after the storm has passed is essential for successful storm anchoring.

Heavy Weather Sailing

Best Sailing Tactics for High Winds and Waves

Many sailors both beginning and experienced fear storms as the greatest danger on the water, even though more emergencies and fatalities occur during times of relative calm. Nonetheless, strong winds and high waves can wreak havoc on a sailboat and any sailor who might be caught by even a summer thunderstorm, or a longer-lasting and greater storm offshore, should know how to stay safe in heavy weather.

Storm Sailing Tactics

It's often said that boats are stronger than people, meaning your first priority is to protect yourself. Be sure to have and use the right safety gear, such as PFDs and harnesses or tethers to keep you on the boat. The boat's motion will be more severe in storm conditions and taking action early will prevent injury and prevent seasickness that can further endanger your safety. Consider the following issues and strategies for keeping the boat under control in storm conditions.

Avoiding Shallows

When the heavy weather begins or threatens, the first impulse is often to drop the sails, start up the motor and head for land. If you can safely reach a harbor and return to a dock or mooring, this may be your safest option. Be aware that wind and waves can rapidly turn shallow areas or narrow channels into a more dangerous place than open water, especially if the storm will be short-lived and it's mostly a matter of waiting it out.

Waves become steeper and more likely to break in shallow areas, making it difficult to control the boat. Consider the risks if your engine were to die and the wind rapidly blow you onto the rocks or other obstructions. If the wind is blowing toward shore, it can also be risky to attempt to anchor, because the boat may go aground if the anchor drags. It is difficult and sometimes dangerous to try to reset an anchor in storm conditions. You may have better options staying in open water and riding out the storm using the tactics described below.

As soon as the wind begins or is anticipated to increase, it's time to reef the sails. The old saying is that if you are wondering whether you should reef, then it's already past time to do so. You don't want a lot of sail up when a strong gust hits, potentially leading to capsize. It's also much easier to reef the mainsail or furl the jib while the wind is still manageable, and it can be dangerous to have to leave the cockpit to reef the main or drop the jib once the boat is being tossed or strongly heeled over by the wind.

Remember that if you are sailing downwind when the wind increases, you feel its effects less and can be shocked to see how hard it's blowing when you turn up into the wind to reef. Always pay attention and reef early. Monitor changes in the wind so that you can reef early when it's easy, rather than late, when it's difficult or dangerous. You can learn to read the wind or use an inexpensive handheld wind meter.

The following storm tactics are more applicable when offshore or nearshore and expecting the storm to last for some time.

Storm Sails

Offshore voyagers typically carry special sails for use in high winds. Regular sails can be reefed or furled only so far and still maintain an efficient shape and the fabric of regular sails is generally too light for high winds. A storm jib used with or without a trysail replacing the main generally allows one to continue sailing in stronger winds, usually on a course that minimizes the effects of waves.

Racing sailors, for example, usually have a selection of sails and may prefer to keep going rather than wait out the storm with a different tactic that would essentially stop the boat's progress. Many coastal and recreational sailors do not carry these extra sails, however, and prefer a different strategy, like heaving to.

Lying Ahull

Lying ahull simply means dropping the sails and letting the boat fare for itself, possibly while you go below to seek shelter. This strategy may work in limited situations when the waves are not too big, the boat is far enough from land and shipping channels so that it doesn't matter how far the boat drifts downwind. In some cases, it may be necessary to lie ahull to attend to an injury or simply because one is too exhausted to continue active strategies.

If the waves are large and breaking, however, there is a significant risk of the boat being rolled and capsizing because it will tend to lie broadside to the waves. Never attempt this in an open boat that would rapidly fill with water and sink; a larger boat with a closed cabin should bob back up. Still, this is seldom the preferable approach to take in a serious storm.

Using a Sea Anchor

Offshore voyagers are more likely to have invested in a sea anchor, which is like a parachute deployed underwater to keep the bow pointed into the wind and waves. Breaking waves causes less damage to the bow than from any other angle and the boat is less likely to capsize or roll when facing large waves. A sea anchor can be expensive, however, and takes time and skill to deploy. This is a strategy used for a serious storm that will last for some time, not a passing squall or thunderstorm.

Heaving to is a time-honored storm tactic preferred by many sailors. The boat is turned close to the wind, the jib (partly furled or smaller jib hoisted) is backwinded, the helm is locked into position and the boat slowly jogs along without turning broadside to the waves, as when lying ahull. This is a valuable skill for all sailors and it's a good idea to practice it in your own boat to know how best to accomplish it when needed.

An advantage of heaving to is that you don't have to stay at the helm but can go below, if it is safe to do so, or duck beneath the dodger. The boat remains pointed close enough to the wind that it is less likely to be rolled by a breaking wave. In addition, the downwind sliding motion of the hull produces a slick in the water that makes it less likely for a wave to break on the boat.

Heaving to using a sea anchor is one of the best conservative storm tactics. The anchor is adjusted off to one side to help the bow point closer to the wind than when heaving to without a sea anchor, but the boat still drifts back slightly to make a slick. World-traveling Lin and Larry Pardey's video "Storm Tactics" and the book "Storm Tactics Handbook" argues persuasively for this technique and illustrates how it is accomplished.

Running Off

The final heavy weather tactic, used by some accomplished sailors, is to run off downwind. Reduce sail as needed and in the true storm-force wind you can continue sailing downwind "under bare poles" with no sail at all. As the wind increases, the greatest danger is going too fast, even without the sail, in which case the boat may come down a large wave and bury the bow in the back of the wave in front. This may cause the boat to pitchpole end over end or otherwise capsize. To slow the boat, sailors historically trailed long, heavy lines off the stern and modern sailors can use a special drogue for that purpose.

While some sailors swear by running off, this tactic requires constant skillful steering. If the stern is not kept perpendicular to approaching waves, a wave can push the stern around to one side, causing a broach and likely capsize.

Other Resources

These brief descriptions serve only to introduce tactics for heavy weather sailing. Any boat owner who may ever be in a high winds situation, however, should be prepared to take appropriate action. At the minimum, it is important to be familiar with reefing and heaving to. Consider a good book on seamanship, such as " Chapman's Piloting & Seamanship " or " The Annapolis Book of Seamanship ".

How to Sail through a Storm: Waves, Sails, Tactics

On the open ocean and in the middle of a storm is when your will, strength, and endurance are tested to their bitter limits. The natural elements from the huge swells to the gusty winds are just a few things you have to worry about. There will also be exhausted crew members and passengers. Her some tips to sail through a storm!

Finding yourself sailing in big waves is when you make sure your best steereris at the helm.  Big waves in a storm will test the most experienced sailor.

Try not to sail on a reach across big breaking waves as they can cause a boat to roll.  Always keep your speed up to aid steering and try to move toward flat spots.  To minimize the risk of a wave washing across the deck only turn the sail in thesmooth water.

Should folding of the sail not reduce enough speed, you should use the trysail and storm jib (storm sails).  Storm sails are small, but the sails are perfectly proportioned for high winds.  Newer boats have the trysail attached to the boom, with the storm jib set forward of the mast – this keeps the boat balanced.

When facing a storm, there are two possible scenarios – avoid it or head for more space in the open ocean.  Storms these days hardly ever arrive unexpectedly due to technological advances and satellite tracked weather patterns.  There is a clear danger in being caught up by the storm should you decide to avoid it.  And with less maneuvering space, there is a chance of being blown on shore the closer you find yourself to land.  The rule of thumb is to stay away from land and to sail away from the storm – looking for a clear path.

There are numerous storm tactics to choose from, and all with the same purpose.  Tactics aim to lessen the strain and fight it takes to get one of the boat’s ends to point towards the waves.  There is no one storm tactic that works for all boats in every storm.

Sailing with storm sails is one option as the sails provide enough power to allow you to steer and gain control in the waves.  You can also try to steer the boat ahead of the storm towards the waves.  However, you will need a lot of space and constantly steer into the waves.

Another tactic is to lie ahull.  This entails you to fold down all the sails and lie and wait it out.  It is a less reliable tactic but one that does not require a lot of work or strain.  Your main concern is losing control of the boat and ending up with the side of the boat facing the waves.

Ultimately, the best tactic or way to sail through a storm is to avoid it entirely…  Storms are cold, wet, miserable, and highly dangerous out at sea.  It is a truly unforgettable experience but does not confuse a sense of adventure out on the seas with a dangerous situation.  Never comprise the safety of your crew, passengers, and yourself.

Sailing in a Storm: It’s Not as Difficult as You Think

Things about heavy weather boat handling you should know.

Any boater would rather avoid sailing in a storm than have to face its challenges. But despite the best-laid plans, it’s possible to get caught in unexpected heavy weather while on the water.

The most important thing to know if this happens to you is to stay calm. You may find yourself on the water with bad weather approaching faster than you can get away from it. But there are some key steps you can take to keep everyone on board safe and make it back to port.

