Power Catamarans: A Complete Guide

Dec 06, 2023

less than a min

Power Catamarans, often termed as the epitome of modern maritime engineering, are gaining popularity for all the right reasons. Their distinct design, enhanced stability, and cruising efficiency set them apart from traditional monohull boats and even their sail-driven counterparts. This guide dives into the world of Power Catamarans, shedding light on their advantages and how they compare to other vessels like monohulls and trimarans.

Historical Prelude:

The concept of catamarans traces its roots back to ancient maritime cultures. However, the power catamaran is a relatively modern innovation that marries the traditional twin-hull design with powerful engines, offering a unique blend of speed, stability, and space.

Distinguishing Design:

Power Catamarans are characterized by their twin hulls, which significantly reduce the drag, thus enhancing speed and fuel efficiency. Unlike monohulls, they have a broader beam, which contributes to increased stability and more living space. The absence of a ballast for stability further lightens the vessel, contributing to its speed and fuel economy

Speed and Handling:

One of the significant advantages of power catamarans is their speed and handling. The twin hulls allow for a smoother glide over the water, making them particularly favorable for watersports enthusiasts. Their handling in rough waters is superior to monohulls, thanks to the inherent stability provided by the dual-hull design.

The stability of power catamarans is unparalleled, especially when compared to monohulls. The wide beam and twin hulls provide a stable platform, reducing the rocking and rolling common in monohulls. This stability is not only comforting in rough seas but also crucial when docking or anchoring.

Comfort and Space:

The spacious design of power catamarans offers homelike livability, with ample room for cabins, lounges, and even onboard amenities like grills and bars. The wide beam also allows for large deck spaces, ideal for sunbathing or enjoying the scenic ocean vistas.

Economy and Redundancy:

Power catamarans are economical, with fuel efficiency being one of their selling points. The redundancy built into their design, with separate engines for each hull, provides an added layer of safety, ensuring that the vessel can return to shore even if one engine fails.

Regular Upkeep and Care:

Power catamarans, given their unique design and structure, come with their own set of maintenance requirements. Like all boats, routine checks and upkeep are essential to ensure smooth sailing. The twin hull design means double the underwater gear – from propellers to rudders, which necessitates regular inspections for any signs of wear, tear, or fouling.

Antifouling:

Given that power catamarans have a larger surface area underwater due to their twin hulls, they may be more susceptible to marine growth. Regular antifouling treatments can help in keeping the hulls clean, ensuring optimal performance and fuel efficiency.

Engine Maintenance:

One distinct advantage of power catamarans is their dual-engine setup, but this also means double the engine maintenance. Regular oil changes, cooling system checks, and filter replacements are crucial. It's beneficial to synchronize maintenance schedules for both engines to ensure consistent performance.

The lifespan of a power catamaran largely depends on its build quality, materials used, and how well it's maintained. With proper care, a power catamaran can last for several decades. The engine's maintenance significantly impacts the catamaran's lifespan, with gasoline engines requiring maintenance at 1,200 to 1,800 hours and diesel engines at around 5,000 hours​​. The construction materials play a crucial role; for instance, fiberglass catamarans, when well-maintained, can last for many decades, while aluminum cats might change ownership after 10-15 years but can last a lifetime with proper care​.

World-Renowned Builders:

The power catamaran sector boasts several reputable manufacturers such as Lagoon, Leopard Catamarans, Fountaine Pajot, and other notable names like Seawind Catamarans​.

Lagoon, a revered name under the Beneteau Group umbrella, has carved its niche in crafting luxurious, spacious catamarans. A prime example is the Lagoon 630 Motor Yacht, embodying opulence with its nearly 250 sq. ft. aft deck and 900 sq. ft. interior, comfortably housing up to 12 guests. Known for its superyacht styling, it boasts superior fuel efficiency and a commendable average velocity-made-good of 9 knots.

Leopard Catamarans:

Emerging from the reputable Robertson and Caine shipyard in South Africa, Leopard Catamarans is synonymous with innovation and efficiency. The Leopard 53 Powercat is a testament to this legacy, showcasing excellent seakeeping abilities, offering 3 or 4 cabin configurations, and achieving a top speed of 25 knots.

Fountaine Pajot:

A trailblazer since 1976, Fountaine Pajot constantly redefines catamaran design. The Fountaine Pajot MY6 is a shining example, encapsulating the brand's visionary ethos. Stretching 15 meters, the MY6, equipped with dual engines of up to 2 x 353 Kw and 2 x 480 hp, promises dynamic sailing. Crafted meticulously by Pier Angelo Andreani, the interior mirrors a 20-meter monohull's spaciousness, reflecting modern aesthetics and comfort that stand as a benchmark in the Motor Yacht world.

