Navigation Lights for Sailboats (And How To Read Them)

Last Updated by

Capt Chris German

June 15, 2022

Navigation lights on a sailboat can be confusing. If you understand the reason behind why they are the way they are however, they can make a lot more sense.

At their heart, sailboats are really just a power boat and as such must adhere to all power boat rules such as navigation lights. Other times however, a sailboat is classified in a special category. They have a set of additional lights they CAN show as an option, but are not always required to do so.

That’s about as clear as mud if you ask me and I contend that that is where the confusion about lighting a sailboat begins.

Just because you can show a light to identify yourself in times of low visibility, does not mean you have to and then we add in a little sibling rivalry between power and sail and things get downright adversarial when it comes to navigation and the night.

Table of contents

The USCG says You’re a Power Boat Whether You Like It or Not

Much to the consternation of many a sailor who has earned a commercial license to drive their sailboat, when you received your credential from the USCG it says you are a master of steam and power across the top with no mention of wind as a source of propulsion.

It is not until you read the back pages of your little red book that feels like a passport and looks like a US Sailing credential, that you will see the term “sail auxiliary”. That is because most of the time the U.S. Coast Guard knows that you are primarily reliant on your mechanical power to propel your vessel.

It's a sad thing, but the days of commercially viable sail boats are done and all but the most select few even have sails let alone use them as their primary power source. All sail boats by law are powerboats, but not all powerboats are sailboats.

Navigation Lights for a Power Boat

As a power boat, you are required to show certain lights and have been required to do so before power was even invented. 

In the days of man powered vessels like the viking ships who relied on oars while in close quarters to power their vessels, they needed to show other boats, friend or foe, where they were by showing lanterns in the dark to identify themselves. As you know, it is a time honored rule among all the nations of the world both past and present, that you must avoid a collision at all costs while at sea and even the viking knew that you should not run into things.

By lighting the front and back of your boat, you could warn other boats of your presence as well as identify which way you were heading. As such there is a very specific rule in the Code of Federal Regulations Number 46 (CFR46 by common name) that spells out with detail how many, the color, the luminosity or brightness, the angle of visibility and the location of all of the lights required for navigation on every single boat, seaplane, submarine and other nondescript vessel conceived by man to date that they must show while underway in reduced visibility.

And there is no flexibility in the rules.

As such a power boat, and by extension all sailboats, MUST, without question show one green light on the starboard bow and one red light on the port bow and one all around white light or lights while operating in reduced visibility. These lights should shine at all 360 degrees of visibility with the bow lights shining at an angle of dead ahead to 22.5 degrees abaft the beam and the stern lights shining 225 degrees dead aft. A forward facing masthead light that is white in color shall shine forward to comply with the directive that all vessels must carry an all around white light. For more read here .

As you can see, there isn’t much wiggle room when it comes to lights that must be shown.

Sailboats get a little flexibility with lights

Sailboats however, are a little different when they are in fact sailboats, which is only when you are entirely reliant on the wind for power and in no way reliant on any mechanical or manual means of propulsion. And for good reason.

Back in the day when men were men and sailboats were wooden, fire was a major concern. Sails were coated with wax and other flammable substances and the wood on boats was saturated with oils and grease. Even the ropes were plant materials saturated with oils to keep them pliable and strong.

Add those highly flammable substances to a parching environment like the sea and you had what was essentially a giant floating tinderbox.

Then tell that giant floating tinderbox that they need to identify themselves to the world at large at night using oil lamps with flames because batteries and lights were not invented yet. It didn't take very long or very many ships burning to the water line for the Governments to say to the sailboats, you get to do things a little different.

As such, sailboats are given special dispensation when it comes to lights aloft. They don't have to show an all around white light in their rigging because no one wanted to set their rig on fire with oil lamps 60 feet up in their rig.

However, when a sailboat takes their sails down such as when they are powered or at anchor, they must resume the display of an all around white light or lights aloft. That became a real challenge with aluminum masts and the disappearance of rat lines on the shrouds because there was no easy way to climb the rig and check the bulbs up the mast on a regular basis. 

Red over Green Sailing Machine

I have no idea where the history of this particular light comes from, but if you ever take a deck exam with the USCG, you better remember this mnemonic. An all around red light over an all around green may be displayed on a vessel during times of reduced visibility to indicate that a vessel is operating under sail power alone. 

I won’t even speculate on how or why they came up with this particular light configuration, but if you want to use these lights as a sailing vessel, you can do so, but that means that you will need three all round lights at the top of your mast, an all around white, an all around red and an all around green, just in that order.

The red over green is to be displayed in addition to the running lights or the red and green bow lights with the 225 degree stern light. As always, when the motor comes on, so does the steaming light or the forward facing white light that is also usually about ¾ of the way up on your mast to complete the requirement of an all around white light that indicates a power vessel.

What is a “steaming light” and why are you mentioning it now?

Most sailboat electrical panels will have a switch that is labelled “steaming light” and it will only come on when your anchor light is off. This is probably the most confusing part of sailboat navigation lights so if you are confused about this, you're in good company as most people are. 

A “steaming” light is named thusly, going back to the days of steam powered sailboats where when they fired up their boilers and doused the sails, they became a power boat once again. There aren’t too many steam powered boats, let alone steam powered sailboats, but the name stuck and it is a vestige of a bygone era.

Either way, when you fire up your motor, you turn on your “steaming light” and that locks out the all around white light which is used for anchoring to minimize the number of switches on your panel and reduce the number of wires in your mast. The fewer wires, the less chance of something not working or becoming disconnected.

The steaming light and the anchor light both go up the mast, but you can’t use an all around white light while using the 225 degree stern light at the deck level because to other boaters you would look like you have two white lights from the stern and that would be confusing.

The anchor light is used exclusively for anchoring while the steaming light is used to indicate you are a power vessel while underway.

As to why I am mentioning it now in the article, is because this would have blown your mind if I started with this subject cause it can be really confusing stuff.

Aspect Recognition with Lights

Remember when I said earlier that lights can help you tell others which way you are heading as well as tell you which way other boats are heading? That is called the aspect of the vessel and the USCG tests you on this for your deck exam as well. 

Knowing that the bow lights go 22.5 degrees abaft the beam on both sides or 112.5 degrees on each side, and the stern light faces 225 degrees aft for a total of 360 degrees of visibility, you can tell a lot about where a boat is heading and who has the right of way.

One thing that's easy to remember is red means stop and if you see a vessel's red light, it means stop as you are the give way vessel and approaching the other vessel from his port side. Conversely it works with green as well as that means you are approaching from the other vessel's starboard side and you are the standon vessel.

If you see a red and green light equally low on the horizon, that means your heading dead on into another vessel's path and conversely if all you see is a white light low on the horizon, it means you are overtaking another vessel power or sail, we don’t care because it is an overtaking situation. However, any time you do see a white light aloft in addition to the red and green bow lights, you know you are encountering a power boat.

Then there are angular approaches as well, where you see white and red or white and green light low on the horizon. You know in that case you are seeing a portion of the bow lights and stern lights from the side approaches of a vessel. Based on which direction those lights are heading, you can deduce which way that boat is going in relation to your boat.

So put it all together and you see a green light and a white light low on the horizon with a red over green light aloft, you know that you are approaching a sailboat that is traveling to your port and that might make you the standon vessel. That is of course, if we didn’t concern ourselves with windward and leeward and port tacks and starboard tacks, but that is a discussion for another article. So stay tuned when we talk about sailing rules and the right of way. But for now, do good, have fun and sail far.

Steaming Light on Sailboat: A Guide to Proper Usage

by Emma Sullivan | Aug 11, 2023 | Sailboat Maintenance

== Short answer: Steaming light on sailboat == A steaming light is a white navigation light fitted on the mast of a sailboat to provide visibility during low-visibility conditions. It is typically placed near the front side of the mast and angled downwards to indicate that the vessel is under power and moving forward. This light helps other boats identify and avoid collisions, ensuring safe navigation at night or in limited visibility situations.

Understanding the Purpose of a Steaming Light on a Sailboat: What You Need to Know

Have you ever been out on a sailboat and noticed a small light at the top of the mast? You might have wondered what its purpose is or why it’s necessary. Well, that little light is called a steaming light, and it plays a crucial role in ensuring safety and navigation on a sailboat . In this blog post, we will dive into the details of understanding the purpose of a steaming light on a sailboat.

To begin with, let’s clarify what exactly a steaming light is. A steaming light is a white-colored navigation light located on the front of the mast or near the bow of a sailboat. Its main function is to provide visibility to other vessels during low-light conditions or at night. This means that whether you’re sailing in foggy weather, dim lighting, or after sunset when natural visibility decreases, the steaming light will maximize your boat’s presence to prevent collisions with other boats.

So why is it specifically called a “steaming” light? The term “steaming” refers to sailing when using an engine rather than relying solely on wind power. When you are using your boat’s engine for propulsion instead of sailing with just your sails, it is known as “motoring” or “steaming.” The steaming light got its name because it primarily signifies that the vessel has powered propulsion engaged rather than utilizing only wind power.

Now that we know what a steaming light does and where it gets its name from let’s discuss more about its importance. One major reason for having this navigation aid onboard is compliance with international boating regulations and standards set by organizations like COLREGs (Convention on the International Regulations for Preventing Collisions at Sea). These regulations ensure safe navigation practices globally and require boats to display certain lights for visibility purposes both to avoid accidents and allow other captains to understand their intentions.

When operating under engine power, displaying only proper red (port) and green (starboard) sidelights can confuse other boaters, as these lights typically indicate the presence of a vessel under sail. To avoid such confusion, the use of a steaming light in conjunction with the appropriate sidelights clarifies that the boat is motoring and not just relying on its sails for propulsion.

Another important aspect to note about steaming lights is their distinct positioning on a sailboat . Typically, they are mounted at least one meter above the deck level to ensure maximum visibility. This height allows for unobstructed illumination, making it easier for other boaters to see your vessel from afar. It’s crucial to maintain this specific positioning to comply with regulations and maximize safety on the water.

In summary, understanding the purpose of a steaming light on a sailboat is essential for any sailor or boat owner. Its primary function is to provide visibility during low-light conditions or at night when using engine power instead of relying solely on wind power. By complying with international regulations and properly displaying navigation lights like a steaming light , you enhance safety by avoiding confusion between sailing and motoring vessels. So next time you’re out on the water after dusk or in foggy weather, remember the importance of that little but mighty steaming light atop your sailboat’s mast!

Step-by-Step Guide: How to Install a Steaming Light on Your Sailboat

Installing a steaming light on your sailboat might seem like a daunting task, but with the right guidance and a bit of patience, you’ll have it up and running in no time. In this step-by-step guide, we’ll walk you through the process of installing a steaming light on your sailboat, ensuring that you have a safe and well-lit vessel on your next sailing adventure.

Step 1: Gather the necessary tools and materials Before diving into the installation process, make sure you have all the tools and materials required. You’ll need a steaming light fixture, wires (preferably marine-grade), heat shrink tubing, electrical connectors, wire cutters/strippers, crimping tool, electrical tape, screwdrivers (flathead and Phillips-head), mounting brackets or screws if needed, and a drill with appropriate bits.

Step 2: Identify the ideal location for installation Finding the right spot for your steaming light is crucial as it needs to be clearly visible from all angles while ensuring it won’t interfere with other equipment or rigging. Typically, sailors prefer placing it at the masthead or near where the mast meets the deck.