In this blog, we will detail the signs that the weather is turning stormy, how to prepare for a bad weather encounter and the first key steps to take fast. We’ll also list some heavy-weather boat handling techniques and tips for recreational power boats and sailboats in storms.

>> Also, be sure to check out our emergency boating kit checklist

Can You Avoid Sailing in a Storm?

When at all possible, try to avoid being on the water during stormy weather. The best way to avoid getting caught out is by checking the marine weather forecast before any planned trips. The forecast contains marine weather for current conditions and predictions for the next 48 hours, so check at least a day ahead of your trip for any storm warnings.

If a strong storm is coming into shore, even boats moored at a marina may need some protection. These 10 tips to stormproof your boat are a good starting point.

Once you are out on the water, you can continue to monitor the marine weather forecast over your VHF radio channel 21b (storm forecasts will be relayed on the coastguard channel 16 also). Remember to keep an eye on the horizon for signs of heavy weather too. 

Some signs of bad weather approaching include:

• Clouds : flat clouds getting lower and thicker, vertical clouds that are rising, or dark clouds are all warnings of bad weather.
• Temperature : watch for sudden temperature drops.
• Wind : sudden increase in the wind or significant direction change should be noted.
• Flashes on the horizon : indicate a lightning storm.

Spotting these changing weather patterns soon enough may allow you to get back to land before getting caught in it.

Be Prepared for Bad Weather on the Water

Being prepared will help you to sail successfully through a storm. Educate yourself about heavy weather sailing techniques, what to do if someone goes overboard and how to report a Mayday situation.

Ensure required emergency equipment is on board and easy to access should you need it, including:

• Sound signaling equipment
• Lifejackets or PFDs for all passengers
• Anchors – in addition to a regular anchor, a sea anchor may be helpful in a storm. Sea anchors are cones of canvas material that are attached to the bow and slow downwind drift.

For more information about the safety equipment that you are legally required to carry on your vessel, check Transport Canada’s Safe Boating Guide .

Before heading out on a cruise, research protected anchorages in the area in case you need to seek shelter. This list of protected anchorages in the Gulf Islands is a good starting point. 

What to do When a Storm Hits Without Warning

If you do find yourself sailing into the wind and heavy waves, take these steps right away:

• Have everyone onboard put on a lifejacket.
• Reduce your speed. This gives you more control and makes it less likely your vessel will slam into a wave.
• Turn your running lights on so you are visible to others.
• Chart and log your current position.
• Find the closest safe port on the charts. Don’t try to get back to your home port if there is another option close by. 
• Passengers should go into the cabin and sit in the centre of the boat. If you are in an open boat with no cabin, passengers are to sit on the floor in the centre of the boat, away from metal objects.
• Close all hatches, ports and windows to prevent water from getting into the boat.
• Pump the bilges. Too much water on board can unbalance the boat in big waves.
• Tie down or store any loose items, so they don’t move around and cause an injury risk.

On a sailing boat:

• Reef your mainsail to make the surface area smaller and slow your travelling speed.
• Alternatively, switch to storm sail and jig.
• Ensure everyone on deck has a harness and is attached to jack lines/lifelines.

Heavy Weather Boat Handling and Sailing Techniques

Once you have done all the immediate things required to keep your passengers safe and have a handle on your position, your main aim is to get to a safe mooring or place to shelter. 

Here are some tips for handling your vessel in rough water:

Heavy weather boat handling for the recreational motor vessel:

• Slow your speed to equal the speed of the waves, this will help prevent broaching and put less pressure on the structure of the boat.
• Point the bow of the yacht into the waves at a 45-degree angle to avoid tipping or swamping.
• Tack the boat if needed to prevent sailing parallel to waves.
• Don’t sail too close to shore unless you are approaching moorage. There is always a risk of being blown onto shoreline rocks.
• If you run out of fuel or suffer engine failure, deploy your sea anchor and regular anchor to hold a safe position without tip

Heavy weather sailing techniques for sailing boats:

• Point one end of the boat towards the waves 
• If you haven’t already, switch to storm sail and jib. These small sails help to slow the vessel significantly while still allowing directional control.
• Deploy a sea anchor from the bow to prevent the sailboat from tipping. 
• If the storm becomes too heavy to ride out or you need physical rest, consider ‘Heaving To .’ This technique positions the sails, so they work against each other and hold the boat in place. Add an anchor to prevent drift.

Remember to continue to monitor the emergency VHF channel and keep a watch out for obstacles or other boats in the water. If you are in an emergency situation, taking on water, have hit an object, or have a man overboard – make a mayday call immediately.

If You Are Caught In A Storm In Your Boat, What Should You Do?

Boating is all fun and games until you’re caught off guard by bad weather. And as a storm brews, it might be challenging even for the most experienced of mariners to navigate safely. To help you out, we take a look at what to do when caught in a storm in your boat. 

When caught in a storm in your boat, the first thing you should do is keep calm and assess its intensity. Next is to ensure you’ve put on life jackets before stowing unneeded equipment and accessories. You should also close windows (and openings), stay away from metal and disconnect power cords.

In this article, we’ll examine what to do when caught in a storm in your boat. I’ll also share proven tips on how to prepare your boat for a storm. Let’s dive in. 

Table of Contents

What To Do When Caught In A Severe Storm

If you’re caught in a severe storm, the following tips will help you stay safe and reduce the chances of injury and lightning strikes. 

1. Assess The Storm’s Intensity

As hard (or impossible) as it may seem, the first thing you should do when caught in a storm is to examine its intensity. This means determining the direction of the winds, the size of waves, and the appearance of clouds.

Ideally, it should take you a minute or two to examine the storm’s severity. Knowing exactly what you’re dealing with will help ensure you take the right steps toward damage control. 

Understanding wind direction allows you to determine your escape routes (if any) and whether or not you should anchor the boat. 

Try as much as possible to assess the storm as you get closer to it and not when you’re already caught in it. 

2. Ensure Everyone Puts On Life Jackets 

As a good rule, everyone aboard a boat should always wear life jackets immediately when a storm is suspected to brew. The same applies to safety harnesses, which are vital to keeping all crew members and passengers safe during a storm. 

Therefore, before you get to other safety measures, the first thing you should do is ensure that everyone has their life jackets on, or any foul-weather gear you may have on board. Doing so prepares you adequately for the storm, reducing the risks of drowning or falling overboard.

While some life jackets come with harnesses attached, others don’t. As such, it is highly advisable to have your harnesses attached to your boat’s cleats or tie off to ensure they’re readily available when needed. 

3. Have Your Emergency Equipment On Standby

Reaction is everything when caught in a severe storm. And the best way to respond to the threat of an imminent storm is to have all your safety and emergency equipment on standby. 

Therefore, as you’re issuing out life jackets and having crew members and passengers wear harnesses, it’s best to assemble all the essential safety equipment before moving on to other steps. 

Some of the vital emergency equipment to assemble during a storm include first aid kits, bailers, bilge pumps, throwable floatation devices, and signaling devices. 

It’s also a good idea to prepare a life raft (if you have one) and perhaps stock up on some emergency supplies like food and water.

4. Stow Unneeded Accessories or Gear 

Things can get pretty rough during a storm, and the best way to reduce the risk of object/accessory-induced injury is to store them safely. 

Tumbling objects, whether heavy or light, can have a massive impact on the survival rates of people aboard a boat. As such, you should store them somewhere safe where they won’t be thrown around by fast-paced winds. 

Be sure to secure accessories below or above your boat’s decks, depending on its design. While you can stow small items and gear like fishing rods and grills, it’s usually best to latch down the heavy ones, as moving them around can affect your boat’s balance. 

5. Close All Windows and Batten Down Hatches

Another vital point to remember when caught in a storm is to secure your boat by closing down all doors, windows, and ports to keep the water out. 

Failure to close windows, latches and hatches increases the chances of flooded cabins – and you don’t want that, as a flooded cabin means your boat will be at a heightened risk of flooding. 

It’s also at this time that you should remove all canvas like awnings, dodgers, biminis, and mainsails to reduce windage. You should also take down items like flags and cushions to ensure the wind doesn’t have any surface to blow and destabilize the boat. 

6. Disconnect Power Cords and Avoid Metallic Items 

With storms also comes the increased risk of lightning strikes. To be on the safe side, you should disconnect power cords to protect your electrical equipment and, even more importantly, eliminate the risk of electric shock while navigating past the waters.

You should also steer clear of VHF radios and keep away from metallic parts of the boat, including the railing and even metallic steering wheels. Rubber gloves will come in handy if your boat uses metal steering wheels, as they’re non-conductors. 

And since the risk of lightning strikes will be higher when using open boats, everyone on board must remove jewelry or any metallic items that might increase the risk of strikes. For open boats, crew members and passengers will need to lie as low as possible to reduce the chances of lightning strikes. 