These manufacturers continue to innovate, offering a blend of luxury, performance, and efficiency in their power catamaran models, making them a popular choice among maritime enthusiasts.

Comparing with Monohulls and Trimarans:

While monohulls are traditional and often cheaper, they lack the stability and space offered by power catamarans. On the other hand, trimarans, with three hulls, provide even more stability but at the cost of additional drag and less interior space.

TheBoatDB - Your Gateway to Maritime Exploration:

If you’re looking to delve deeper into the world of power catamarans and other vessels, TheBoatDB offers a comprehensive boat database. Explore various catamaran models, compare them with monohulls, trimarans, and other types of boats, and make an informed decision on your next maritime adventure.

In summary, power catamarans encapsulate a modern engineering marvel in the maritime domain. Their blend of speed, stability, comfort, and economy makes them an attractive option for a broad spectrum of boaters. Whether you are a long-distance cruiser, a water sport enthusiast, or someone who cherishes the tranquility of the sea, a power catamaran could be the vessel that transforms your maritime adventures into unforgettable experiences.

Dismantlable and transportable

A dismantlable powercat can be transported on a simple flatbed trailer... as long as it is of reasonable length and light in weight. Naval architect Richard Woods was able to test the validity of the concept with his own Skoota 28: the Aegean 30 is a development of the Skoota 28, still for building in plywood/epoxy and dismantlable. The objective was to increase the beam - now close to that of a sailing catamaran - and the headroom while offering two additional berths in the hulls. The outboard motors make beaching easier and safer - no rudders and engine legs. Two 40 to 60 HP engines guarantee a cruising speed of 10-12 knots (16-20 knots top speed).

Architect: Richard Woods Design  Material: Epoxy plywood Overall length: 30’2” (9.20m) Waterline length: 289’ (8.85 m) Beam: 16’5” (5.00 m) Draft: 14” (0.36 m) Headroom in nacelle: 6’3” (1.90 m) Light displacement: 5,500 lbs (2.5 t) Laden displacement: 7,000 lbs (3.2 t) Engines: 2 x 40 to 60 HP outboards  Cruising speed: 10/12 knots Max speed: 16/20 knots

L925 SEMI DISPLACEMENT POWER CAT

Amateur or professional construction in plywood/epoxy.

New Zealand-based naval architecture firm Dan Leech is offering a number of power multihulls from 25 to 60 feet (7.5 to 18 m) for amateur or professional construction. Among them, the L925 is the perfect choice for relaxed cruising for a couple. This model is built in ½” (12 mm) plywood - the panels can be digitally cut - with glass/epoxy reinforcements. Its limited beam will allow you access to a marina slip without any noticeable extra cost. On the other hand, the gain in habitability and stability is considerable compared to a single-hulled motorboat. This kind of construction is very accessible to an enlightened amateur (4,000 hours of work were counted for the first model) all the more so as having outboard motors for propulsion considerably simplifies the technical aspects. Despite its semi-displacement hulls, the L925 is capable of making more than 20 knots with two 90 hp engines.

Construction: Amateur or professional Architect: Dan Leech Naval Architect Length: 30’4” (9.25 m) Waterline length: 24’9” (7.55 m) Beam: 11’ (3.35 m) Draft: 19” (0.48 m) - engines up Recommended engines: 2 x 90 HP outboards Cruising speed: 17 knots Max speed: 22 knots Fuel: 79 US gal (300 l)

ARROWCAT 320

Compact but luxurious.

The ArrowCat 320 is a successful model - now in its third generation. The smallest of the Arrowcat range, it features a luxurious finish - rare in compact powercats - such as a wooden steering wheel, or modern, full instrumentation on a carbon-look dashboard. Inside, the manufacturer has paid particular attention to the owner’s cabin. The 320 is powered by two outboard motors. The limited beam of 10 feet (3.05 m) allows the boat to be transported by road in certain countries such as the United ...

Trimaran Performance vs Hull Form

QUESTION: If I build a multihull with straight sides of plywood to make construction easier, how much performance would I lose compared to a more ideal shape?

Now let's compare that to the shape with a semi-circular bottom that has the least wetted surface. Superimposed, the two might look like this (picture on right). Although I might refer to this simple shape as 'a Vee-hull', the shape I prefer actually has a little wider flat bottom in order to provide useful buoyancy lower down - see later. See also the article on relative virtues of flat panel shapes .