Step 3: Prepare for installation Ensure that all power sources are disconnected before beginning any work. Next, carefully remove any existing fixtures or wiring from the chosen location (if applicable). If there’s already an ample power supply nearby (e.g., an existing navigation light circuit), tap into it to minimize additional wire routing.

Step 4: Mount the steaming light fixture If your chosen spot requires mounting brackets or screws for support, position them accordingly using suitable hardware. Ensure they are firmly secured to prevent any movement due to vibrations caused by sailing conditions. Attach the steaming light fixture securely to these brackets using screws provided with the fixture.

Step 5: Connect wires and ensure proper wiring configuration Strip off some insulation from both ends of each wire to be connected. Using heat shrink tubing, slide it over one end of each wire to ensure a clean finish once the connections are made. Connect the appropriate wires from the steaming light fixture to the power supply or existing wiring and secure them using electrical connectors. It’s crucial to follow a proper wiring configuration, so refer to the manufacturer’s instructions or consult a professional if needed.

Step 6: Test functionality and safety Once all connections are securely made, reconnect the power source and turn on your sailboat’s battery. Switch on your steaming light and verify that it’s functioning correctly. Check for any loose connections, flickering lights, or signs of overheating during this testing phase. If everything looks good, proceed to finalize the installation.

Step 7: Secure and protect the wires Using zip ties or cable clamps, neatly bundle and secure all wires along their path towards the power source or existing wiring nearby. This step is especially important as it prevents any accidental snagging or damage caused by movement while sailing.

Step 8: Add finishing touches To ensure long-lasting durability and protection against environmental factors (moisture, saltwater), add an extra layer of weather-resistant insulation tape around exposed wiring connections. This additional safeguard will help shield your newly installed steaming light from any potential issues that may arise due to harsh maritime conditions.

By following these step-by-step instructions carefully, you can install a steaming light on your sailboat like a pro! Not only will you be adding an essential safety feature to illuminate your vessel in low visibility situations but also enhancing its overall aesthetics for impressive nighttime sailing adventures. So don’t let darkness dampen your enthusiasm – take charge of your boat’s illumination and enjoy safe sailing every time!

Choosing the Right Steaming Light for Your Sailboat: Factors to Consider

Picture this: you’re sailing gracefully through the open waters, harnessing the power of the wind, when suddenly darkness descends upon you. The sun has set, and it’s time to rely on your trusty steaming light to guide your way. But wait! How do you choose the right one? Fear not, fellow sailors, for we are here to shed some light (pun intended) on this important decision. Here are some factors you should consider before picking out the perfect steaming light.

1. Regulations and Safety Standards: First and foremost, always adhere to regulations and safety standards set by maritime authorities. Different jurisdictions might have specific requirements regarding visibility range, color specifications, mounting heights, and more. Familiarize yourself with these guidelines to avoid unnecessary fines or safety hazards.

2. Visibility: Ahoy there! One of the primary purposes of a steaming light is to ensure that other vessels can see you while underway. Consider both the intensity of the light and its range. Opt for a light that boasts exceptional brightness without blinding nearby captains (we don’t want any sailors rubbing their eyes in confusion!).

3. Energy Efficiency: As responsible stewards of our oceans, sustainability should always be on our minds – even when it comes to choosing a simple steaming light. Look for LED lights as they consume significantly less power compared to traditional incandescent bulbs while providing excellent illumination throughout your journey.

4. Durability: When it comes to marine equipment, durability is essential since it may face harsh weather conditions such as intense sun exposure and heavy rainstorms – not to mention saltwater corrosion! Seek a steaming light specifically designed for marine environments; preferably made from strong materials like stainless steel or robust plastics.

5. Ease of Installation: Unless you’re an adept sailor who thrives on complex wiring tasks reminiscent of navigating through treacherous waters, selecting a steaming light that is easy to install and maintain is paramount. Look for lights that come with simple mounting options and clear instructions – nobody wants to be left in the dark (literally) while fumbling around with confusing installation manuals.

8. Value for Money: As much as we hate to admit it, costs play an important role in decision-making processes. Research different brands and models to find out which ones offer excellent value for money without compromising on quality or reliability. Remember, skimping on safety equipment isn’t just unwise; it could also turn into an expensive mistake down the line.

By considering these factors and conducting thorough research, you can confidently choose the right steaming light for your sailboat – ensuring safer navigation during both day and night expeditions. May your voyages always be illuminated by the perfect beacon, guiding you towards memorable adventures on the high seas !

Troubleshooting Tips for Maintaining your Steaming Light on a Sailboat

Maintaining the steaming light on a sailboat is essential for safe navigation, especially during low visibility conditions. This small but mighty light not only helps you see ahead but also signals your presence to other vessels on the water. However, as with any electrical equipment, issues can arise that require troubleshooting and maintenance. In this blog post, we will provide you with professional, witty, and clever tips to ensure your steaming light stays in top-notch condition.

1. Check the Basics: First things first – let’s start with the basics! Before diving into complex troubleshooting techniques, make sure to inspect the obvious factors that could lead to a malfunctioning steaming light. Check if it’s properly connected and securely fastened to avoid loose or faulty wiring connections—an easy fix that might save you hours of troubleshooting later!

2. Don’t Underestimate Corrosion: Ahoy there Captain! When it comes to maritime environments, corrosion is your worst enemy. The combination of saltwater spray and constant exposure can wreak havoc on electrical systems onboard; your steaming light is no exception! Regularly inspect the contacts and terminals for signs of corrosion or rust buildup. Use a brush or a fine-grit sandpaper to remove any unwanted visitors from these surfaces. Remember, a clean connection ensures optimal performance !

3. Fuse in Time Saves Nine: Some sailors tend to forget about fuses while troubleshooting their boat’s lighting system—don’t be one of them! The humble fuse protects your electrical system from potential overloads, shorts, and fire hazards caused by an unexpected surge in current flow . If your steaming light fails to illuminate even after checking wiring connections and corrosion issues, don’t overlook this vital component! Replace any blown fuses promptly according to their specifications.

4. Shine Bright Like a Pro: “A dim steaming light? Oh buoy!” Dim lights can affect visibility for both yourself and other mariners around you—so don’t compromise on this important safety feature! If your steaming light seems less luminous than usual, check for bulb degradation. Even a slightly loose bulb can significantly reduce its brightness. Tighten it up carefully or, better yet, replace it with a fresh and bright LED bulb that offers increased energy efficiency and longevity.

5. Put the Voltmeter to Work: When all else fails, put your trust in technology! The trusty voltmeter can help you diagnose electrical issues like a true sailor troubleshooter. Connect the meter to the terminals of your steaming light and measure the voltage supply when turned on. An insufficient voltage reading indicates wiring problems or potential battery drain issues that need further inspection.

6. Beware of Murphy’s Law: Ahoy there Landlubber! When troubleshooting any onboard issue, always keep Murphy’s Law in mind: “Anything that can go wrong will go wrong.” That’s why having spare parts like bulbs, fuses, and even extra wire connectors is essential for sailboat maintenance. Preparation is key when cruising on the open water !

7. Seek Help from Fellow Sea Dogs: Remember, you’re not sailing alone in this boat—a vast community of seasoned sea dogs is out there ready to lend a helping hand! Don’t hesitate to consult online forums or reach out to fellow sailors who might have encountered similar issues before. They may share their witty anecdotes and clever solutions that could solve your steaming light troubles faster than you think!

At the end of the day, maintaining your steaming light is not just about complying with maritime regulations; it’s about ensuring safe passage for both yourself and others on the waterways. By following these troubleshooting tips – from checking connections and addressing corrosion to involving technology like voltmeters – you’ll be able to maintain an illuminated path amidst challenging maritime conditions.

So set sail confidently knowing that even if darkness falls upon you (figuratively or literally), you’ll be well-prepared to troubleshoot and maintain your steaming light like a true professional sailor.

Don’t Set Sail Without It: The Importance of a Functional Steaming Light

When embarking on a sailing adventure, it’s crucial to ensure that every aspect of your vessel is in impeccable condition. From the sails to the rudder and everything in between, one essential component that often goes unnoticed is the steaming light. This small yet mighty fixture plays a significant role in ensuring both your safety and that of other sailors out on the water. In this blog post, we will explore why having a functional steaming light should never be overlooked when setting sail.

Firstly, let’s understand what a steaming light actually is. Mounted on top of the mast or at its front, the steaming light serves as an all-around white navigation light for boats under power. Its primary purpose is to help you stay visible to other vessels nearby by indicating your direction of travel at night or during periods of diminished visibility such as fog or heavy rain.

Now, you may be wondering why this seemingly inconspicuous light deserves so much attention. Well, think about it – imagine sailing through dense fog without a working steaming light! Without this beacon guiding your path, not only are you jeopardizing your own safety but also putting fellow seafarers at risk by refusing to comply with maritime regulations.

Additionally, navigating harbors and congested waterways becomes an even greater challenge without an operational steaming light. Picture yourself approaching a bustling marina late into the evening; by illuminating your boat’s foredeck with its bright white glow, the steaming light acts as a signal for others around you to be cautious and respect your right of way. This simple yet effective communication tool prevents accidental collisions and fosters harmony among boaters sharing busy waters.

But if safety isn’t reason enough to prioritize a fully functioning steaming light before each voyage, consider this: Mariners have an inherent responsibility to adhere to international maritime regulations set forth by bodies such as the International Maritime Organization (IMO). These regulations explicitly state that every vessel under power must display a white steaming light while underway during hours of darkness or limited visibility. By neglecting this requirement, you not only risk severe penalties but also jeopardize your reputation as a responsible boater.

Now that we understand the importance of a functional steaming light, it’s essential to keep it well-maintained and regularly inspected. After all, there’s nothing worse than setting sail only to have your navigation light fail at the most inopportune moment. Inspecting the wiring, replacing any worn-out bulbs, and ensuring proper alignment are simple steps that should form part of your pre-departure routine.

Remember, when it comes to sailing, “Don’t Set Sail Without It: The Importance of a Functional Steaming Light.” This unassuming yet crucial piece of equipment acts as both an indispensable safety feature and a responsible adherence to maritime regulations. So, before you embark on your next voyage, take the time to ensure that your steaming light is functioning optimally – after all, smooth seas start with being visible and considerate towards fellow sailors!

Navigation Lights

• You are required to display the appropriate lights at night or during times of reduced visibility.

Navigation lights are used to prevent collisions at night or in times of reduced visibility, and are an essential tool in keeping you and your vessel safe. Nav lights allow you to see other nearby vessels, and allow other vessels to see you.

Nav lights also provide information about the size, activity, and direction of travel. By understanding the characteristics of Nav lights, you can determine an appropriate course of action as you approach another vessel.

On any vessel, navigation lights have a specific color, (white, red, green, yellow, blue), arc of illumination, range of visibility, and location, as required by law and regulations. For the purposes of this course, we will concentrate on pleasure boats under 65 feet in length. Knowledge of navigation lights is important to a small-boat skipper for separate, but important, reasons.

• You are legally responsible for displaying lights of the proper color, intensity, location and visibility on your boat.
• Knowing the type and heading of another boat.

Legal Requirements

Vessels are required to show the proper navigation lights from sunset to sunrise in all weather conditions, good and bad. During these times, no other lights that could be mistaken for lights specified in the Rules of the Road can be displayed, nor any lights that impair the visibility or distinctive character of navigation lights, or interfere with the keeping of a proper lookout. The Rules also state that navigation lights must be shown in conditions of reduced visibility, and may be shown at other times considered necessary.