7. Drive Slow 

Broaching is a common issue that occurs during storms, and the best way to avoid it is to drive slowly . The trick when navigating past strong tides is to slow down such that the water outruns your boat. 

Therefore, when caught in a storm, try to slow down gradually to avoid destabilizing the boat. Driving slowly allows you to have better control of your vessel while cruising past stormy waters. 

Additionally, you should also try to hit the waves at a 45-degree angle when sailing during a storm. Maintaining the 45-degree angle of attack ensures your boat’s propellers stay below the water, allowing for a less turbulent ride. 

Take a look at our article on : What Should You Do To Avoid Colliding With Another Boat? (Safety Tips)

8. Head Toward Safety

Maintain a slow pace as you move towards the shores. While it might be tempting to speed up to outrun the waves, maintaining a slow speed is your best bet to reaching back to land safely. 

At times, waiting out the thunderstorm might be your best bet, especially when dealing with tons of lightning strikes. Staying inside the cabin is highly recommended (avoid touching electrical or metal items), but staying low to the deck might be your only option when dealing with open boats. 

Should you choose to ride the storm out, move towards a local dock or port with your navigation lights turned on. Remember to maintain a 45-degree angle when approaching waves to keep the vessel stable. 

Finally, be sure to keep a close eye on floating debris, other boats, and obstacles that might be on your route. 

How To Prepare Adequately For A Storm

Check the marine weather updates.

The best way to prepare for a storm is to avoid it, and what better way to stay safe than checking the weather forecast (marine)? The National Weather Service usually provides useful information about inclement weather and potentially useful general warnings. 

The weather service usually provides vital details, from hurricane warnings to tropical storm warnings, special marine warnings, and gale warnings. You can also benefit from regular small craft advisories that provide warnings for people with small vessels. 

Invest in Lightning Protection Systems

Although not all boat owners prefer investing in lightning protection systems, doing so might help you save thousands of dollars in repairs and medical attention. 

A good lightning grounding system will help eliminate the risk of electrical surges and shocks caused by lightning strikes. These systems work by dissipating the volts resulting from lightning strikes into the water as opposed to your boat, effectively neutralizing the effects of electrical surges. 

Always Pack Up Your Emergency Equipment Or Supplies

Another effective way to prepare for storms is to prepare emergency supplies . This rule applies to all mariners, regardless of skill level, as you never know when tragedy will strike. 

Have enough supplies, from life jackets to floaters, manual hand pumps, fire extinguishers, tool kits, and raincoats. A well-stocked first aid kit is also crucial regardless of how long you intend to sail. 

Life preservers, safety harnesses, a functional radio, and approved United States Coast Guard (USCG) supplies should always be on board before sailing. 

Wrapping Up

Staying safe when boating should always be your top priority, no matter your level of experience. 

And since storms are highly unpredictable, it’s always best to plan adequately for in-storm scenarios. 

Below are important things to keep in mind when navigating past a storm in your boat:

• Assess the intensity
• Ensure every crew member or passenger have their life jackets on
• Have your emergency equipment on standby
• Stow unneeded accessories or gear 
• Close all windows, latches, and hatches 
• Disconnect power cords

Heavy weather tactics: 5 options for sailing through a storm.

• Do you have enough sea room to allow the boat to crab slowly to leeward? The answer will obviously vary depending on your distance shore, the direction of the wind/current, and the longevity of the storm conditions. Remember, heaving-to is a passive tactic, so you’ve got to be o.k. with letting the boat do its thing while you hunker down in the cabin.
• Are your sails and rigging up to the task? As with many storm tactics, your sails and rigging will be subjected to high loads and chafe. Is your boat equipped with storm sails that can handle strong winds and potential flogging? Our boat's sails wouldn't be up to the task of remaining hove-to for hours on end, but I'm confident that I could ride out a short summer squall. 
• How well does your particular boat heave-to and will it remain hove-to without putting your beam to the seas? Large swells and breaking waves can be trouble for a boat that doesn’t like to heave-to.
• Do you have sea room to run off? That is, is there land, shallow water or other dangers downwind of your position that make this tactic unadvisable? Furthermore, will running off simply serve to keep you in the path of the storm longer than an alternative tactic? 
• Can you maintain steering with the wind and waves on your stern quarters or directly abaft?
• Do you need to deploy a drogue or warps to slow your forward speed in order to maintain control and keep from being overpowered by the waves?
• Are you up for the physically exhausting challenge of manually steering your ship for potentially hours or days on end?

Lots of great advice and references in there, thanks for all the helpful tips! We were caught in an unexpected gale in the Gulf Stream this year with winds sustained out of the north averaging 45 knots for a good 90 minutes. We were running off under bare poles until the winds subsided to the mid 30's, but it worked out well for us.

Thanks Jessica. That's exactly the kind of real world experience I was hoping folks would share in the comments.

We were in a big storm in Stewart Island - New Zealand - getting blown on to a lee shore. We tried to start the motor to help us crab to windward, but in one knock down the motor must have got a big gulp of air instead of diesel. Anyway it meant that the motor cut out. So if you do try and use your motor to assist, make sure you have got a full tank of fuel.

Concerning lying a-hull, it's interesting to read Alan Villiers's account of using this tactic with the Mayflower-II during her crossing in 1957. He wrote "we had no idea what would happen,as no one had attempted this in a ship of this type in over 200 years..." He went on to note that with the sails down, and the rudder lashed to leeward, she pointed up nicely and "lay as a duck on a pond with her head tucked under her wing." (I'm paraphrasing here, since I can't find my copy of Men Ships and the Sea at the moment...) Its' worth noting that ships of that type, with their huge, boxy top-sides had substantially different windage characteristics than our sleek modern designs. From what I've been able to glean, lying a-hull in a square-rigged galleon 300 years ago probably wasn't a terribly different proposition than heaving to under a back-winded jib today.

I should have added that as I understand it at least, it was a maneuver designed to keep the waves on your stern quarter. Same principles, just facing a different direction? I'm gonna have to find my copy of that darn book now, as I'm confusing myself and sounding like an idiot.

Thanks for your wonderful and so helpful tips. We also would like to invite you to our Sailing Community - Clubtray Sailing Clubtray Sailing where members could be more helpful by your great advices and references. Hope to read more kind of real world experiences from you soon.

What to do in a Lightning Storm on a Boat

• By Mike Telleria
• Updated: February 10, 2020

Powerful, dangerous, highly unpredictable — all are common descriptions of lightning storms. A direct strike that results only in ringing ears and a few roasted electronics would be considered lucky. Unlucky would be through-hulls blown out, a sunk boat or worse — possibly serious injury or death.

Many powerboaters like to think that they’ve got the speed to simply outrun or get out of the way of lightning storms , or they figure they’re safe if they go boating only when it’s clear and sunny. That’s an attitude aided by the low odds of a boat being struck by lightning, which BoatU.S. pegs at about one out of 1,000 boats in any given year.

No worries, right, mate? Wrong.

Engines can malfunction ; big lightning storms can leave no room to escape; sunny mornings can turn into dark, threatening afternoons. If yours is the only boat in the area during a lightning storm, the odds of being struck go way up, leaving you and your crew vulnerable to millions of volts raining down from the skies. Lightning and boats do not mix. While manufacturers can build in a degree of protection, lightning protection begins with boaters being informed and prepared to act in the event of a thunderstorm or actual strike. You should know the following techniques and strategies.

Boating in a Thunderstorm is Bound to Happen at Some Point

A strategy of boating only on sunny, cloudless days may work well in places like Idaho and California, but that would mean almost never using the boat in places such as Florida, Louisiana and much of the Midwest. For example, most of Florida — the Sunshine State — has at least 70 to 80 thunderstorm days per year, with some parts having more than 100 thunderstorm days per year (with increased activity during the summer months).

Absolutely, boaters should track VHF , Internet and television weather reports and make responsible decisions about whether to go boating depending on the likelihood of lightning storms. Short-term forecasts can actually be fairly good at predicting bigger storms, but small, localized storms might not be reported. This is when knowing how to read the weather yourself can come in handy. (The U.S. Power Squadrons offers great weather courses for boaters, and there are many books that cover the basics.)

Lightning strikes typically occur in the afternoon. (Florida estimates 70 percent occur between noon and 6 p.m.) A towering buildup of puffy, cotton-white clouds that rise to the customary flat “anvil” top is a good indication to clear the water and seek shelter — or move out of the storm’s path if possible. That’s if the storm is at least somewhat off in the distance (most storms are about 15 miles in diameter and can build to dangerous levels in fewer than 30 minutes). If lightning and thunder are present, just count the seconds between the lightning and corresponding thunder and then divide by 5 — this will provide a rough estimate of how many miles away the storm is.