Right away, for the same displacement, one can see that the boxy hull has more draft, is narrower at the waterline but will have more underwater (wetted) surface. In practice, the Vee hull is likely to be 10% heavier in construction, but that might only mean say 5% required increase in overall displacement as the deadweight (crews, supplies etc.) could double the dry weight.

Now we need to look at how a boat's resistance varies with its speed and this is much related to its length. About 140 years ago, a William Froude discovered that up to a Speed/Length ratio (SLR)* of about 1, resistance is mostly made up of frictional resistance and in such a case, would be directly proportional to the wetted surface. From a SLR of 1 to about 2 (for a typical multihull), there's an increase in hull resistance due to waves made by the hull through the water, and the wetted surface resistance, although still there, takes a more minor role.

Once over a SLR of about 3.0, the wetted surface is again on the increase (although wave resistance is still significant).  So for different boat lengths, here are the speeds we are talking about.

*SLR = speed (in knots) divided by the square root of Waterline Length (ft)

So, below the speed given for SLR=1 and above the speed given for SLR=3.0, the majority of resistance would be directly affected by the roughly 20% increase in the wetted surface for the Vee (or 15% for the Box shape) and if we add in the 5% weight penalty, this could go to about 24%. ( While these percentages might also apply for speeds well under SLR of 0.5 or over 3.5, they would in fact be somewhat less than that at the SLRs listed, as not all the resistance would be due to surface friction )

But between the two values listed, wave resistance grows to a peak at around SLR=2 (for the average multihull) and at this point, the narrower beam of the Vee hulls could lower wave resistance enough to offset the frictional resistance and therefore be quite efficient in the range between the two speeds listed above for each length.   The box or Vee'd shape would also offer less leeway and that will also help to compensate.

If we widen the hull at the bottom, the sides can become more vertical and this more box-like section can further lower the wave-making compared to the Vee-section we started out with, as it disturbs the passing waves even less.

Of course, there are other aspects to consider too—like having less interior space at the waterline with the V-hull and also, that the V-hull would initially sink about 15% more for each 100 lbs of extra weight loaded on. The extra draft of a Vee hull is sometimes used as a longitudinal keel to resist lateral drift and that 'might' annul the need for a dagger board or centerboard, although deep fins are clearly more efficient for sailing upwind.

But if you're content to sail in the speed range indicated by the table, which is surprisingly broad, and can accept the other compromises, there's definitely a case for using the box hulls and keeping it simple. Outside of that, expect speeds at around 10% slower at the low end and similar at the much higher end beyond SLR of 3.5.

Of course, even 'ideal hulls' are seldom perfectly semi-circular and the total resistance also depends on many other things, such as the hull ends and even air resistance etc., but this gives a general idea of speed performance for such differing hull shapes, assuming all other factors are alike and comparable. On another aspect, the deeper V-hulls will also have more directional stability but in turn, be harder to tack—helpful for long trips but not for short tacking.

True V-hulls are seldom used for the center hull of a trimaran as they offer so little space. However, they have been used for easy-to-build catamarans and trimaran amas, for owners ready to accept the performance sacrifices noted above. However, the more box-hull can be justified for the sake of easy building. and at least offers more foot space than the narrow Vee'd for a main hull.   [Deep, near vertical flat-sided hulls are also drier than Vee'd hulls and have more recently proven to have less wave drag].

Recent tests (2009) on a small prototype trimaran with this Box-hull form and flat bottom, demonstrated that performance can be surprisingly good and some of what is lost through increased wetted surface is indeed made up by the slimmer form. While this may not be true at low speeds (below say 4 kt), the flat of bottom may give enough dynamic lift over at least part of the hull length to offset the theoretically greater surface, and show that the higher speeds of a light trimaran will not be as adversely affected by this box form as one might first think.

Editors Note: For this reason, this simple-to-build form was chosen for the new W17 that has since proven to perform very well indeed. The added resistance at the very low end (say under 4 k) will still be there and will need some imaginative boat trimming and added light-wind sail area to overcome. But for a significant speed range above that, this boat, especially when built to design weight, is proving that the flat underbody surface can indeed offer a very clean running hull with some dynamic lift at higher speeds that some W17 owners are calling 'oiling', as it reportedly feels 'like the boat is running on oil'. Even with the very moderate cruising rig, a speed of 14.9 k has already been recorded (by GPS) in this mode, so this is impressive and promises to offer lots of fun. So for this particular design at least, the high end restriction of a boxy hard chine hull has been overcome by the relatively narrow hull, the flat of bottom and its low-rocker design profile. Compared to a round bilge, the box-hull also offers additional lateral resistance, so the dagger board wetted surface can be slightly reduced for another small speed gain.