It's Your Responsibility

It is the responsibility of the owner/operator of a vessel that she show the proper navigation lights for her size and the waters in which she is operating. It is not the responsibility of the manufacturer, importer, or selling dealer. Many boats are delivered with lights that do not meet legal requirements with respect to technical characteristics or placement on the vessel. Remember also, that the angles of visibility must be met when the boat is underway-if your boat rides at a significant bow-up angle, take that into consideration when installing and/or checking your lights.

Navigation Lights for Powerboats

Power driven vessels underway shall exhibit a masthead light forward, sidelights and a stern light. Vessels less than 12 meters in length may exhibit an all around white light and side lights. Power driven boats on the Great Lakes may carry an all around white light in stead of a second masthead light and stern light combination.

Sidelights - Colored lights - red on port and green on starboard - showing an unbroken arc of the horizon of 112.5 degrees, from dead ahead to 22.5 degrees abaft the beam on each side.

Combination lights - Sidelights may be combined in a single fixture carried at the centerline of the vessel.

Stern light - A white light showing over an unbroken arc of the horizon of 135 degrees, centered on dead astern.

Navigation Lights for Sailing

A sailing vessel of less than 7 meters in length shall, if practicable, exhibit regular navigation lights, but if not practical, she shall have ready at hand an electric torch or lantern showing a white light which shall be exhibited in sufficient time to prevent collision.

Diving Lights

Another light display that you may see in resort areas, or waters that have wrecks or reefs, is the night diving configuration. This has three vertical masthead lights, that have a red-white-red sequence. You must maintain a good distance from these vessels, and you should also be aware that there may be divers near you.

Interpreting what you see

It's great that you're learning the basics of lights - what is required and when they're required. But, this in only the beginning. You must also learn how to interpret the navigation lights that you see when you are underway at night- and for your safety-learn it well.

For instance, if you see a vessel approaching that shows a light pattern such as the ones to the right, you immediately know that you are in a crossing situation, and that you must yield to the other vessel - that's why it is red.

Seeing a green light over a white light indicates a fishing vessel actively trawling. You not only need to avoid the vessel, but you also need to remember that it could potentially have a very large net deployed that you will also need to avoid.

And there are numerous other lights and combinations of lights that you must be able to instantly recognize - the lights for a sailboat that is privileged over a motorboat, the special lights of various fishing vessels, a dredge or a vessel not under command. Study the requirements for navigation from the viewpoint of a "looker" as well as a boat owner.

Boat Navigation Lights Rules: Illustrated Beginners Guide

When navigating at night, the lights on other boats are your first clue about the moving dangers around you. And your navigation lights are your first line of safety in avoiding collisions in the dark, and they tell others vessels what you are and what you are doing. The rules sound complex, but with a little understanding you can get the basics for any situation.

So what are the basic navigation light rules? For most small vessels, motoring requires red and green (port and starboard) lights, and a white light visible in all directions around the boat. This is almost always a stern light and a masthead light on sailboats. Boats under sail require port and starboard lights, and a white stern light. Sailboats below sixty-five feet may show a tricolor light at the masthead instead of side and stern lights when sailing.

That's it, in a nutshell. There's a little more to it, as the rules change with different sizes and there are some specifics about angles of display for the colors. Identifying other ships at sea requires more study, but the basics are the same. And it's not much trouble to make sure you've always got the proper lights on your vessel.

On this page:

What are the official colregs rules for your sailboat, what about the uscg (united states coast guard) rules, lighting at anchor, identifying the boats around you.

The International Regulations for the Prevention of Collision at Sea , abbreviated "COLREGS" is very specific about the lights required, their shapes and sizes, and the distance they must be visible. For the smaller boat, the following definitions apply.

• Masthead Light - a white light placed centerline on the boat showing an arc of 225 degrees with 112.5 degrees either side of the front of the vessel.
• Sidelights - A red light on the port side and a green light on the starboard. They must show an arc of 112.5 degrees from centerline of the bow.
• Stern light - A white light on the stern of the boat showing an unbroken arc of 135 degrees from centerline of the vessel.
• All-round light - A light showing in an unbroken arc of 360 degrees.

The good news is you need not measure these angles. Any properly installed USCG or COLREGS approved light which will cover the correct arcs. If you have to replace the original light from your boat, make sure it's with an approved replacement.

Lights When Sailing

The specific rules for a sailboat under sail are in COLREGS Rule 25 and vary slightly with the size of the boat. A sailboat powering is considered a power boat and falls under in Rule 23.

• Under 23 feet (7 meters) - side lights and a stern light, possible. If these lights can not be displayed a light must be kept at hand to help avoid a collision. This can be a bright flashlight.
• Over 23 feet - Side lights visible to one nautical mile and stern light visible for two.
• Vessels under 65 feet may combine both sidelights into a single lantern on the bow.
• May show a tricolor light on the masthead instead of sidelights and a stern light. It's one or the other though, do not show these lights at the same time .
• Masthead light must be visible for three nautical miles, all other lights must have a two nautical mile visibility.
• Side lights must be separated.
• May not show a masthead tricolor light.
• Masthead light must have five nautical mile visibility, all other lights must be visible for two nautical miles.
• Optional masthead lights - any vessel under sail may display a red light over a green light at the masthead with sidelights and stern light. The red over green may NOT be displayed with a masthead tricolor light. It's one set or the other.

Lights When Motoring

For all navigational purposes a sailboat under power is considered a power boat. This includes motor sailing - if the engine is on and providing propulsion you are on a power boat, even if the sails are up . This applies to navigation lighting, sound signals in fog and limited visibility, and rights of way.

Sailboats under 50 meters under power need to show:

• A masthead light
• Stern light

A power-driven vessel under 23 feet (7 meters) that does not exceed seven knots of speed may display an all around white light, though sidelights should be used if available.

The USCG has published its own "Rules of the Road" that are based on the COLREGS. In addition, it has rules for the "Inland Waterways" for rivers, inland lakes and the Great Lakes.

The good news is this has no impact on what you have to do with your own boat.

They mostly relate to lighting changes on towed vessels like barges and tugs. For example, a vessel towing or pushing another vessel in the ocean under COLREGS shows two masthead lights, sidelights and a stern light, whereas in Inland Waterways the towing or pushing vessel displays two yellow towing lights instead of a white stern light.

If you sail on lakes, rivers or the Great Lakes where towed commercial traffic is common you should learn the inland lights, but coastal or ocean sailors will never see these.

When you anchor outside a designated mooring field, you should display an all around white light at the masthead or as high in the boat as practical.

If your boat is large and has a very tall mast, you may wish to display another light closer to the waterline. Boats approaching in the dark may not see a light on a mast sixty or seventy feet in the air when they are close to your boat.

We use a simple garden path light on our stern when we anchor, left in a rod holder or flag socket. It comes on automatically at dusk and is a cheap and easy way to be more visible. There is no specific rule stating you can not display more lights than required, or the nature of any lights beyond the required all around light.

The COLREGS also specify that a round black "daymark" should be displayed in the rigging of any vessel at anchor. Very few small vessels observe this, however it is the correct display for a vessel in an anchorage.

If you tie to a mooring in a marked mooring area you are not required to display anchor lights, but there is no harm in doing so.

The other important reason to know your lights is to figure out what's going on around you at night. The water may be ablaze with white, red, green and other lights at night and they are your first key to avoiding collisions and problems.

All combinations of lights for fishing boats, commercial vessels, and so on are outside this post‘s scope. The odds are small you will encounter a submarine, seaplane or hovercraft at night, but there are regulations regarding specific lighting for each of those vessels!

There are a few fundamentals to help you figure out what that is you see on the horizon, which way it is going, and whether it is a danger to you.

Port Wine is Red

The fundamental rule is that red sidelights will ALWAYS be on the port side of a vessel, and green lights will always be on starboard. However, some vessels can use all around red and green lights for other purposes, though those will be higher than sidelights.

The light‘s on a ship is not important, some large tankers and freighters will have their sidelights far aft and put them on the superstructure for better visibility. It is not safe to assume that sidelights you can see are on the bow of large vessels .

When you can see the color, you know which way the bow is pointing. If it's red, it's pointing more or less to the left and will travel in that direction. A green light shows it is heading more or less to your right.

If you can see the red and green lights at the same time, you are looking directly at the bow of the vessel. When you are far away, this isn‘t as alarming as if you are close crossing. Seeing red and green lights together on a vessel is something you never want to see for long.

Be aware of red and green lights used in combination with other red, green and white lights. These may not be running lights and could have other significance.

Tankers, Freighters and Large Ships

Tankers, freighters and large ships will have side lights, a stern light and a masthead light. In addition, on vessels over 50 meters there will be a second masthead light further aft and higher than the forward light. The masthead light positions are a better tipoff to the bow direction and how far from the bow the sidelights might be. Remember - on a large vessel the sidelights may not be at the bow or even close to it.

USCG Inland Rules allow for a second all-around white light on large vessels on the Great Lakes instead of a second masthead light.

Fishing Boats

Fishing boats engaged in fishing will have more complex light displays. When they aren't fishing, they will show lights like any power vessel, but Rule 26 spells out light combinations that vary by the fishing activity being done. In general:

• Boats which are Trawling but not making headway will display a green all-around light over a white all-around light , and a masthead light aft of these lights. Boats making headway while trawling will show these lights, plus sidelights and a stern light.
• A vessel fishing other than trawling will show a red all-around light over a white all-around light . When making way they will also show sidelights and a stern light.
• If a vessel has gear more than 150 meters away from the boat, it will show a second all around light in the direction of the gear. The best rule is to give fishing boats as wide a berth as you can at night. They're easy to pick out if you check the top light configurations but their course may be difficult to predict.

Towing and Pushing

Towed vessels can be the most dangerous to cross, but they have the most lights to tell you what is happening. Refer to COLREGS or the USCG Rules of the Road Rule 24 for all combinations You can pick a tow/push vessel out with the following lights:

• Two or three masthead lights in a vertical line. Three masthead lights shows a tow over 200 meters. Additional masthead lights may show for larger tow vessels.
• A towing light (yellow light with the same characteristics as a stern light) directly above the stern light.
• The will also have side lights and a stern light.
• The towed vessel will show sidelights and a stern light. Lighting may vary under USCG inland rules, where towing lights may replace stern lights. Learn these differences if this is your regular cruising ground. If you think there is a tow ahead of you, always go well behind the aft most set of lights. Never go between a tow and avoid crossing ahead if possible as it may restrict their maneuverability.

Special Situations

There are several rare situations you may encounter. As a general rule, if there are a lot of lights and you don't understand them look for the sidelights on a moving vessel. If you can find them and figure out the direction it is moving, it makes the vessel easier to avoid. Stay well clear of lights you do not understand if you can avoid them without risk.

Most of these signals are used by larger, commercial vessels and you will not need them.

They use these light combinations with other light combinations. For example a towing vessel may also be restricted in maneuverability, and a vessel constrained by draft will show running lights if moving.

• Not Under Command - two all around red lights in a single line
• Restricted in Ability to Maneuver - red, white then red in a single line
• Constrained by draft - three all around red lights

Navigation Lights on Sailing Yachts and Motor Boats

Navigation lights ensure the safety of everyone at sea. The Convention on the International Regulations for Preventing Collisions at Sea (IMO COLREG 72) precisely sets out the guidelines for navigation lights, i.e., displaying lights, their range (distance from which the light is visible), as well as how they should be constructed and assembled. Our guide is of interest to sailors and sports boats enthusiasts with boats up to 20 m in length.