A storm that builds directly overhead might be less obvious until those pretty white clouds that were providing some nice shade moments ago turn a threatening hue of gray as rain dumps on you and the wind starts to howl or, worse yet, boom with thunder and lightning that are right on top of each other. Now is the time for a mad dash to the dock and shelter if close by. Like the National Weather Service says: “When thunder roars, go indoors!” You really don’t want to be on a boat struck by lightning. If out on open water or too far from shore and shelter, it’s time to hunker down and ride it out.

Caught in Thunderstorm on a Boat

Boaters who have been struck by lightning often begin their stories with “I was caught in this storm … ” before they share their miraculous or harrowing tales of survival and destruction (BoatU.S. has a number of first-person storm stories archived online: boatus.com/seaworthy/swthunder). Even though getting caught in a storm is not always avoidable, there’s still plenty that boaters can do to minimize the chance of a strike and lessen injury and damage if there is a strike.

How to Stay Safest in a Thunderstorm

We all learn in grade school that it is not safe to be outside during a lightning storm. We also learned that lightning seeks the highest point, and on the water that’s the top of the boat — typically a mast, antenna, Bimini top, fishing rod in a vertical rod holder or even the tallest person in an open boat. If possible, find a protected area out of the wind and drop anchor . If the boat has an enclosed cabin, people should be directed to go inside and stay well away from metal objects, electrical outlets and appliances (it’s a good idea to don life jackets too). Side flashes can jump from metal objects to other objects — even bodies — as they seek a path to water.

A Microwave Oven is a Faraday Cage

Lowering antennas, towers, fishing rods and outriggers is also advised, unless they’re part of a designated lightning-protection system. Some boaters also like to disconnect the connections and power leads to their antennas and other electronics, which are often damaged or destroyed during a strike or near strike.

Under no circumstances should the VHF radio be used during an electrical storm unless it’s an emergency (handhelds are OK). Also, be careful not to grab two metal objects, like a metal steering wheel and metal railing — that can be a deadly spot to be if there’s a strike. Some boaters opt to steer with a wooden spoon and keep their other hand in a pocket if forced to man the helm during a storm, while others like to wear rubber gloves for insulation.

Surviving Lightning Strikes While Boating

An open boat like a runabout is the most dangerous to human life during lightning storms, since you are the highest point and most likely to get hit if the boat is struck. If shore is out of reach, the advice is to drop anchor, remove all metal jewelry, put on life jackets and get low in the center of the boat. Definitely stay out of the water and stow the fishing rods.

If all goes well, the storm will blow past or rain itself out in 20 to 30 minutes. It’s best to wait at least 30 minutes until after the last clap of thunder to resume activities.

There’s a Zap For That

What to do when your boat is struck by lightning.

Knowing what to do in a storm and having the best lightning-protection system installed on the boat is by no means a guarantee that lightning won’t strike. The immediate checklist for a direct hit is very short:

1. Check for unconscious or injured persons first. If they’re moving and breathing, they’ll likely be OK. Immediately begin CPR on unconscious victims if a pulse and/or breathing is absent — there’s no danger of being shocked by someone just struck by lightning.

2. In the meantime, have someone check the bilges for water. It’s rare, but lightning can blow out a transducer or through-hull — or even just blow a hole in the boat. Plug the hole, get the bilge pumps running, work the bail bucket — whatever it takes to stay afloat. An emergency call on the VHF is warranted if the situation is dire. If the radio is toast, break out the flare kit.

If there are no injuries and no holes or major leaks below, just continue to wait it out. Once the danger has passed, check the operation of the engine and all electronics. Even a near strike can fry electronics and an engine’s electronic control unit, cutting off navigation, communication and even propulsion. Some boaters stash charged handheld VHF and GPS units and a spare engine ECU in the microwave or a tin box for this very reason. These makeshift Faraday cages have saved equipment.

One in 1,000 Boats Are Hit by Lightning Per Year

Obvious damage will need to be assessed and set right. Even those lucky enough to come away completely unscathed after lighting storms, with no apparent damage should have a professional survey done just to be sure. Minor damage to through-hulls can result in slow leaks, and all manner of electrical wackiness can emerge — sometimes much later. It’s best to catch these issues right away and get that information to the insurance folks for coverage.

Is Just a Ground Plate Enough?

On many levels, robust insurance coverage plays a huge role in your lightning-protection plan. Knowing how to avoid lighting storms and read the weather are certainly important, being ready for action in the event of a storm or strike is crucial, and an upfront investment in lightning protection can lessen destruction. When it comes to dealing with the aftermath of a damaging strike, however, extensive lightning strike coverage can’t be beat.

Take it from a luxury trawler owner who sustained more than $1 million in damage from a strike: “Boat insurance turns out to be the best investment we have made in the past 10 years!” he said. “We will never again grumble about writing a check for an insurance premium.”

How To Help Your Boat Survive A Major Storm

Hurricane Gloria was a most impolite lady. She barreled up the Atlantic coast, scaring the heck out of people from Florida to Massachusetts. Despite the fact that the storm didn’t live up to its billing, hundreds of boats in New York, Connecticut, Rhode Island, and Massachusetts were destroyed or severely damaged. In some cases, the boats were lost through no fault of the owner. No amount of preparation will save your boat if another boat drags down on it in the middle of a hurricane.

In other cases, however, lack of proper preparation was a major cause of a damaged boat. There’s no excuse for that type of loss.

Despite the fact that modern forecasting methods are far from perfect, a large storm such as Gloria almost always is tracked with enough precision to let you know if you’re potentially in the path of destruction. With a day or more of warning, you have plenty of time to take the precautions necessary to give your boat the best chance to survive a major storm.

When the load exerted on a boat’s ground tackle-whether a mooring or her own anchors-exceeds the holding power of the ground tackle, the boat will drag. One of the primary contributors to that load is the windage of the boat.

If your boat hung perfectly head to wind, the windage loading would be fairly small, consisting of the frontal area of the hull, deck structures, spars, and rigging in the case of a sailboat, and the hull, deck structures, bridge, and antennas of a powerboat. Unfortunately, few boats lie perfectly head to wind through a storm. Instead, they yaw about from side to side. As the boat sails around on her anchors or mooring, the total area presented to the wind, and hence the total loading on the ground tackle, varies dramatically. The area presented by any boat broadside to the wind is several times that presented by the same boat when it is perfectly head to wind. Since the change in wind loading is a function of the square of the wind velocity, the strain on your ground tackle increases geometrically as the boat yaws around. Reducing windage will help reduce the total loading, and hence help your boat stay put.

You can substantially reduce the windage of any boat with only a few hours of work. First, remove Bimini tops, cockpit dodgers, spray curtains around cockpits, and awnings. Those are pretty obvious. The rest may not be.

Sails should be removed, particularly roller furling headsails. You don’t just have to worry about the windage of the rolled-up sails, you have to worry about what will happen when the sail unfurls. And we practically guarantee it will, no matter how well tied it may be. Mainsails should be removed for the same reason. If the sail is so big that you can’t handle it yourself, and you have no one to help, add extra sail ties, and thoroughly and tightly lash down the sail cover. The normal securing system of the sail cover, and the normal amount of sail ties used, is not adequate to hold the sail in place during a major storm. If the sail gets loose, it will at least flog itself to death. At worst, it will add enough windage to make your boat drag its ground tackle.

Take off man overboard gear, cockpit cushions, cowl vents, antennas, and halyards, if the halyards can be rerove easily. Internal halyards can be run to the masthead, leaving a single halyard led to deck to allow you to retrieve the others after the storm. No matter how well you tie them off, halyards will flog hell out of your spars, in addition to being more windage. Likewise, masthead instrumentation may simply blow away, particularly your anemometer cups.

Get it Off the Boat

It’s a good idea to take everything that isn’t bolted down off the boat entirely. If a boat does go ashore, it’s a sad but true fact that vandals may make short work of her. Electronics, clocks, barometers, books, navigation gear may all vanish. If you value it, take if off the boat. Chances are that no insurance policy will cover you completely enough to make up for the loss of valuable gear.

Know Your Ground Tackle

Is your mooring really a 1000 pound mushroom with 3/4 ” chain? It may be worth hiring a diver to find out, preferably before a storm threatens. Likewise, all shackles, chains, and mooring pennants should be examined at least once a season to make sure they are in good shape. If the condition of any component of the system is questionable, replace it. If your insurance adjuster sees a corroded through piece of chain or a mooring pennant that is badly worn, he may well be reluctant to approve your claim in case of loss.

In crowded harbors, permanent moorings may lack adequate scope to deal with the high tides associated with storm conditions. It may be possible to increase scope for a storm by replacing or lengthening the mooring pennant. Just as with an anchor, the holding power of a permanent mooring is increased by additional scope.

Some moorings are equipped with large, inflatable surface buoys. The positive flotation of these buoys may reduce the holding power of the mooring in extreme high tides, so it may be worth removing the buoy before a storm; just don’t forget to replace it before casting off the mooring pennant after the storm is over.