Then and now

The seafront of Cartagena in Colombia is the backdrop for two sailing vessels of different epochs and sharply contrasting character.

Against the sea wall  Galeon Bucanero , a replica of a Spanish galleon of the seventeenth century is totally at home against the fortifications of this historically significant Spanish port city.

In the foreground Chincogan 52  Sole currently circumnavigating the globe stops over en route to Panama and the Society Islands.

Over the years I've received many wonderful photos of our boats from around the world. This one is an absolute classic. Many thanks to Mike and Sarah Mason for the shot.

The design optimization of ship hull form based on hydrodynamics theory and simulation-based design (SBD) technologies generally considers ship performance and energy efficiency performance as the design objective, which plays an important role in smart design and manufacturing of green ship. An optimal design of sustainable energy system requires multidisciplinary tools to build ships with the least resistance and energy consumption. Through a systematic approach, this paper presents the research progress of energy-efficient design of ship hull forms based on intelligent optimization techniques. We discuss different methods involved in the optimization procedure, especially the latest developments of intelligent optimization algorithms and surrogate models. Moreover, current development trends and technical challenges of multidisciplinary design optimization and surrogate-assisted evolutionary algorithms for ship design are further analyzed. We explore the gaps and potential future directions, so as to pave the way toward the design of the next generation of more energy-efficient ship hull form.

Power Trimaran

Discussion in ' Boat Design ' started by BayouDude , Feb 22, 2005 .

BayouDude Junior Member

I am taking a course at the University of New Orleans and am going to design a power trimaran. I would like to do something about 80-100 foot with a 20-30ft beam, a range of 1000 miles and a cruising speed of 20kts. I was thinking the vessel would be used for a live aboard dive boat or possibly a yacht. I was intrigued by the trimaran hull and was wondering if anyone had any suggestions? Any input would be appreciated.  

fcfc Senior Member

You should look at Nigel Irens designs.  

D'ARTOIS Senior Member

What might be your motivation to choose for the power tri concept? Any mono would feed with ease your bill of requirements. The power tri, in its true concept, is just to achieve speeds normally unobtainable by monohulls. If you are looking for the wide-bodied designs you better go for the cat design. I play a bit around with tri-designs, actually winged monohulls, to go fast, stable and with a minimum of draft that allows you to enter shallow waters. Beachable too.  

doesitfloat Junior Member

I did some work a few years ago with a concerp of a tri Patrol boat. There was a large gain in deck work area however the seakeeping limited it's operation. If it's a fair weather fun boat probably work out just fine.  

Thanks for the input. I have just taken a look at some of Nigel Irens designs and they are impressive. I have decided on the trimaran because the class focuses on cats, tris and surface effect ships. Most of my experience is in tugs and offshore supply vessels so this high speed stuff is somewhat new. I would prefer to do something other than a monohull even though the benefits offered by a trimaran for this size and speed may not be exceptional.

boby boy owner of cla boat design

I believe a trimaran is a wonderfull choice, a multi hull boat was my first creation. just some advise fom a previouse design of mine: if you are gouing to have a center board instead of a fixed keel it is very conveniant to run it through a table below deck. this way it gives the table added suport and keeps it out of your way

From brian eiland's second link: http://www.naval-technology.com/projects/trimaran/ ADVANTAGES OF TRIMARAN DESIGN The advantages of a trimaran hullform over conventional mono-hulls are thought to be: reduced costs, reduced signature, significantly less drag increased speed, increased length, giving greater stability, and more room for the upper deck, which could be used for the flight deck as well as hangars for helicopters and extra armaments.

marshmat Senior Member

Radar signature depends very much on the shape and material of that hull. 90-degree angles are very good radar reflectors; stealth aircraft usually use a lot of 48-degree angles to minimize signature. Metals generally reflect more than composites. The shape of a boat is so complex that it's hard to predict radar signature without an actual test range. Having said that, if you suspect your vessel's radar signature is small (often the case with thin composite-hulled boats) it is prudent to hoist a reflector.

Reduced cost......could of meant "reduced operating cost". That is to say for faster speeds it consumes less fuel - I guess. 48-degree angles to minimize signature Click to expand...