Regulations and official certifications:

When must navigation lights be displayed, what are the regulations concerning the use of navigation lights at sea, how do i know that my lights are eu-compliant, what is a ce mark, how are navigation lights defined, minimum range of navigation lights:.

Navigation lights – Conventional and LED:

What distinguishes led from conventional navigation lights.

• Replacement bulbs for conventional & LED lights

What are the advantages of LED navigation lights?

Switching from conventional to led navigation lights.

According to COLREGs part C, rule 20), navigation lights must always be used on board from sunset to sunrise or during the day if visibility is poor.

Please refer to the German Traffic Regulations for Navigable Maritime Waterways , §8 -10 and Preventing Collisions at Sea. Part C - Lights and Shapes. rules 20 - 31, and annexes I 1. - 14 for the exact wording.

NOTE: Vessels that are authorised to fly the German flag are generally only permitted to use approved navigation lights and sound signalling devices.

EU approval can be identified via the wheel mark symbol and the notified body number. BSH approved navigation lights (previously DHI) are marked with a model number (e.g., BSH/00/01/90).

However, even older lights with DHI approval that have already been installed maintain their approval, despite the changes made by the BSH.

In addition to the wheel mark symbol and German BSH approval, some lights are also approved by other countries, such as RINA (Registro Italiano Navale), MCA (Maritime and Coastguard Agency) and the USCG (United States Coast Guard). These are now recognised, provided the approval comes from the national approval body recognised in the country of origin.

National bodies whose accreditation is currently recognised in Germany:

The wheel mark symbol indicates approval of the Marine Equipment Directive (MED). This approval is valid for all EU member states, both for commercial vessels and recreational shipping.

0098 = Notified Body number (here 0098 = Germanischer Lloyd in Hamburg) 18 = year in which the mark is affixed, here 2018

• A CE mark is a symbol that must be affixed to a product by the manufacturer before it is sold on the European market. It indicates that the manufacturer is aware of the specific requirements for the product in question and that it fulfils the requirements of relevant European product directives. A CE mark does not supersede approval according to collision prevention regulations.
• Navigation lights are defined in detail by the International Maritime Organization (IMO), according to the International Regulations for Preventing Collisions at Sea, 1972 (COLREGs) Convention on the International Regulations for Preventing Collisions at Sea, 1972), in sections C and D. The following rules apply:

Which navigation lights are required on board according to IMO COL REG?

Definitions according to the 1972 International Regulations for Prevention of Collisions at Sea (COL REG 72):

1. Side lights for starboard and port

A green light on the starboard side and a red light on the port side, which shine from dead ahead in an arc of 112.5° aft to a point 22.5° abaft the beam (behind the beam) on either side of the vessel. On ships of less than 20 metres in length, the two individual sidelights may be replaced by a dual-colour combined light. This must be centrally located on the bow and stern axis.

2. Stern light

A white light mounted as close to the stern as possible and shines dead ahead in an arc of 135° (67.5° to each side). The mounting height should be aligned to the height of the side lights and should never be higher.

3. Three-colour light for sailing vessels (sailing lights)

On sail boats up to a length of 20 m, the side light and stern light can be combined into one three-colour light mounted on top of the mast. However, as soon as the sail boat's motor is engaged, the use of a three-colour light is no longer permitted. The rules for motor-powered vessels then apply.

4. Mast-head light

A white light placed over the centre line of the vessel and shines dead ahead in an arc of 225° (from straight ahead up to 22.5° more aft than crosswise to each side). The mounting height should be at least 1 m higher than the side lights. In the past, the mast-head light was also referred to as a steam boat light or steamer light, as it is only seen on ships that operate under engine power.

5. Signal light or all-round light

A light that shines in a complete circle of 360°. It may emit white, red or green light, depending on use. Examples of use: All sailboats and motorboats at anchor must exhibit a white anchor light . Ships over 12m in length must, if necessary, display vessel-in-distress lights (two red signal lights) placed at a vertical distance of at least 12 m. The distance between such lights must not exceed 1 m.

From what distance must navigation lights be visible?

The range indicates the distance from which the light can be seen. The minimum ranges of navigation lights are defined according to ship size as follows::

Best-seller Hella Marine

Note: When sailing boats are powered by a motor, the rules for motorboats apply and not for sailboats. The tricolour light may then no longer be displayed.

Displaying lights for sailboats up to 20 m

1 x red port side light

1 x green starboard light

1 x stern light

Also allowed:

1 x red all-round light on or near the mast top

1 x green all-round light on or near the mast top

1 x 3-colour light

Sailing vessels under 7 m (dinghies or small sports boats)

If, due to their design, no modern lights can be fitted, sailing vessels under 7 m in length and vessels being rowed must always carry an electric torch or lantern showing a white light, ready to exhibit in sufficient time to prevent a collision.

1 x Electric light or a torch with white light

Motorised vessels over 12 m

Lights used must be either / or:

1 x white masthead light fore

1 x dual colour light

Motorised vessels under 12 m

Alternatively, motorised vessels under 12 m can exhibit the following lights:

1 x white all-round light

Motorised vessels under 7 m and 7 knots maximum speed (small motor boats, dinghies or inflatables):

Motorised vehicles under 7 metres and with a maximum speed of no more than 7 knots can display the following navigation lights: all-round lights, portside and starboard lights.

The following applies in accordance with German Traffic Regulations for Navigable Maritime Waterways (SeeSchStrO): If, due to their design, no lights can be displayed (e.g., dinghies), sailing vessels under 7 m in length and 7 knots maximum speed must carry an electric hand-held spotlight or a torch to prevent collisions in the dark.

Left: 1 x white all-round light, 1 x red port side light, 1 x green starboard light

Right: 1 x hand-held spotlight or torch

Best-seller Aqua Signal Conventional

Best-seller Aqua Signal LED

Provided no engine power is used, the rules for sailboats apply. Motor-sailing vessels must display a large black cone pointing downwards when sailing during the day or at good light.

For vessels travelling under sail or at rudder during darkness or at reduced visibility, the rules for carrying lights for motorised boats automatically apply. This then depends on the length of the boat.

By day with a black cone, tip pointing downwards.

Visual signalling equipment

Torches % Spotlights

How must navigation lights be mounted on board?

Navigation lights must be securely mounted perpendicular to the waterline. Mast-head lights and stern lights should both be placed above the keel line.

At anchor during daylight? This must be displayed with a black anchor ball.

If the vessel is anchored outside of an area of water known by the River and Shipping Police Authority as an anchorage and berth for small vessels, this must be indicated as follows:

A black ball by day, 1 x white all-round light at night

Anchor Lights

If your boat is unable to manoeuvre*, this should be indicated as follows:

Stationary: 2 x red all-round light, 2 x black ball, one below the other (during the day)

Moving: 1 x red port side light, 1 x green starboard light, 1 x white stern light

* A vessel is described as if, due to exceptional circumstances (e.g., rudder failure or engine malfunction), it cannot manoeuvre as prescribed and therefore cannot avoid another vessel.

How do I indicate correctly that my sailboat or motorboat has run aground?

If your boat has run aground, this should be indicated as follows:

2 x red all-round light, 1 x white all-round light, 3 x black ball, one below the other (during the day)

Manufacturers that specialise in navigation lights such as Aqua Signal or Hella Marine supply a wide range of internationally approved navigation lights which work with conventional (with BSH bulb) or with permanently installed light-emitting semiconductor components (LEDs). The bulbs required for operation are an integral part of the approval. Replacement bulbs must also be certified so that approval / your insurance protection is guaranteed. Ships under 20 m: Stern and anchor lights require BSH-approved light bulbs with 10 watts, all other navigation lights 25 watts.

All series listed above with BAY15d sockets could alternatively be operated with a high-Power LED . The big advantage in doing so is that the LED is suitable for multiple voltages (10-30 V) and consumes just 3 watts during operation. Since the light colour, range of light or beam angle can vary depending on the housing, this light is NOT yet internationally approved.

Spare Bulbs - Conventional & LED

Energy consumption on sailing ships is, as ever, a topic of significant interest. This is especially true for blue-water sailors who like to sail longer distances at a stretch. The arguments for converting to LED technology are as follows:

• High energy savings due to the low power consumption
• Long lifespan (over 10,000 hours)
• MultivoltTM technology (10-30V) with greater tolerance to voltage peaks
• Compact and light housing constructions
• Waterproofed, hermetically sealed housings
• Maintenance free

When switching completely from conventional navigation lights to LED lights, lights with the BSH seal of approval / EU wheel mark meet all the requirements in terms of light colour (no risk of blue tint), range of light and beam angle, and that you are travelling in accordance with KVR.

Navigation lights with LED technology

Replacing your navigation lights is often easy to do as manufacturers usually use the same mounting points for LED lights or have an adapter plate for further use of existing drill holes:

Ultimate Guide To Marine Navigation Lighting

If you drive a car or even ride a bicycle, you might be well aware of the necessity of lighting systems (though in the second case the word ‘system’ doesn’t quite apply) for the safety of you and the people around you. The thing applies just as well for ships. But since they are much larger than a car, the lighting system or navigation lights on ships is a little bit more complicated as well. Marine navigation lighting is also one of the most critical aspects of nautical studies.

It is mandatory for boats of all sizes to have a navigation system . This is to make sure that the chances of any significant accident are minimized. The United States introduced the system in 1838, and the United Kingdom followed suit. Before being internationally adopted in 1897 suitable guidelines were established by the International Maritime Conference which was established in 1889. Three colors were chosen that were to be used for the light colors. They were red, green and white.  This was based on a set of rules specified by the US and are followed around the world to this date.

This article discusses the different rules and regulations of using navigation lights, their importance, and also some basic marine navigation lighting systems along with their positions and ranges.

Marine Navigational Lights, Rules and Regulations

A standard pattern of marine navigation lighting is followed for the identification of both the vessel as well as the IALA buoyage system at night. If you are required to move from sea to a channel you need to have a list of all the IALA as well as the other fixed navigational lights that are visible on entering the channel. This includes distant lighthouses as well.

If you also make a note of the inland features like the radio and television transmitter masts it will benefit you because they act as good navigational aids due to their height and warning lights.

The helmsman should not be using any bright light source in the cockpit area and should rather take the aid of red lights and very dim white lights in the galley and navigation area. This is because he needs to preserve his night vision so that he can accurately interpret both the buoyage marine navigation lights as well as the boat navigation lights of other vessels.

The nautical almanacs contain the details of each and every visible maritime light signal coming from navigational markers that are both inside and outside the channel.

All the details about any particular light can be found in a published list or on a marine navigational lights chart: its color, period, and in some cases even the elevation and range of the beacon. Use the chart to keep a tag on the lights you are passing by putting a tick mark on the lights that you are about to pass and as the boat sails past, the tick is checked.

You will get two visual clues to figure out how far you are away from a buoy. The light will elevate from the horizon at 0.5 nm and at about 200m, the light will reflect on the surface.

Position of Boat Navigation Lights

Most of the variations that can be found in the different vessels can be read about in most almanacs. At the very basic level, a vessel needs to show a red light to port and green light to starboard. Depending on the size of the vessel, one or more colored or white lights are used as well.

For vessels that are 12 ft in length or shorter, the navigation lights must be visible from a range of one nautical mile and for the ones that are longer than 12 meters the required visibility range is 2 nautical miles.  From 5 degrees above to 5 degrees below the horizontal happens to be the required minimum intensity in a vertical sector.