At the Dock

As a rule, boats tied to docks are at greater risk than boats kept at moorings or on anchors. Floating docks are rarely strong enough to take the loads exerted on them by boats in storm conditions. In addition, if the tides are extremely high, floating docks may simply float off the pilings which hold them in place.

A boat kept at a dock can’t weathercock (face into the wind) as storm winds change direction. Therefore, the boat at a dock almost always presents more windage than a boat secured to moorings or anchors that is free to swing head to wind.

If your boat must be kept at a dock in a storm, secure the lines to the pilings, rather than to the floating docks. It is best to tie the lines high on the pilings, so they will not be chafed if the docks ride up on the pilings. Instead of using loose bowlines around the pilings, use multiple clove hitches, or a clove hitch finished with two half hitches. That way, the lines will tighten on the pilings, and are unlikely to pull off even if the pilings go under.

Anchored Out

If you have good ground tackle and a good mooring won’t have to worry about crashing into docks, or docks crashing into you. What you will have to worry about is other boats with less adequate ground tackle dragging down on you, either damaging your boat or straining your own ground tackle so much that your boat drags.

The first rule of thumb when anchored or moored during a severe storm is to get out as much ground tackle as possible. You may have a good permanent mooring, but if you back it up with your own anchors, you’re going to have an even better chance of survival.

Usually, it is possible to forecast the likely direction of the strongest winds, even with a hurricane whose exact path is unknown. A good rule of thumb is to deploy your heaviest anchor in the expected direction of the strongest winds, and your second anchor 180 ’ from that. You may want to put your primary anchor upwind of, and at a 45 ’ angle to, the mooring, so there will be less likelihood of chafe between your anchor rode and your mooring chain.

When putting out your anchors, get them as far from the boat as your rodes will allow, leaving yourself perhaps 25 ‘ of line on deck to make adjustments after the anchors are down. The more scope you have out on the anchors, the better they will hold. All anchors hold best when the pull on them is perfectly horizontal. You may increase the holding power of an anchor by 25 % by increasing the scope from 5:1 to 1O:1.

Remember that your biggest anchor does not necessarily have the most holding power in a particular bottom. If you’re anchored in soft mud, a Danforth will have much more holding power than a kedge anchor of the same weight.

Line chafe has probably caused the loss of more boats than any other single factor. Whether you’re moored out or at the dock, your lines must be protected from chafe.

No matter how well polished your bow chocks are, they’re still metal, and are harder than your lines. In a storm lasting several hours, even the smoothest metal fittings will start to wear away your lines. Chafing gear can be made from almost any sacrificial material. Canvas and leather are the traditional materials used, but “sticky dacron” sail repair cloth or even old towelling or T-shirts will do. Old denim blue jeans cut in strips make exceptionally good chafing gear.

Chafing gear won’t do any good if it won’t stay in place. The best chafing gear is undoubtedly leather sewn over the lines, but if you’re preparing for a storm, it’s too late to be elegant. Duct tape-plenty of it-will do in a pinch.

You can also tie the chafing gear on with light nylon, but it, too will chafe.

Chafing gear should cover more of the line than you think will come into contact with a chafing hazard, to allow for fine tuning the lines, to compensate for stretch, and to make up for the fact that the chafing gear may slip under load. In addition, if you are aboard your boat during a storm, you may want to ease out a foot of line now and then to shift the location of chafe slightly.

Whenever possible, key dock lines should be doubled. If one fails, you want a backup. The only danger here is that the deck can quickly become a rat’s nest. In addition, those elegant little cleats may suddenly be too small to take two 3/4” dock lines. It is absolutely impossible for a boat to have cleats that are too large, just as it’s impossible to have anchors that are too big. All it takes is one storm to convince you of that.

Whenever possible, lead heavily loaded lines to winches before belaying them on cleats. Winches are likely to have more fastenings, distributing their load over a larger area of deck. Distributing the loads between a winch and a cleat can be a tricky business. Normally, when using a winch you take three turns around it, so that almost all the load is carried by the winch. Using only one or two turns on the winch allows more load to be carried by the cleat.

Don’t carry a lot of heavily loaded lines to a single cleat. That’s like putting all your eggs in one basket. If the cleat goes, the boat goes. This is when multiple cleats on the bow pay off. You can lead each anchor or mooring line to a separate cleat, not only making it easier to adjust individual lines, but distributing loads better.

Through bolted cleats are designed to be loaded in sheer; that is, with the load parallel to the cleat and perpendicular to the fastenings. When the load becomes a tension load-vertical to the fastenings-you’re headed for trouble. Watch the leads of lines carefully to load hardware properly. Sometimes, a strong snatch block can be used to deflect loading to a better angle, or to reduce chafe. For storm-induced loads, don’t use a block to change a lead more than about 45 ‘. You’re likely to induce loads on the block or its point of attachment that it just can’t handle.

Lines may well pop out of open bow chocks as the boat pitches. It may be possible to lash lines into chocks by passing a light line under the bow or to adjacent hardware. Closed chocks work better, but once again you have to watch the direction of loading. Closed chocks are designed to be loaded downward, not upward. If you put a tension load on the chock’s fastenings, they may pull out of the deck.

Obviously, the strength of your deck hardware is extremely important, and the time to check it out is before there is a danger of storms. Proper backing plates, proper bolts, and strength of the deck and the fitting itself are critical. Winter is a good time to crawl around under the deck to check these things out. You’ll sleep a lot easier knowing just how hardware is attached.

Hauling Out

Usually, boatyards are overwhelmed with frantic calls from owners to haul their boats before a hurricane. Hauling may or may not be a good idea. Hauling a boat and leaving the mast in is an invitation to disaster. Hauling at a yard that is only a few feet above water level also may gain little. Putting the boat inside a shed that may blow down also gets you nothing.

By all means, if your boat is trailerable, get it out of the water. Tow it to high ground, but don’t park it under a tree!

On or Off the Boat?

If your boat is on an anchor or mooring, you may increase its chances of survival by staying on the boat. You may be able to fend off a boat dragging down, adjust a critical line, take the load off the ground tackle by running the engine. You also increase your chances of getting killed or injured. Boats are replaceable; people are not.

There is no easy answer to this one. Few things are more heartbreaking than watching another boat chafe through your anchor lines while you’re helpless on the shore. Few things are more terrifying than being aboard a boat that is dragging down to destruction on a granite seawall that towers over your head.

Should You Move Your Boat?

One of the most basic questions is whether your boat should be moved to another harbor. Most regions have protected anchorages known as hurricane holes. The only problem is that usually these are known to everyone, and may become so crowded when a major storm threatens that they become more dangerous than a more exposed anchorage.

Moving to a hurricane hole early is no guarantee of safety. You may get the best spot, but there’s no way to keep someone from anchoring right on top of you. If you think all boat owners are a generous and gentlemanly bunch, you haven’t seen them in time of stress when their boats are endangered.

You must realistically assess your chances for survival wherever you are. If strong southerlies are forecast in a harbor whose north end is a stone wall, you’d better think about moving elsewhere, or at least moving as close under the weather shore as is practical. Don’t forget to allow for changes in wind direction, however.

The wind itself is usually less of a problem than high tides and waves which reduce scope and increase chafe as the boat surges. If you’re behind a seawall which is only 5 ‘ above mean high water, a storm which comes at high tide is likely to submerge the breakwater, exposing you to the full force of wind and waves.

Use common sense. Try to imagine what will happen to docks, pilings, seawalls, and the other boats around you. What happens when the wind shifts? What if the docks come loose? Don’t move your boat until you have a coherent plan, and only if you can say with confidence that the place you have chosen is better than the place you are. An exposed location with a bottom that has good holding characteristics may be better than a protected location with lousy holding, if you have adequate ground tackle.

If you’ve done all you can to secure the boat-reducing windage, removing valuable gear, putting out extra lines, chafing gear, anchors-then you have done all that is reasonable to ask to prepare your boat to meet a storm in port. Get off the boat with a clear conscience, but try to stay as close as possible during the storm, as long as you don’t risk your life. If your boat does come ashore, you may be able to reduce damage or prevent vandalism if you’re close at hand. We have no sympathy for those who call the boatyard a few days after a storm to find out if their boat has survived.

One last thing to do is to take pictures of your preparations. If your insurance company questions the loss of your boat, it helps to have pictures of how you’ve prepared her. It may also help to prove a loss.

Mentally preparing for a storm in port is a lot like thinking about your emergency equipment. It may be unpleasant to think you’ll ever need it, but if you do, it’s nice to be familiar with how it works and what it can do. Careful preparation of your boat won’t guarantee its survival, but it will give it a far better chance.

Complete Guide to Storm Sails

Last Updated by

Daniel Wade

June 15, 2022

Storm sails are popular safety measures that help you retain control of your boat in high winds. They also reduce the risk of knockdown.

In this article, we'll cover the most common types of storm sails and their uses. Additionally, we'll go over storm sail materials, cost, sizing, and tips from the sailing community. You'll also learn when (and how) to deploy storm sails at sea.

Storm sails are durable and compact sails designed for use in rough weather. They're smaller than regular mainsails and headsails. The most common kinds of storm sails are the trysail and the storm jib. Storm sails can be deployed alone or in pairs.

The information contained in this article was sourced from expert sailors and storm sail manufacturers. Additionally, we sourced technical specifications from reviewers and users of storm sails.

Table of contents

What are Storm Sails?

Storm sails are small and durable headsails and mainsails designed for use in rough weather. They are a fraction of the size of typical mainsails and headsails, and they attach to the vessel using a multi-point tie system.

Storm sails are almost always triangular regardless of what kind of vessel they're deployed on, which includes storm sails designed for gaff-rigged sailboats. This is because a three-pointed sail is durable and easy to deploy at the base of the mast. Three connection points are easier to deal with than four, and storm sails don't require the use of top spars.

Storm sails are typically bright orange in color to distinguish them from other canvas aboard the vessel. Additionally, high visibility material makes it easier to see the boat in dangerous conditions. This is especially useful in emergencies, and it helps avoid collisions with other vessels.

Storm sails are stronger than the rest of the sails aboard most vessels. They are designed to stand up against gale-force winds and heavy ocean spray. Most storm sails can be deployed rapidly without completely removing the mainsail or headsail.

How do Storm Sails Work?

The concept and function of a storm sail is simple. A storm sail is essentially just a reefed version of your headsail or mainsail. Storm sails provide propulsion in high winds, which is essential if you want to keep control of the boat.

Storm sails are useful because they are smaller than the smallest configuration of your typical sail setup. In other words, they give you a smaller sail plan than you could have achieved by reefing. During dangerous storm conditions, this could be the difference between a controllable boat and a knockdown.

Types of Storm Sails

Most vessels that carry storm sails have one for the forward sail plan and one for the after sail plan. This typically includes a trysail for replacing the mainsail and a storm jib for replacing the headsail. In some cases, vessels opt to carry only a single storm sail as an easy precautionary measure.

Vessels that only carry a single storm sail generally opt for a storm jib, as it can be easier and safer to rely on a headsail during foul weather conditions. Additionally, it frees up the mainsail for precise adjustments, as it's easier to reef and trim from the cockpit. The downside of carrying only a storm jib is that it requires someone to trek to the bow of the boat during hazardous conditions.

In addition to trysails and storm jibs, there are many sub-varieties of storm sails available today. Next, we'll cover a few of the most popular storm sail types and their intended uses.

Basic Storm Sails for Emergencies

Basic no-frills storm sails are available for typical cruising boats to use in emergencies. These simple, often brightly colored Dacron sails are easy to rig and compact for long-term storage. They are triangular and often flat, which makes them ideal for quick deployment.

They are the most affordable type of storm sail and often considered 'universal fit' for boats within a certain size range. In other words, you probably won't have to custom-order a basic storm sail setup for your production fiberglass cruising sloop.

Basic storm sails often come in a convenient and weatherproof storage box that's clearly marked for stowing with your other emergency gear. These are not the most efficient or durable storm sails available, but they're strong enough to improve your chances in a dangerous situation.

Racing Storm Sails

Storm sails have found a unique niche amongst some offshore racing sailors. Vessels that participate in offshore regattas in foul weather often rely on them to achieve high speeds. This is especially true in conditions that are too hazardous to deploy a standard sail plan.

There are not a whole lot of purpose-built storm sails for racing. However, many sailors who participated in ocean races choose higher-quality and more controllable storm sails. That said, ocean racers often choose storm sails with unique shapes and characteristics.

Racing storm sails are usually slightly larger than basic emergency storm sails. They often have a deeper reef and longer leech, which increases the size of the canvas and brings it closer to the deck. Additionally, these characteristics make the small sail more efficient and allow the vessel to reach higher speeds while retaining precise control.

Racing storm sails are often reinforced in key areas, which is done at the factory or after the fact by the owner. This is because they're more likely to be deployed more than once and left on extended periods. Sometimes, Racers opt to delete unreliable quick-rig features that are found on standard storm sails.

Custom Storm Sails

There are many reasons why a sailor might choose to have a custom storm sail produced. As far as cost is concerned, it's comparable to a typical custom sailmaking job. Custom storm sails can be made with unique dimensions to optimize their efficiency on a specific hull design.

Custom storm sails are sometimes produced with higher-quality materials than consumer models, which gives sailors additional peace of mind. In many cases, the unique design of some sailboats requires purpose-built storm sails.

Most sailmakers will produce storm sails upon request. However, you may have to provide additional specifications ahead of time. They can also reinforce consumer storm sails using high-quality material or make adjustments to provide a better fit for your boat.

What are Storm Sails Made Of?

Storm sails need to be strong and weather-resistant. Additionally, they need to survive long periods of storage in less-than-ideal conditions, such as in the bilge or under a deck hatch.

Modern sale materials such as Kevlar and laminates are strong, but they don't always perform well in long-term storage. As a result, storm sails are typically made with a thick sheet of good old Dacron.

Dacron is a popular type of polyester sail fabric that's found in all kinds of sailboats. The primary difference between a Dacron storm sails and run-of-the-mill sail fabric is color and thickness.

When to Use a Storm Sail

What sort of conditions warrant the use of a storm sail? This varies between boats, and also between captains and crews. But generally speaking, storm sails can be deployed in high-wind conditions when typical reefing and adjustments aren't enough.

The precise wind speed that causes you to deploy storm sail is impossible to predict without knowing your specific vessel's handling characteristics. However, storm sails are sometimes found in winds exceeding 30 or 40 knots.

If a knockdown is imminent, the best course of action is most likely maneuvering. It will be very difficult to rig a storm sail when the vessel is at extreme risk of being blown over. It's best to rig a storm sail when the boat is still under control, either by you or someone else.

How to Rig a Trysail

Storm sails rig up similarly to your regular sails. Precise installation instructions vary between boats and sail models, but you can expect to install them roughly the same way.

The luff and tack of the main storm sail (trysail) typically rig up using sheets to the spinnaker blocks on the mast. The storm sail sheet runs to a block on the deck and then to a winch, similarly to how a jib sheet would run.

How to Rig a Storm Jib

The storm headsail, or storm jib, rig up using an inner forestay or halyard. The storm jib is hanked on, and the jib sheet runs to block and winch on the deck. The storm sheet typically follows the same route as a regular job sheet.

Are Storm Sails Required?

Some sailors believe that the Coast Guard requires storm sails aboard all sailboats. This is not the case, as the USCG doesn't list storm sails on its roster of mandatory safety gear . The majority of sailboats don't (and probably won't ever) have a storm sail aboard.

While storm sails are not a legal requirement aboard sailboats, there are situations where sailors must carry them. Ocean races are an example of one such situation, as many offshore regattas mandate them. This is especially true in Northern latitudes, where rough weather and gale-force winds are commonplace. Most of these organizations don't require sailors to use them; they just require sailors to have them.

How Much do Storm Sails Cost?

Storm sails are typically affordable, at least compared to other emergency gear, such as automatically inflating lifeboats. Storm sail prices vary based on material quality, thickness, and size. Below, we'll cover the price and specifications of a typical storm sail as an example.

Our example model from National Sail and costs $640 . It's a conventional hank-on storm jib, which is the most common type. It has a luff of 28 inches, a leech of 22.5 inches, and a foot of 11.9 inches. It has an overall weight of 9 pounds. Based on its size, this model is designed for a boat around 40 to 50 feet in length.

As you can see, storm sails are relatively affordable, even for large boats. The prices you can expect to pay for a typical 30-foot cruising vessel are between $200 and $350, depending on the quality and thickness of the cloth.

Storm Sail Sizes

It's essential to find the right size storm sail for your boat. Storm sails vary in both dimensions and fabric weight (or material thickness). Most storm sail manufacturers produce trysails and storm jibs for vessels between 20 and 60 feet in length.

Are Storm Sails Necessary for Offshore Cruising?

The debate about the necessity of storm sails has been raging for years. The jury is still out whether sailors should keep one aboard. Some people swear by them, and others dismiss them as a needless complication when reefing and handling would suffice.

It comes down to your personal experience and judgment. Storm sails work, and there are many instances where they've been deployed and likely helped save vessels from knockdown or foundering.

That said, sailors rightfully note that they can be very difficult (and even dangerous) to deploy during storm conditions when captain and crew effort would be more useful trying to handle the vessel.

Storm Sail Use and Preparation

It's essential to practice with storm sails in windy conditions before relying on them in truly dangerous situations. Go out on a windy day and practice deploying and controlling your storm sails. Put a plan in place to get them up quickly and safely.

Make sure to wear a life jacket and harness when deploying storm sails or moving around the boat in rough weather. Ensure that you have a place to attach your harness along the way, especially in areas that you need to stand to rig your storm sails.