International Navigation Rules state that the boat navigation lights should be placed above the uppermost continuous deck. In case separate fixtures are used for the red and green sidelights, the masthead or all-round white light is placed as close as possible to the vessel’s fore and aft centerline. The masthead or all-around light needs to be positioned at least 1 m or 3.3 ft above the sidelights.

Following are the basic positions of navigational lights. We will discuss the same in greater detail ahead.

Boat Navigation Light Regulations

Several rules and specifications are related to the type, size, layout, arc, and distance of visibility of boat navigation lights used by all vessel types which are collectively known as the International Regulations for Preventing Collisions at Sea or COLREGs . The navigational lights used are known as ‘COLREG lights and shapes. A boat might be anchored or underway, under sail or power, or fishing or trawling. These various situations can be communicated through multiple combinations of boat navigational lights.

In addition to the primary navigation lights, vessels may also display one or more steaming lights. These lights are very useful for it gives details about the various aspects of the ship like whether it is in the sail or under power, the direction in which it is going and, in some cases, even the size of the vessel. If a ship is engaged in a specific task that might involve certain restrictions, that too can be indicated with some extra boat lights.

Always maintain the lighting system and display the correct navigation light combination to make other vessels in the vicinity aware of your course and state as to whether your vessel is under power or not. If you follow this a considerable amount lowers the chances of a collision. Here is a list that you might use to familiarise yourself with the basics of the lighting system.

• Basic Navigation Light White Light : Small dinghies that are 7m or less in size are required to carry a torch having a white light that can be flashed when needed.
• All-Round White Light: An all-round white light is expected to be displayed by a small boat, up to 7ft long that is under power and can go beyond 7 knots of speed. This light must be visible at an angle of 360 degrees and from two miles away. An all-around white light is also used when the boat or vessel is at anchor but not at a designated anchoring area. This is to make sure that the ship is visible to all the nearby ships to avoid any accidents.
• Stern and Combined Side Lights : A stern light is a white light that is installed at the end of a boat.  A vessel that is over 7 m or 23 ft in length is expected to show red and green sidelights when sailing. Each of these lights needs to cover an arc of 112.5°. The sidelights may be combined in one lantern at the bow when below 25 m or 65 ft. The white stern light can be seen over an arc of 135°. These lights need to be visible from a distance of a mile and need to be placed 39 inches below all white lights for boats of lengths equal to or less than 12 ft.
• Masthead Light : A combination of sidelight and stern light in a tricolor combination may be used sailing yachts of heights 20 m or lower.  A masthead light is required by vessels of lengths between 39.4 ft and 65.6 ft. It is placed in the masthead whose height provides excellent visibility. Still, stern lights and sidelights should be fitted separately in case of or use under power along with steaming light. This kind of light needs to be visible across an angle of 225 degrees and from a minimum distance of 2 miles.
• Separate Lights : The displaying of the tricolor masthead light is not allowed in the case of yachts that are longer than 20 m or 65 ft. Instead, they use them separately. Often on large sailing vessels, these all-around, red over green lights are present. These red and green sidelights need to be visible from a distance of one mile and across an angle of 112.5 degrees.
• Steaming Lights Combined Lights : A combination of the masthead and stern light are used in the case of power crafts that are less than 20 m or 65 ft in length. The arrangement is present at the bow.
• Single Steaming Light : Visible over a 225 degrees arc, a masthead steaming light is used by power-driven vessels that are up to 50 m or 160 ft long. Separate stern lights and sidelights are used in case of a length exceeding 20 m or 65 ft.
• Two Steaming Lights: Power-driven vessels that span over 50 m or 160 ft in length display two masthead steaming lights. The forward light placed lower than the aft light with both of them being visible over an arc of 225° with the sidelights and separate stern light.

The area of the nautical lighting system is a precise business and requires some amount of study and a good deal of responsibility. It is because its application forms a core element in safe marine navigation.

CG regs for Steaming Light on 32 ft sailboat

• Add to quote

My 15 year old Hunter 326 does not have a steaming light but does have side and stern lights...as well as an anchor light. I am under the impression a sailboat this size does not require the steaming lite....previous owners obviously thought so too. Question is if I am under power at night should I use the anchor lite at the top of mast as a steaming lite?  

Did it have a "Steaming light" previously..?  

I'm no expert, but with the addition of the anchor light, you would be showing two white lights when viewed from astern. My 40 year old Bristol has a steaming light and I use it. Ken  

I believe, if the boat is under 12 meters (39ish feet) a single all around white light can be substituted for the forward facing masthead (steaming) and aft facing stern lights. If you think about it, when removing the forward and aft facing white lights, the all around is going to look the same from every angle.  

If you put in the query you will find that you are fine ! Regs require steaming on 20m and over !  

CarbonSink is correct. Being rather confusing to anyone overtaking you, I should think that puts the burden on you to make sure the overtaking vessel is not hampered. Rather a daunting thought, should that vessel be running at 15 to 20 knots, or more.  

You would simply extinguish the stern light, to avoid confusion. A stern light is not required, I believe, if you use an all around white light, for a boat of that size.  

Minnewaska said: You would simply extinguish the stern light.. Click to expand...

Your boat would have been built with running lights (sidelights and a sternlight) and a switched steaming light. Hunter often has a rocker switch - when set to power the steaming light is on, when set to sail it is off. Trying to use an an anchor light in place would be an all around bad idea. You would need to switch the stern light so you could turn it on when under sail, with the anchor light turned off.. Finally in close quarters in a crowded harbor, a running light located at the top of the mast is asking for trouble...it might meet a strict reading of the rules, but the insurance companies will give you 100% of fault just the same.

Interesting discussion. I would have bet money a masthead light (the term "steaming light" doesn't appear in ColRegs) was required on a boat that size, but as usual Minnewaska is correct that a vessel under 12 Meters (~39') can show an all around white plus side lights. I do believe the Regs require one or the other and that displaying an all around white at the masthead and a stern light would not be legal as it would create the impression of a head on situation with a large vessel (upper and lower masthead lights) with no side lights. If the boat was built to this reg, I would expect the stern light would be on its own switch to allow stern and sides under sail and all around white plus sides under power?  

I believe you have two choices Under Power: Under 12 meters and under 7 knots, you can show an all around white light. or You can display an all around white light and side-lights. ( with no stern-light) How you accomplish that with switching, is up to you.  

COLRegs specifies requirements that a vessel operator must meet, but it does not attempt to prohibit every possible dumb but conforming idea that a creative human might think of. No regulations limited to a few hundred pages can do that. Should the PO follow the woeful advice offered here, consider his discussion with his insurance company following the accident: Insurance: the other boat says they hit you because your stern light was out and they did not see you. PO: Sure, I turned the stern light off, but I had my anchor light on instead. Insurance: Why would you do that? PO: Because ColRegs doesn't say that I can't do it? Insurance: Are you kidding? You get the 100% fault. Remember accidents can involve more than just boat damage, people get injured also. Perhaps another thread on the question whether the PO's action in the described situation would qualify as willful negligence in a criminal case. See Fatal boat crash: Wrong man charged? | abc7news.com  

Insurance: the other boat says they hit you because your stern light was out and they did not see you. OP: Sure, I turned the stern light off, but I had my all-around white light on instead. I also had my sidelights on. Insurance: Why would you do that? OP: Because ColRegs Rule 23 (d)(i) reads as follows: "A power-driven vessel of less than 12 meters in length may in lieu of the lights prescribed in Rule 23(a) exhibit an all-round white light and sidelights." I was under power and my Hunter 326 is 32 feet in length, which is less than 12 meters. https://www.navcen.uscg.gov/?pageName=NavRulesAmalgamated#rule23 Edit: fixed cut and paste and added link  

If it were me, I'd have a Steaming Light installed. However, Steaming light, anchor light or stern light, not much is going to save someone from an idiot going 50 miles an hour up your butt.  

Understand that Hunter shipped the boat with an installed steaming light. The OP just needs to repair it, or install a replacement fixture it the OEM has been ripped from the mast. Sent from my SM-G965U using Tapatalk  

My understanding is that the masthead light with sidelights is legal. However, as some have said, I was never comfortable having the stern light off for fear of being hit from astern by someone not noticing the light at the top of the mast. My solution was a masthead light with separate fore and after sectors. At anchor, both on, steaming at night, only front on (with other nav lights unchanged).  

We, who sort of understand running lights and what they are supposed to symbolize (which puts us in the minority after dark, I'm pretty sure), are getting all wrapped around the axle about what is and isn't a 20-point white light showing forward when our sailboat is under power. I have, on small no-electricity sailboats when out after dark, used battery-powered red-green bow light combo forward, and a dive light with a taped-on "dome" made out of wax paper or other translucent stuff, and lashed onto the top of the tiller or rudder, as a sort-of stern light. When little outboard gets put into gear, I will typically add a similar jury-rig flashlight white light onto the mast, jammed under a tight spinny or jib halyard, as an "I'm under power" forward (steaming) light. None of these are visible three or five miles, more like a mile I would think. But it's something, I'm usually close to the harbor, and it's good practice. What's the point?? If I see just red and/or green, or both, somewhere ahead, I think "sailboat"! If I also see a white light higher up, but not atop Mount Everest, I think "powerboat"!! And if I see just a white light, I think "okay, some kind of boat, going away from me, or a small dinghy or whatever with a single white light. An anchor light way up on the masthead as a "steaming" light, at least at close quarters, looks weird to me. I wonder if it's a sailboat at anchor, or if I see red or green, if he's sailing and using the masthead light to see his telltales, or what? Or, is he anchored and forgot to kill the red/green? Or just confused about lights and figures "more is better"? It's easy to overthink, more so at night. True of more than just sailing ;-)  

I believe you are correct. We have a three way switch. Off; sailing w R/G and W stern light; steaming w R/G and all around masthead with stern light off. Of course, under 7 meters, we could be legal with a readily available lantern.  

Sail a lot at night. Nice to landfall the next island at daybreak. Also of course on passage. Something Capta said perks my interest. From the deck of my boat I can’t see another sailboats running lights once they’re a few miles off. If there’s a sea running they need to be even much closer. But if they have their masthead tricolor it’s rarely an issue. So coastal we use the deck lights but offshore the masthead. From what Capta says we may have this backwards. Now I figure ships will spot us on radar and AIS (if anyone’s looking) so issues of course and vog are moot. But rather the issue is small craft. A lot of cruisers may not have AIS or their radar may not be on. It’s them I want to see and want them to see me. Been with people who scan the 360o every 10 to 15minutes especially when offshore. Want to give them several chances to see me. I’ve had occasion to vhf call multiple times and finally get a response when doing a busy jump(Gorda-st.martin when it’s been awhile to get a window). We wanted to go to Marigot, they seemed to be heading for the Dutch side so we would cross. Finally saw a head peak out the companion way. He saw me then veered off for a bit allowing me to cross his bow without tacking or luffing until he passed which was gentlemanly. I was burdened being the overtaking vessel. We were both on port tack. Now his deck lights weren’t seen until we were close and even then were blinking. So think the tricolor may be safer overall in some circumstances.  

If you want to be seen by a particular nearby boat/tug/ship who's not that far away, a big bright flashlight shone onto your mainsail or jib and waved around, will be way more effective than any of your wonderfully correct running lights. Most vessel to vessel tangles at night are not caused by misapprehension of nav lights. Rather, it's by "*&%#, I never saw him"---/or/---" he never saw me"...  