Also, make sure to find harness attachment points on both sides of the mast, as you never know what side the boat will be heeling when you need to deploy your storm sails. Once you're confident that you can deploy and control your storm sails quickly and safely, you'll be ready to rely on them as an additional safety measure in rough weather.

Should I Buy Storm Sails?

So, should you buy a set of storm sails? Again, the answer depends on your location, sailing conditions, and personal experience. If you live in an area where rough weather is common or if you intend to embark on an offshore race, it's worth considering a set of storm sails. For the price, storm sails are a cheap insurance policy for hazardous weather.

Sailing in lightning: how to keep your yacht safe

• In partnership with Katy Stickland
• July 22, 2022

How much of a concern is a lightning strike to a yacht and what can we do about it? Nigel Calder looks at what makes a full ‘belt and braces’ lightning protection system

Storm clouds gather at Cowes, but what lightning protection system, if any, does your boat have for anchoring or sailing in lightning? Credit: Patrick Eden/Alamy Stock Photo

Most sailors worry about sailing in lightning to some extent, writes Nigel Calder .

After all, going around with a tall metal pole on a flat sea when storm clouds threaten doesn’t seem like the best idea to most of us.

In reality, thunder storms need plenty of energy, driven by the sun, and are much less frequent in northern Europe than in the tropics.

However, high currents passing through resistive conductors generate heat.

Small diameter conductors melt; wooden masts explode; and air gaps that are bridged by an arc start fires.

On boats, radio antennas may be vaporised, and metal thru-hulls blown out of the hull, or the surrounding fiberglass melted, with areas of gelcoat blown off.

Wherever you sail, lightning needs to be taken seriously.

Understanding how lightning works, will help you evaluate the risks and make an informed decision about the level of protection you want on your boat and what precautions to take.

Most lightning is what’s called negative lightning, between the lower levels of clouds and the earth. Intermittent pre-discharges occur, ionising the air.

Whereas air is normally a poor electrical conductor, ionised air is an excellent conductor.

These pre-discharges (stepped leaders) are countered by a so-called attachment spark (streamer), which emanates from pointed objects (towers, masts, or lightning rods) that stand out from their surroundings due to their height.

Summer is the season for lightning storms in the UK. Here, one finds early at Instow, Devon. Credit: Terry Matthews/Alamy Stock Photo

This process continues until an attachment spark connects with a stepped leader, creating a lightning channel of ionised air molecules from the cloud to ground.

The main discharge, typically a series of discharges, now takes place through the lightning channel.

Negative lightning bolts are 1 to 2km (0.6 to 1.2 miles) long and have an average current of 20,000A.

Positive lightning bolts are much rarer and they can have currents of up to 300,000A.

Preventing damage when sailing in lightning

A lightning protection system (LPS) is designed to divert lightning energy to ground (in this case the sea), in such a way that no damage occurs to the boat or to people.

Ideally, this also includes protecting a boat’s electrical and electronic systems, but marine electronics are sensitive and this level of protection is hard to achieve.

Lightning protection systems have two key components: First, a mechanism to provide a path with as little resistance as possible that conducts a lightning strike to the water.

This is established with a substantial conductor from an air-terminal to the water.

This part of the LPS is sometimes called external lightning protection.

Second, a mechanism to prevent the development of high voltages on, and voltage differences between, conductive objects on the boat.

This is achieved by connecting all major metal objects on and below deck to the water by an equipotential bonding system.

Without this bonding system high enough voltage differences can arise on a boat to develop dangerous side flashes.

The bonding system can be thought of as internal lightning protection.

Rolling ball concept

Lightning standards, which apply ashore and afloat, define five lightning protection ‘classes’, ranging from Class V (no protection) to Class I.

There are two core parameters: the maximum current the system must be able to withstand, which determines the sizing of various components in the system, and the arrangement and number of the air terminals, aka lightning rods.

Let’s look at the arrangement of the air terminals first. It is best explained by the rolling ball concept.

A lightning strike is initiated by the stepped leaders and attachment sparks connecting to form the lightning channel.

The distance between the stepped leader and the attachment sparks is known as the breakdown distance or striking distance.

If we imagine a ball with a radius equal to the striking distance, and we roll this ball around an object to be protected, the upper points of contact define the possible lightning impact points that need to be protected by air terminals.

Lightning protection theories and classifications rely on a ‘rolling ball’ concept to define requirements, areas of risk and protected areas. Credit: Maxine Heath

The air terminal will theoretically provide a zone of protection from the point at which the terminal connects with the circumference of the rolling ball down to the point at which that circumference touches the water.

The shorter the striking distance, the less the radius of the rolling ball and the smaller the area within the protection zone defined by the circumference of the rolling ball.

The smaller the protection zone, the more air terminals we need. So, we use the shortest striking distance to determine the minimum number and location of air terminals.

Class I protection assumes a rolling ball radius of 20m; Class II assumes a rolling ball radius of 30m.

How batteries can explode – and how to avoid it

Marine electrical expert Nigel Calder explains why boat batteries emit hydrogen and how to minimise the dangers

Boat building standards are based on a striking distance/rolling ball radius of 30m (Class II).

For masts up to 30m above the waterline, the circumference of the ball from the point at which it contacts the top of the mast down to the water will define the zone of protection.

For masts higher than 30m above the waterline, the ball will contact the mast at 30m and this will define the limit of the zone of protection.

If Class I protection is wanted, the radius of the ball is reduced to 20m, which significantly reduces the zone of protection and, on many larger recreational boats, may theoretically necessitate more than one air terminal.

Protection classes

With most single-masted monohull yachts, an air terminal at the top of the mast is sufficient to protect the entire boat to Class I standards.

The circumference of the rolling ball from the tip of the mast down to the surface of the water does not intercept any part of the hull or rig.

However, someone standing on the fore or aft deck might have the upper part of their body contact the rolling ball, which tells us this is no place to be in a lightning storm.

Some boats have relatively high equipment or platforms over and behind the cockpit.

Protection classes to protect your boat while anchored or sailing in lightning

These fittings and structures may or may not be outside the circumference of the rolling ball.

Once again, this tells us to avoid contact with these structures during a lightning storm.

Ketch, yawl, and schooner rigged boats generally require air terminals on all masts, except when the mizzen is significantly shorter than the main mast.

The external LPS

The external LPS consists of the air terminal, a down conductor, and an earthing system – a lightning grounding terminal.

The down conductor is also known as a primary lightning protection conductor.

All components must be sized to carry the highest lightning peak current corresponding to the protection class chosen.

In particular, the material and cross-sectional area of the air terminal and down conductor must be such that the lightning current does not cause excessive heating.

The air terminal needs to extend a minimum of 150mm above the mast to which it is attached.

It can be a minimum 10mm diameter copper rod, or 13mm diameter aluminum solid rod.

It should have a rounded, rather than a pointed, top end.

VHF antennas are commonly destroyed in a lightning strike.

If an antenna is hit and is not protected by a lightning arrestor at its base, the lightning may enter the boat via the antenna’s coax cable.

A lightning arrestor is inserted in the line between the coax cable and the base of the antenna.

It has a substantial connection to the boat’s grounding system, which, on an aluminum mast, is created by its connection to the mast.

In normal circumstances, the lightning arrestor is nonconductive to ground.

When hit by very high voltages it shorts to ground, in theory causing a lightning strike to bypass the coax – although the effectiveness of such devices is a matter of some dispute.

Down conductors

A down conductor is the electrically conductive connection between an air terminal and the grounding terminal.

For many years, this conductor was required to have a resistance no more than that of a 16mm² copper conductor, but following further research, the down conductor is now required to have a resistance not greater than that of a 20mm² copper conductor.

For Class I protection, 25mm² is needed. This is to minimise heating effects.

Let’s say instead we use a copper conductor with a cross-sectional area of 16mm² and it is hit by a lightning strike with a peak current corresponding to Protection Class IV.

The conductor will experience a temperature increase of 56°C. A 16mm² conductor made of stainless steel (for example, rigging ) will reach well over 1,000°C and melt or evaporate.

Shrouds and stays on sailboats should be connected into a LPS only to prevent side flashes.

The cross-sectional area of the metal in aluminum masts on even small sailboats is such that it provides a low enough resistance path to be the down conductor.

Whether deck- or keel-mounted, the mast will require a low resistance path, equivalent to a 25mm² copper conductor, from the base of the mast to the grounding terminal.

Grounding terminal

Metal hulled boats can use the hull as the grounding terminal. All other boats need an adequate mass of underwater metal.

In salt water this needs a minimum area of 0.1m². In fresh water, European standards call for the grounding terminal to be up to 0.25m².

A grounding terminal must be submerged under all operating conditions.

An external lead or iron keel on monohull sailing boats can serve as a grounding terminal.

This owner of this Florida-based yacht decided to keep the keel out of the equation when is came to a grounding plate. High electrical currents don’t like sharp corners, so a grounding plate directly beneath the mast makes for an easier route to ground. Credit: Malcolm Morgan

In the absence of a keel , the cumulative surface area of various underwater components – propellers, metal thru-hulls, rudders – is often more than sufficient to meet the area requirements for a grounding terminal.

However, these can only be considered adequate if they are situated below the air terminal and down conductor and individually have the requisite surface area.

Metal through-hulls do not meet this requirement.

If underwater hardware, such as a keel, is adequate to be used as the grounding terminal, the interconnecting conductor is part of the primary down conductor system and needs to be sized accordingly at 25mm².

Propellers and radio ground plates

Regardless of its size, a propeller is not suitable as a grounding terminal for two reasons.

First, it is very difficult to make the necessary low-resistance electrical connection to the propeller shaft, and second, the primary conductor now runs horizontally through the boat.

The risk of side flashes within the boat, and through the hull to the water is increased.

Sailing in lightning: GRP hull, fairing filler and iron keel will have carried different voltages during the strike – hence this damage

An engine should never be included in the main (primary) conducting path to a grounding terminal.

On modern engines, sensitive electronic controls will be destroyed in a lightning strike, and on all engines, oil in bearings and between gears will create resistance and therefore considerable heat which is likely to result in internal damage.

However, as it is a large conductive object, the engine should be connected to the internal lightning protection system.

Internal lightning protection

On its way to ground, lightning causes considerable voltage differences in adjacent objects – up to hundreds of thousands of volts.

This applies to boats with a functioning external lightning protection system but without internal protection.

Although the lightning has been given a path to ground along which it will cause as little damage as possible, dangerous voltages can be generated elsewhere, resulting in arcing and side flashes, threatening the boat and crew, and destroying electronic equipment.

We prevent these damaging voltage differences from arising by connecting all substantial metal objects on the boat to a common grounding point.

The grounding terminal is also wired to the common grounding point.

By tying all these circuits and objects together we hold them at a common voltage, preventing the build-up of voltage differences between them.

All conductive surfaces that might be touched at the same time, such as a backstay and a steering wheel, need to be held to the same voltage.

If the voltages are the same, there will be no arcing and no side flashes.

The bonding conductors in this internal LPS need to be stranded copper with a minimum size of 16mm².

Note that there can be bonding of the same object for corrosion prevention, lightning protection, and sometimes DC grounding.

We do not need three separate conductors.

Electronic Device Protection

With lightning protection systems, we need to distinguish electric circuit and people protection from device protection.

Even with an internal LPS, high induced voltages may occur on ungrounded conductors (such as DC positive) which will destroy any attached electronics.

A mechanism is needed to short high transient voltages to ground.

This is done with surge protection devices (SPD), also known as transient voltage surge suppressors (TVSS) or lightning arrestors.

Marine-specific SPDs are few in number and domestic models are not suitable for boats

In normal circumstances these devices are non-conductive, but if a specified voltage – the clamping voltage – is exceeded they divert the spike to ground.

There are levels of protection defined in various standards depending on the voltages and currents that can be handled, the speed with which this occurs, and other factors.

This is a highly technical subject for which it is advisable to seek professional support.

Most SPDs are designed for AC circuits.

When it comes to DC circuits there are far fewer choices available to boat owners although there are an increasing number for solar installations that may be appropriate.

There is no such thing as a lightning-proof boat, only a lightning-protected boat, and for this there needs to be a properly installed LPS.

Even so, in a major strike the forces involved are so colossal that no practical measures can be guaranteed to protect sensitive electronic equipment.

For this, protection can be provided with specialised surge protection devices (SPDs).

The chances of a direct lightning strike on a yacht are very small, and the further we are north or south of the equator, the smaller this chance becomes.

It’s likely your chances of receiving a direct lightning strike are very much higher on a golf course than at sea.

‘Bottle brush’-type lightning dissipators are claimed by sellers to make a boat invisible to lightning by bleeding off static electrical charge as it builds up.

The theory rests upon the concept that charged electrons from the surface of the earth can be made to congregate on a metal point, where the physical constraints caused by the geometry of the point will result in electrons being pushed off into the surrounding atmosphere via a ‘lightning dissipator’ that has not just one point, but many points.

It is worth noting that the concept has met with a storm of derision from many leading academics who have argued that the magnitude of the charge that can be dissipated by such a device is insignificant compared to that of both a cloud and individual lightning strikes.

It seems that the viable choices for lightning protection remain the LPS detailed above, your boatbuilder’s chosen system (if any), or taking one’s chances with nothing and the (reasonable) confidence that it’s possible to sail many times round the world with no protection and suffer no direct strikes.

Whichever way you go, it pays to stay off the golf course!

A dramatic rescue operation unfolded off the coast of Australia on Tuesday after two sailors were stranded on a yacht overnight in extreme weather conditions.

The sailors, a 60-year-old man and a 48-year-old woman, were rescued in a multi-agency operation after their 19m yacht, the Spirit of Mateship, starting taking on water due to a mechanical issue.

The rescue operation was initiated at 1pm on Monday after the Spirit of Mateship sent out a distress beacon, and it took several hours for helicopters to locate the vessel. In the meantime, the yacht lost power and communication capabilities, and was battered by strong winds of up to 90kmph.

Ben Flight, duty manager at the Australian Maritime Safety Authority Response Centre, said a helicopter was able to establish radio contact with the yacht and fly above it but was unable to retrieve the passengers due to the challenging conditions.

A subsequent rescue attempt was also abandoned due to rough seas, leaving the sailors on board to endure a "horrible" night at sea, Mr Flight said.

“They were sort of just at the mercy of the elements. They would have been moving around uncomfortably. It would have been particularly windy, noisy, probably quite wet as well.

“I don’t imagine they would have got any rest overnight, so I imagine they’d be quite tired and very relieved to be rescued,” he was quoted as saying by CNN.

The NSW Water Police vessel Nemesis was able to make contact with the sailors at 1am on Tuesday, arriving at the scene at 3am.

However, extreme weather conditions prevented the crew from rescuing them.

Anthony Brazzill of the New South Wales  police described the conditions as "terrible”. The sailors had to jump onto a rescue boat one at a time, with Mr Brazzill praising the experienced mariners who executed the rescue.

"It’s a matter of just basically timing it,” he said. “Get the person to jump, as they’re coming in, get them to jump and catch, doing one at a time, obviously making sure that people have the life jackets on.”

The yacht had drifted 70 nautical miles overnight and the passengers were unable to bring the sails down, Mr Brazzill said.

“The yacht was running away from us as we were chasing it down the coast which obviously made it a challenge.”

The Australian Maritime Safety Authority said an emergency alert from the yacht was received on Monday, and a distress beacon was activated about 150km offshore from Nowra.

The sailors were rescued around 7.25am on Tuesday and were travelling to Sydney on board the Nemesis for medical assessment.

They were fatigued but uninjured and were expected to land at the NSW Police Marine Area Command late Tuesday night.

The Spirit of Mateship has taken part in several Sydney to Hobart races since 2013. The yacht was left in the ocean, with Mr Brazzill stating that their priority is to "save lives, not save boats”.

Coast Guard and Navy rescue mother, daughter stranded on sailboat outside of Hurricane Gilma

The woman, 47, and her child, 7, were on a 47-foot sailboat flying a french flag. also onboard were a cat, tortoise and a deceased man..

FILE: Coast Guard video shows flooding along Texas coast after Beryl

A video shared by the U.S. Coast Guard from a flight above the Texas coastline after Hurricane Beryl shows significant damage and flooding near Sargent.

HONOLULU – Rough seas beset a sailboat carrying a woman, her child and a deceased man about 1,000 miles east of Hawaii on Aug. 24. They were rescued by the U.S. Coast Guard and Navy , who hurried to reach the family ahead of Hurricane Gilma.

The Joint Rescue Coordination Center Honolulu watchstanders received a distress signal from the family at 12:33 p.m. on Saturday. The USCG said the JRCC inquired about vessels near the location of the distress signal.

Rescue aircraft were dispatched and, when they arrived on-scene, they saw the 47-year-old woman and her 7-year-old child on a 47-foot sailboat flying a French flag. The woman sent a mayday call saying that a deceased man was onboard.

Coast Guard rescues 2 people, 1 dog near St. Catherine’s Sound, GA

The Coast Guard rescued two people and a dog, Monday, after their vessel began taking on water near St. Catherine’s Sound, Georgia. 

The boat appeared to be drifting and taking waves over the beam, according to USCG officials. The weather conditions included 6-foot seas and 20 mph winds .

The following morning at 9 a.m., another aircraft crew reached the family, but were unable to establish direct communications.

At 5:20 p.m., a Singapore-flagged, 754-foot liquid petroleum gas tanker arrived after making an 18-hour trip to the sailboat. However, deteriorating weather conditions due to approaching Gilma prevented them from rescuing the woman and child.