Sidelights are red (port) and green (starboard) and shine from dead ahead to 112.5° aft on either side. Stern lights are white and shine aft and 67.5° forward on each side. (Thus, the sidelights and stern light create a full circle of light.) All-round lights are white and shine through 360°. Masthead lights are white and shine from 112.5° on the port side through dead ahead to 112.5° on the starboard side. They must be above the sidelights. Sailboats under power are considered powerboats. Sidelights may be combined into a single "bicolor" light. Powerboats less than 20m (65.7') in length need to show sidelights, a stern light and a masthead light. Power vessels less than 12m may show a single all-round light in lieu of the separate masthead and stern lights. Sailing vessels less than 20m in length need to show sidelights and a stern light. These may be combined into a bicolor light and stern light, or a single tricolor light at the top of the mast. Sailing vessels under 7m must have an electric torch or lantern available for collision avoidance. Oar-driven vessels can show either the sailboat lights, or use the electric torch/lantern option. When anchored outside a special anchorage, power and sail vessels under 20m must display an all-round light. Vessels under 7m are exempt, unless anchored in a narrow channel or anchorage, or where other vessels usually navigate. Sailboats with sails up during the day, but which are also under power, must fly a black "steaming cone," with its point downward, where it can be seen. When under power they must follow the rules of the road for powerboats. Notes Boats under power under 40' can substitute a single all-round light for separate stern and masthead lights Boats under 65'7" can substitute a single bi-color light for sidelights Sail boats under sail under 65'7" can substitute a tri-color light for separate sidelights and stern light.

Keep a dive light in the cockpit to shine on the sails but mostly for checking trim. The shining on the sails bit is fine if you have nothing else to do and the other idiot is looking at your sail when you’re shing the light. I’m not going to be doing that for hours on end and often have other stuff to do. Nor am I going to wake someone up to do it. So don’t think that’s a practical answer except in certain limited circumstances. In the example above passed at least 1/2 dozen sailboats and was passed by another 1/2 dozen. Also several of those small tramps with the deployable ramps up front and two cruise ships. In those circumstances putting the spreader lights on briefly makes more sense. Light rules be damned become a fish boat for awhile and light up the world. Still like opinions on: When’s best to use your deck lights? When best to use the tricolor? BTW- get a steaming light. What’s legal and what’s wise are two different things. Same as what’s legal and what’s just.

I will add that the steaming light on the Hunter 36 that I used to teach on was at the very top of the mast, and shined through an arc of 225º. If one flicked on the anchor light, then the same fixture illuminated a 360º arc. I hated that setup because you couldn't see if either of these lights worked from the dock during daylight. I believe that the anchor light actually powered up two incandescent bulbs, thereby drawing twice the power when you were at anchor.  

This has been a rather... ...amazing "discussion". It's almost as bad as a stand on vs. law of tonnage discussion. Follow the rules or avoid the Salish Sea, please.  

I don't claim a ton of night sailing experience but the night experience I do have has been in the presence of a lot of other sailboats. For the most part I've witnessed deck level nav lights or masthead tri-color, properly displayed with judicious use of white light on the sails from time to time. I've also see a lot of dorked up stuff like sailing with the anchor light on presumably to illuminate a masthead fly. I've also seen careless handling of billion candlepower spotlights to illuminate telltales, but lighting up the cockpit of every other boat within 3/4's of a mile. In my experience the most difficult vessels to pick out nav lights I've ever encountered have been tugs and cruise ships that were displaying so many white lights on deck it took many minutes of observation with binos at night before being able to pick out the nav lights. In the case of the tug, I couldn't see the red or green until I was seeing both, fortunately at some distance and because he was changing course to exit the bay.

Not that it has too much to do with the discussion, but anytime I've been anchored in an area where I felt at all at risk of being run into at night, I would leave my foredeck and cockpit courtesy lights on in conjunction with the anchor light. Lit up the boat like a little floating city and made me worry a little less when woken up by the sounds of motors approaching.. LEDS are great...  

The " Rules" seem to have stood the test of time. 46 years, I believe that they're pretty well thought out.  

Your test of time is a test of enforcement, not law, morality, value or any other version of right and wrong. You can make smoking in a no smoking area a felony, if you have the enforcement.

USCG Navigation Lights Requirements

• By Boating Staff
• Updated: November 2, 2017

Powerboats under 12 meters (39.4 feet) in length must have separate or combined red and green sidelights covering 112.5 degrees and visible for 1 nautical mile. The white masthead light must cover 225 degrees, be 1 meter above the sidelights and be visible for 2 nautical miles. The white stern light must cover 135 degrees and be visible for 2 nautical miles, or you can substitute one 360-degree all-around white light. For larger boats, the sidelights must be visible for 2 nautical miles and the masthead light for 3 nautical miles.

Navigation Lights at Night

Great article! Boat lights are the means of communication between sailing vessels. These lights are also a tool to let my presence known even from a distance.

yet another nav light question

• Thread starter kpgraci
• Start date May 15, 2014
• Forums for All Owners
• Ask All Sailors

The COLREGS offer a variety of options for navigation lights on a < 12m sailboat, but as I already have colored sidelights on the bow and a white stern light, all I need is an anchor light and a steaming light. So as I read the COLREGS navigation lights requirements I see rule 23 d(i) says in lieu of a masthead and stern light an all-around white light can be used on power-driver vessels <12m. This is actually what I see on most motor boats. So if I add a simple all-around white light to the top of my mast it would act as an anchor light if I turn the other lights off, while sailing the bow and stern would be on and the all-around off, and when motoring under rule 23 d(i) I could turn on the bow lights and all-around and turn off the stern light. I would use a 4 position rotary switch to select the proper light combinations of Off, Sailing, Steaming, or Anchored. Having never seen this setup it makes me wonder where am I going wrong?  

Charlie Jones s/v Tehani

Can't comment on the rest, but up at the mast head is THE worst possible place you can put an anchor light.. You want an anchor light to be seen by others in small boats, and early morning fishermen are NOT looking up that high. It would be easily seen from a ship, but personally, I don't anchor where ships move around. I hang mine from the backstay, up above boom height.  

Rather than mince the COLREGs, you should always have your red/green on at night. It gives other boaters awareness of your direction of travel and distinguishes you from the clutter of white lights. If motoring you need to show a white steaming light in declaration of your RoW status. Masthead lights can be difficult to see, especially close in...where you really need situational awareness  

I may be mistaken, but isn''t there a requirement that the anchor light must be visible from a certain distance, but only if you are anchored. I do not think there is any requirement for a steaming light...bow lights and stern light are all that are required for a vessel under 26 ft. I believe....I don't think there is even a requirement for a masthead light in vessels under 26 or 27 ft. I may be incorrect. I will check Chapman's before the day is over. My 272 came with what is called anchor and separately, a steaming light, but the steaming light never has worked..... maybe I'm in violation when motoring or sailing across the lake because I use the bow, stern, and anchor light only...I turn off the running lights when anchored.  

Stu Jackson

I think you're unnecessarily complicating things. The "masthead" light is often confused with the "steaming light" usually mounted on the forward side of the mast around spreader height. Don't use an all around white light at the top of your mast unless anchored.  

Another option is that you could install a mast light that has both the "steam light" and and the all around anchor light built into it. Use the steam light with your existing stern light, and light it all around for the anchor light. Out boat has an led light that does both. It's nice and bright. You don't overlook us in an anchorage. Like fig 1 and fig 7 here: http://www.boatingbasicsonline.com/content/general/4_2_b.php  

Be sure to compare the current draws for each configuration. At anchor and under sail you will be on batteries, when under power you have a basically unlimited current supply so don't care how much current that configuration draws. FWIW  

The anchor light needs to provide 360 degree illumination while the steaming light is less than 180 degrees. Show your stern light when navigating at night. Both the steaming light and the stern light will provide indication of direction of travel. A single light cannot do that.

With a small sailboat, to keep it simple, 4 lights and 3 switches. Port and starboard bow lights, stern light and all around white light at top of mast, each on its own switch. With this setup you can be legal in all situations with the minimum equipment.

This is not exactly what you asked about but you did day your light stopped working. For an anchor light, a nice camping LED hung from the boom works. And IMHO is a lot safer. In a fog no one is going to see your puny little light at the top of the mast. And when the camping light starts to act up, you replace it without having to climb the mast. And you don't have a through deck connection to make. It is simple, it works... I have a light at the top of my mast, it still works but I don't use it. I don't want to draw down my house battery. My LED camping lantern I got at WalMart. It will work for 5 nights on a single set of batteries. And It does a great job of lighting up the cockpit. We sit out and play cards.

My LED camping lantern I got at WalMart. It will work for 5 nights on a single set of batteries. And It does a great job of lighting up the cockpit. We sit out and play cards. Click to expand

Man, that IS a nice looking German built lantern. And I like that description, "older shippy looking boats". Pretty cool..  

On the O'Day 272, the mast light(s) are both at the top of mast..the switch can be set to either anchor or steaming....but not both at the same time I assume...and in our case the steaming light has never worked...so we use the anchor light after dark...my point is that I don't think any masthead light is required in a boat under 26 ft...unless you are at anchor.

This is of interest as always because a stationary barge by the tappan zee bridge was struck in 2013 with fatality's And of course almost instantly the legality of its lighting was front and center no matter the BAC level of the boats operator and it is still and active court case

Anchor Light Requirements

USCG anchor light requirements for inland waterways.

Advertisement

The Inland Rules have specific requirements as to anchor lights. That rule is quoted below, as is the USCG site reference.

A 360-degree white all-around masthead light with two-mile visibility normally fulfills this requirement for most pleasure boats, but familiarize yourself with and follow the rule. Wire gauge, length of wiring, connections and battery condition can affect a light's performance. Follow manufacturer's instructions to ensure compliance with U.S. Coast Guard regulations. If you have one of the newer LED anchor lights, it may not be as bright as earlier lights. Be sure that the manufacturer specifies in writing that it meets USCG requirement.

Displaying a proper anchor light when anchored at night isn't merely a matter of law. It's a matter of safety for you and others. Even if the boat is in a known or designated anchorage area, dinghies and other boats may be traveling in that area and will need to know the location of your boat. People have been severely injured and killed because a skipper decided that he'd not burn an anchor light.

Following is Rule 30 of the Rules found here .

Rule 30 - Anchored Vessels and Vessels Aground

(a) A vessel at anchor shall exhibit where it can best be seen:

(i) in the fore part, an all-round white light or one ball;

(ii) at or near the stern and at a lower level than the light prescribed in subparagraph (i), an all-round white light.

(b) A vessel of less than 50 meters in length may exhibit an all-round white light where it can best be seen instead of the lights prescribed in paragraph (a) of this Rule.

(c) A vessel at anchor may , and a vessel of 100 meters and more in length shall, also use the available working or equivalent lights to illuminate her decks.

(d) A vessel aground shall exhibit the lights prescribed in paragraph (a) or (b) of this Rule and in addition, if practicable, [Inld] where they can best be seen;

(i) two all-round red lights in a vertical line;

(ii) three balls in a vertical line.

(e) A vessel of less than 7 meters in length, when at anchor not in or near a narrow channel, fairway or where other vessels normally navigate, shall not be required to exhibit the shape prescribed in paragraphs (a) and (b) of this Rule.

(f) A vessel of less than 12 meters in length, when aground, shall not be required to exhibit the lights or shapes prescribed in subparagraphs (d)(i) and (ii) of this Rule.

(g) A vessel of less than 20 meters in length, when at anchor in a special anchorage area designated by the Secretary, shall not be required to exhibit the anchor lights and shapes required by this Rule. [Inld]

For sailing we carry a tricolour light at the top of the (the requirement is for Sidelights and Sternlight, the note allows for these to be combined into a tricolour light atop the mast). So under sail, only one light (red, green or white) is visible to an outside observer. So far so good. For motoring/steaming/motorsailing the is considered a . The requirement is Sidelights, Masthead light and Stern light. Sidelights may be combined into one fitting, masthead and stern lights may be combined into a all around white light. So to an outside observer only a white light is always visible except when viewed from dead ahead to 22.5 degrees abaft of beam, when a green OR red light would also be visible. Yes? If I already have the tricolour light at the top, what is needed to complement this for motoring? Is another set of green/red sidelights needed at the bow? I would think not because the Tricolour already displays the red/green. Is an additional masthead light what is needed (to display white all around when combined with the white on the tricolour)? Could this masthead light be installed below the tricolour? I am sure I am overcomplicating this and the answer is simple and straightforward, only that it is eluding me. I have the tricolour top of mast, good for sailing. Need to know the simplest light addition to comply when motoring. Many thanks to those with a clear and unambiguous grasp of the requirements to help clarify them for this particular situation. 11-06-2020, 06:44   Boat: Island Packet 38 is the front of the mast, so you need a steaming light to be on when under mounted to the front of the Mast. Otherwise you could turn on your Tri-color and light. And then for reasons I’m not sure of apparently the streaming light shouldn’t be below the red/green, meaning as I understand it that a Tri-color is not appropriate for running under . Which takes us to requiring the normal running lights to be run under power with a steaming light on. 11-06-2020, 06:45   Boat: FP Belize Maestro 43 and OPBs level side lights and a sternlight. These need to be on a separate circuit to the tricolour at the top of your mast since the tricolour should not be on when the "motoring lights" are on and vice versa. The level sidelights may be a combined light on the centreline of the vessel (not necessarily at the bow - although that is a good idea if you are also using them when under sail to avoid them being covered by the headsail) or separate lights on either side of the vessel, 11-06-2020, 06:52   Boat: ‘01 Catana 401 If not, here it is. Notice the sailing requirements are for either tricolor or deck level, not both. Also you cannot use the tricolor under power. 11-06-2020, 06:57   11-06-2020, 06:57   Boat: Amel 53, Super Maramu you are looking at. If you are lit with a tricolor at the top of the mast, and a steaming light BELOW it you are NOT showing the lights appropriate to a motorboat. A WHITE light OVER a GREEN light is the port beam of a motorboat underway. A GRREN light OVER a WHITE light is a vessel that is trawling, and not making way. To present one example of why the vertical orientation of lights is more important than many people seem to think A pet peeve of mine is that this configuration of tricolor at the top of the mast, a steaming light below it, and NO deck level lights is how many cruising catamarans are delivered from the factory. Somehow they manage to get an EU with this combination of lights that makes it illegal to at night. 11-06-2020, 07:00   Boat: FP Belize Maestro 43 and OPBs 11-06-2020, 09:30   Boat: 35ft classic ketch/yawl. and visibility. Many use a combined red/green on the pulpit or separate red and greens on the bow. Both of these are very vulnerable to both getting knocked when and being regularly dunked in seawater. The other factor is that steaming lights are frequently used in harbour with lots of shore lights around. Anything up the mast tends to get against that background. Deck lights show much better, particularly from the bridge of a ship, when lower so seen against the black . This is why, particularly on larger side lights are often mounted in boxes on the shrouds or top.

Boat Navigation Light Rules Explained (For Beginners) Boat navigation light rules can be a little difficult for newcomers to understand.  This is probably because these light rules can change depending on a wide variety of factors. Failing to comply with these rules can leave you open to enforcement violations as well as lawsuits.  Also, knowing these rules will help keep you and other boaters safe while out on the water, so you must learn and remember them. Here’s everything you should know about the boat navigation light rules. Table of Contents Why Have Boat Navigation Light Rules At All Boat navigation light rules help boaters communicate with each other.  They also help to determine who has the right of way.  This is important as it determines what actions boats will take as they pass one another. Without these guidelines, there would be many more accidents out on the water as people wouldn’t know how to interact. Remember, when you’re out on the open water, there aren’t any designated lanes to follow, and without rules, boaters can easily become confused about which way they should turn or whether or not they should even turn at all. On top of this, these rules help establish methods for boaters to tell each other when they’re anchored or when they’re in distress.  Use your lights correctly when you need help, and you’re much more likely to get it. When do I Need to Follow Boat Navigation Light Rules? Light rules apply any time between sunset and sunrise.  They also apply any time visibility is low. An example of this could be during foggy or rainy weather. A more unusual example of this could be during a solar eclipse.  Basically, if you feel that having the lights on will help others see you better, it’s a good idea to turn them on. The Different Light Rules by Boat and Size Different types of boats will have different light rules that they need to follow.  These sets of rules are broken down based on whether the boat is a sailboat or a powered boat. Once this is established, the rules are then broken down by size. The different sizes to consider are boats shorter than 39.4 feet, boats sized between 39.4 and 65.6 feet, and boats greater than 65.6 feet. If you’re wondering why the numbers are so precise, it’s because this is the conversion from meters.  39.4 feet equals 12 meters, and 65.6 feet equals 20 meters. Generally, all boats will have a red light on their port side and a green light on their starboard side.  To put it in plain English, if you’re in the driver’s seat, the red light goes on the left, and the green light goes on the right. A white light should be at the stern of the boat.  The stern is the rear of the boat. Powered Boat Light Placement Here are the lights you’ll need when operating a powered boat, depending on the size of the boat you’re operating. Boats less than 12 meters or 39.4 feet long: You’ll need one red light and one green light at the front port and starboard sides of the boat for these boats.  These lights should be positioned so that they can be seen at an angle of 112.5 degrees.  The sidelights should be strong enough to be seen from a mile away. You’ll also need to mount them towards the bow of the boat.  This is otherwise known as the front of the boat. Additionally, you’ll need one white light that can be seen from all angles.  It should be strong enough to be seen from two miles away.  This light will need to be mounted at least 39 inches or 99 centimeters higher than the red and green lights. Boats greater than 12 meters or 39.4 feet but less than 20 meters or 65.6 feet: With boats of this size, you’ll still need your red and green lights, but your white lights will change. In this case, you’ll mount a red light to your port or left side and a green light to your starboard or right side. These lights will need to be seen from an angle of 112.5 degrees, and they’ll need to be seen from a distance of one mile. The two white lights will need to be mounted at the stern and masthead of the boat.  Stern lights can also be referred to as the aft light.  Either way, it just means the light at the back of the boat. This light will need to be seen from a 225-degree angle facing the rear.  It needs to be strong enough to be seen from 2 miles away. The masthead light is at the forward position of the boat.  This light is mounted on the masthead, and it must cover a 135-degree angle. The light will need to be visible from 2 miles away. Masthead lights must be mounted at least 8 feet above the gunnel.  The gunnel is the top edge of the side of the boat. Boats larger than 20 meters or 65.6 feet long: To operate a non-commercial boat over 20 meters or 65.6 meters long, you’ll have to have the same lights in the same positions as the smaller boats.  However, you’ll also need to add matt black inboard screens to your sidelights. Sail Boats and Other Unpowered Boats These boats can be broken down into two different size categories. These two categories are under 23 feet or 7 meters and boats that are over 23 feet or 7 meters. Unpowered boats such as sailboats, rowboats, and kayaks under 23 feet in length only need to have a white light on them.  This white light can be anything from a flashlight to a lantern. However, you can still opt to place red and green lights at their appropriate places. Larger sailboats will need to have a 135 degree white light at the stern and 112.5 degree red and green lights at the port and starboard sides.  The white light should be visible from 2 miles away, while the red and green lights should be visible from 1 mile away. Alternatively, a tri-color light could be placed on the masthead. This light will have all three lights built into it, and it should be visible from at least 2 miles away. Advice For All Boats Regarding Light Regardless of what boat size you’re on, it is a good idea to have a flashlight with you. If your boat lights become inoperable, you’ll at least have one light that you can signal with. Should you find yourself on the water at night in a disabled boat , your flashlight may be the only thing keeping you from being crashed into. Light Rules For Boats at Anchor When you’re anchored at a marina or dock, you won’t have to worry about specific boat light rules and regulations. However, when you’re anchored out on the water, you must follow boat light rules as this will help keep other boaters from running into you. It will also help establish that you have the right of way so you won’t have to move every time a larger boat comes your way. Of course, having the right lights doesn’t mean you’ll be able to anchor just anywhere.  You’ll still have to follow any inland rules when it comes to anchoring your boat. When anchored, you’ll need to display an all-around white light that lets other boaters know your position.  This light should be placed where other boaters can best see it.  For example, a sailboat might put this light at the top of its mast. Also, another all-around white light might be placed near the deck to help identify your anchored boat to nearby boats. Boats Under Distress Boats under distress should display what is known as a visual distress signal so that they can get help.  At night, these distress signals will come in flares, parachute flares, and lights. You should have at least three devices on your boat to use for signaling.  This could come in a variety of forms, and you can use the same one three times.  For example, your three devices could be having three signaling flares with you. Only use these lights when you’re in danger.  Failure to do so can result in heavy fines and potential imprisonment. Determining Who Has The Right of Way When you come across another boat, and you can only see a white light, then you’ll know that you’re either approaching an anchored vessel or a vessel that is moving in front of you.  In this case, you can overtake them and go around them from either side. If you come across a green light and a white light, then you have the right of way.  In boating terms, this means that you are the stand-on vessel. Technically speaking, the other boat should give way, and you won’t have to worry about changing your course.  However, there is always a chance that the other person will not give way for some reason, and you should be ready to move.  You never know, the other boater may not see you, or they may not know the rules as they should.  Remember, being right won’t mean anything if you end up dead in a boat crash. If you come across a red and white light, you are the one that needs to give way.  In this case, you’ll want to slow your boat down and pass by them, probably behind their path. In all of these scenarios I described, you were in a powered vessel, and you were passing a powered boat or a sailboat that was driving while under power. However, what happens when you encounter a sailboat or other unpowered vessel in a powered vessel? In this case, you’ll see a red light, a green light, or a white light, but you won’t see all three.  Regardless of what you see, you’ll want to give way.  This is because these boats can’t maneuver as well as you, and they probably won’t be able to get out of your way before you come across them. At this point, you can see why different boats need different types of lights and why it’s important to use the lights that apply to your particular craft.  Use the wrong lights, and you’ll confuse the other boaters around you.  This could easily lead to an accident that could have easily been avoided. What About Boaters Who Are Color Blind? Unfortunately, people who are color blind won’t safely operate a boat at night by themselves. Also, they won’t be able to get a captain’s license as you need to pass a color blind test to get this license. Here’s an article we wrote about all you need to know about boat license types (with prices) . If you’d like to do some recreational boating at night, but you can’t differentiate between the colors red and green, you might want to consider bringing a friend along. This way, your friend can tell you what colors you’re coming up on so that you can safely navigate yourself past other boats. 4 Types of Boat Lights The red and green lights that go on the sides of a boat are known as sidelights. White lights that only face backward are known as stern lights, and white lights that face forward are known as masthead lights. An all-round white light is a white light that faces 360 degrees.  These lights are used on smaller boats and on boats that are at anchor.  They can be replaced by making use of a stern light and a masthead light. Another type of light is the tri-color light.  A tri-color light can be used on a sailboat to portray the white, green, and red lights. Bi-color lights are also available for small powered boats and sailboats.  These lights display both red and green light. The combination of lights that are displayed will always give the boater a 360-degree field of light. This ensures that other boaters can see them no matter where they are in relation to each other. Safety Precautions To Be Aware Of Even new boats can have lights that weren’t configured correctly or lights that don’t work. It’s important that you check these lights before you head out on the water. This is true even if you don’t intend on staying out after dark.  After all, it’s always possible that you could become stranded until after dark or that it could become too foggy to operate out on the water without lights. Other Things You Should Know About Boating At Night Boat navigational light rules are critical for nighttime boating, but there are other things to consider as well. One thing to consider when boating at night is the use of a lookout. Having one of your passengers act as a lookout will make it more likely that you’ll spot problems in advance. Remember, other boaters aren’t the only potential hazards you can run into at night.  Shallow shipwrecks, low water depths, and unlit piers, docks, and jetties can also become hazards if they aren’t noticed in time for you to avoid them. High beams should be used for docking purposes only.  This is because using them while on the water can confuse other boaters. Also, the high beams can shine into other sailor’s eyes and can give them night blindness. Just think about it this way. It isn’t safe to drive towards another car with your high beams on, so why would it be safe to drive towards another boat with high beams on? Driving Speed Nighttime boating should be done at slower speeds than day time boating.  The primary reason for this is that visibility is more limited at night. Driving slower will help to give you more time to react to boaters and other hazards. When you first start boating, you’ll still have to take a moment to think about the lights you see.  Driving at a slower speed will give you this additional time without affecting your safety. Not All Lights On The Water Are Boats! I’ll end this post with a funny story I once heard about a boat traveling at night.  This story has changed many times over the years, but the gist of it’s still the same. It goes like this: A large vessel was traveling at night when they came across a white light in front of them.  The ship captain immediately got on the radio and contacted the other vessel to demand that they get out of the way. The other vessel responded by telling the captain to change his course.  To this, the captain responded with, “This is the warship, the USS Enterprise, and I demand you change course, or we’ll be forced to take action!”. To this, the other vessel responded with, “This is a lighthouse, and you are on course to become shipwrecked.”. This isn’t a real story, and now that you know proper boat navigation light rules, it is a story that could never happen to you.  If you came across a white light and thought it was a boat, you’d assume it was unpowered or at anchor, and you’d take steps to go around it.

Pontoon Boats Personal Watercraft nauticalknowhow Nautical Knots Tools and Calculators Understanding Boat Navigation Lights Boat navigation lights are essential when you’re out on the water. They’re essential, but it’s easy to misunderstand their uses and correct placements. If you don’t know the correct placement for your stern lights or know what type of navigation light you need on your mast, don’t worry: we’re here to help. Below, we’ve got an overview of everything you need to know about boat navigation lights: what type of navigation lights you need, where to put them, and why you need to use them. So without further ado, let’s learn more about boat navigation lights. What navigation lights are required on a boat? The U.S. Coast Guard Navigation Rules, International-Inland encompasses lighting requirements for every description of watercraft. The information provided there is intended for powerboats and sailing vessels less than 20 meters. The various options are illustrated. The U.S. Inland Rules apply inside the demarcation lines at the entrances to inlets, bays, rivers, etc. The demarcation lines are shown on coastal charts as magenta dashed lines. Once outside of the demarcation lines, International Rules apply. Powered Vessels Power boats less than 20 meters shall exhibit navigation lights as shown in Figure 1. (Note: 2 masthead lights are optional for vessels under 50 meters. Vessels over 50 meters will display two masthead lights.) Vessels of less than 12 meters in length, may show the lights in either Figure 1 or Figure 2. Powerboats less than 7 meters whose maximum speed cannot exceed 7 knots may exhibit an all-round white light, and if practicable sidelights instead of the lights prescribed above, in international waters only. Sailing Vessels and Vessels Under Oars Sailing vessels less than 20 meters may exhibit the navigation lights shown in Figures 3 or 4. Another option for sailboats is to use a single combination lamp at the top of the mast as shown in Figure 5. Sailing vessels less than 7 meters may carry an electric torch or lit lantern showing a white light to be displayed in time to prevent collision (see Figure 6 – left picture). If possible, the lights prescribed for sailing vessels less than 20 meters should be displayed. Vessels under oars may display the lights prescribed for sailing vessels, but if not, must have ready at hand an electric torch or lighted lantern showing a white light to be displayed in time to prevent collision (see Figure 6 – right picture). Small boats can benefit from using a temporary LED light with a suction cup attachment if permanent fixings aren’t possible. Shapes and Lights To alert other vessels of conditions that may be hazardous, there are requirements to display lights at night and shapes during the day. Anchored Vessels Powered vessels and sailing vessels at anchor must display anchor lights. An anchor light for a boat less than 50 meters in length is an all-around white light visible for 2 miles exhibited where it can best be seen (see Figure 7). Vessels at anchor shall exhibit forward where best seen, a ball shape (see Figure 8). Vessels less than 7 meters are not required to display anchor lights or day shapes unless anchored in or near a narrow channel, fairway or anchorage, or where other vessels normally navigate. Anchor lights are not required on vessels less than 20 meters, anchored in special anchorages in inland waters designated by the Secretary of Transportation. Sailing Vessels Under Power Vessels under sail also being propelled by machinery, must exhibit forward where best seen, a conical shape with the apex pointing down (see Figure 9). Vessels less than 12 meters are not required to exhibit the dayshape in inland waters. Sailing vessels operating under machinery, or under sail and machinery are considered as powered boats and must display the lights prescribed for a power-driven vessel. Restricted Maneuverability The Navigation Rules require vessels restricted in their ability to maneuver to display appropriate day shapes or lights. To meet this requirement, recreational vessels engaged in diving activities may exhibit a rigid replica of the international code flag “A” not less than one meter in height or at night display the navigation lights shown in Figure 10. This requirement does not affect the use of a red and white divers flag which may be required by state or local law to mark a diver’s location. The “A” flag is a navigation signal indicating the vessel’s restricted maneuverability and does not pertain to the diver. Navigation lights should be checked prior to departing the dock and you should always carry spare bulbs. The USCG doesn’t care if they were working when you left, only that they are working when required. Where do navigation lights go on a boat? The current navigation light requirements are found in the Navigation Rules, International-Inland, and in Parts 81, 84, and 89 of Title 33, Code of Federal Regulations . They’re easy to find, but many sailors and boat manufacturers do not have a good understanding of the rules governing the proper installation of navigation lights. To help clear up any misunderstandings here’s all you need to know: Sidelights that are installed in the contour of the bow without providing a mounting surface tooled to be parallel with the fore and aft centreline of the boat are not in compliance with the Inland or International Navigation Rules. Depending on the breadth of the boat near the bow and how far aft from the vessel’s stem the lights are mounted, this shift can be more than 20 degrees in some cases. Installing the fixtures too far aft of the vessel’s stem may result in the sidelights not being visible from a position dead ahead. Another factor in the proper installation of sidelights is that they must maintain their required minimum intensity in a vertical sector from 5 degrees above to 5 degrees below the horizontal. They must also maintain at least 60 percent of their minimum required intensity from 7.5 degrees above to 7.5 degrees below the horizontal. Installing flush-mounted sidelights, designed to be mounted to a vertical surface in the hull contour, without providing a mounting surface tooled to be vertical, shifts the vertical coverage sector. This also results in non-compliance with the Inland or International Navigation Rules. Additionally, most of these flush-mounted sidelights are installed below the vessel’s rub rail. International Navigation Rules require that sidelights be installed above the uppermost continuous deck. Therefore, this configuration would not be in compliance with International Navigation Rules. When separate red and green sidelight fixtures are used, the masthead light or all-round white light, whichever configuration is installed, must be located as close as practical to the vessel’s fore and aft centerline. For vessels less than 12 meters in length, the masthead light or round lights may be displaced from the fore and aft centerline providing that the sidelights are contained within a common fixture and mounted on the vessel’s fore and aft centerline. The masthead or round lights must be installed at least one meter (3.3 ft.) above the sidelights. Which navigation lights are you required to display when anchoring your boat for the night? Boating at night (or in reduced visibility) can present some special challenges. Not only is your depth perception lessened, but bright lights on the shore can also cast misleading reflections on the water and if you wear glasses, or worse yet bifocals, you simply don’t see as well at night as you do during the day. It is not only important that you be able to identify other vessels operating in your proximity, it is equally important that other vessels see you. Most recreational vessels are less than 30 feet in length and, according to the Rules of the Road, shall be equipped with navigation lights. These lights not only have a certain arc through which they can be seen but must be seen from a minimum distance. The following lighting requirements are for recreational vessels less than 12 meters in length. (approximately 39.4′) Masthead Light 225º White 2 Starboard Side Light 112.5º Green 1 Port Side Light 112.5º Red 1 Stern Light 135º White 2 The arc of the lights and color allows you to determine the direction a boat is moving. How good are your boat’s lights? You should test them to check your nighttime visibility, or you might land yourself in hot water with the Coast Guard. Whether on a trailer or at the marina, switch on your lights and see how well they can be seen. Walk away from the boat or row away, if you are at anchor or at a mooring, and see how visible the lights are as you move further away. How easy are they to see against the background of lights onshore? Does your stern light shine dead astern over the required 135º arc or does it shine to one side or up or down? Can it be seen from the required 2 miles and why is that important? As an example, let’s say that your stern lights can only be seen for 1/2 mile. You are underway at 8 knots and a large ship is approaching at 15 knots. The ship is only 4 minutes away from a collision with you. By the time the ship “might” see you, identify the light, and decide on how to move, it is too late. A ship traveling at 15 knots may take miles to stop. Look at the stern lights again, as you move from the stern toward the bow, does the stern light “disappear” as the sidelight “appears”? The stern light should disappear and sidelight appear at 22.5º abaft the beam. If you don’t see the green starboard sidelight or the red port side light when the stern light disappears there is a problem with the arc of one or all these lights. This means that if another boat were approaching you at the angle where no lights are seen there is an increased risk of collision. If both the stern lights and side lights are seen brightly at the same time you still have a problem. A boat approaching won’t know whether they are overtaking or crossing and whether they should give-way or stand-on. You should also check to make sure that your masthead light disappears at the same time each side lights disappear and they both disappear when the stern light appears. Check your sidelights from dead ahead. You should see both red and green. However, by moving toward one side just 1-3º you should then see only one light. If you still see two lights, an approaching boat won’t be able to tell which direction you’re are going. It is very important to be seen from a distance but also for an approaching boat to be able to determine your direction of travel. When boating at night remember the following: “When two lights you see ahead, turn your helm and show your red”. About Chris Outdoors, I’m in my element, especially in the water.

Placing them on the exterior side is helpful when I go fishing and indulging in other night activities in the water. Dalton Bourne on July 26, 2022 We love the lights! We put lights from Seaponer on my Jon boat right above the water line and use them for night fishing! The amount of brightness it offers is an assurance of my boat’s being seen clearly during the night. At the same time, the LED lights don’t consume too much energy, leading to a life span of up to 50,000 hours.  Leave a Reply Cancel reply Your email address will not be published.