Blue Moon 198'(60.35m) Feadship For Sale

Posted June 24, 2021 in Brokerage & New Build by Janine St.Denis

The 198-foot (60.35m) Feadship superyacht BLUE MOON is now listed for sale with Northrop & Johnson Yacht Brokers Kevin Merrigan and Wes Sanford. The yacht is listed for €43,900,000.

BLUE MOON is a truly remarkable superyacht. She was launched by Feadship in 2005, but has benefitted from constant and consistent upgrades, updates and care throughout her life courtesy of her adoring owner and her professional long-time crew. Some of her most recent modifications include a full superstructure repaint in 2018, the upgrade of her Quantum Zero Speed stabilizers to XT fin-type in 2019 and the repaint of her hull and main-deck bulwarks in 2021. The yacht’s interior and exterior both were designed by the renowned Donald Starkey. As such, BLUE MOON has won a variety of awards throughout her life, including “Best full-displacement motor yacht over 56 meters” at the 2006 ShowBoats Awards, among others.

In addition to providing the perfect on-water sanctuary for her owners, this pedigreed luxury motor yacht also has enjoyed a successful charter following. BLUE MOON’s exceptional features are certainly a draw. The yacht has a glass all-decks elevator, an observation lounge that provides sweeping views and a unique and flexible accommodations layout that can cater to almost any type of charter requirement. Furthermore, her on-deck master suite is expansive. At 1,200 square feet, it is no wonder this suite has space for a bedroom, his-and-hers en-suite bathroom, full owner’s office and a private gymnasium. The five additional staterooms, all with en-suite bathrooms, located on the lower deck can be converted to create a three-, four- or five-stateroom layout. This lower deck has an additional gym for guest use.

BLUE MOON features traditional interior styling with comfortable amenities that will delight guests. Various lounge spaces, bars, dining tables and entertainment options are found throughout the yacht. On deck, the yacht provides alfresco dining, a Jacuzzi, sunpads, a swim platform and so much more.

About Blue Moon

The owner's first Feadship experience was a two-week cruise on September Blue in the mid-1990s. An immediate convert, he soon bought the 47.50m Mi Gaea , which was renamed Blue Moon . Not long after, the designs for a brand-new Feadship were on the table and the second Blue Moon - at 50.28m the largest aluminium Feadship ever built at the time - was launched in 2000. The third Blue Moon was launched in 2005.

Launched in 2005, the 60.35 metre superyacht Blue Moon stands testament to meticulous design by Donald Starkey and expert construction by Feadship. Custom-built, this superyacht was refitted in 2008 and is ideal for sole-family use or perfect for long-journeys with charter guests.

With space on board for 12 guests, accommodation consists of a full-beam on-deck master suite, with office and guest room / gym, measuring approximately 1200 sq ft. The grand Owner’s suite is joined by two twin cabins connected to two queen cabins to offer a layout transformation from cabin to full suite. Her layout also provides space for 13 staff of highly skilled yacht crew and her Captain, making life on the water idyllic, down to the last detail.

Her glass cylinder elevator, large skylight in the sundeck, touch-and-go helicopter pad and updated 1972 Riva tender are just some of the design elements on board. This quintessential family boat benefits from the input of designer, builder and owner. Her interiors, also created by Donald Starkey, are a rich make-up of dark woods and light creams, expertly blended to create a stately home feel on the water.

Six people remain missing after UK tech tycoon Mike Lynch ’s superyacht sank during a freak weather event off the coast of Sicily. The British-flagged Bayesian was carrying 12 passengers and 10 crew when it capsized in the early hours of Monday morning after it was hit by a tornado over the ocean, known as a waterspout. One man, reported to be a Canadian-born chef named Ricardo Thomas, has been confirmed dead by Italian authorities. Six others – including Lynch, 59, his 18-year-old daughter Hannah – are still missing. Jonathan Bloomer, chairman of Morgan Stanley International, and his wife also remain unaccounted for as the search continues today with divers combing the wreckage. Follow Metro.co.uk’s live blog for latest updates on the Sicily yacht sinking Who is missing? Mike Lynch, an Irish-born software millionaire who founded tech company Autonomy in 1996, is one of four British passengers missing from the yacht. His 18-year-old daughter Hannah, who recently completed her A-levels, is also missing, along with Mr Bloomer and his wife Judy. Mr Bloomer was also previously chairman of the audit committee for Autonomy and testified for the defence in the high-profile court case over the company’s sale, which ended in June with Mr Lynch being found not guilty of fraud. Authorities say they are also searching for Chris Morvillo, a lawyer at the new York legal firm Clifford Chance, and his wife. Mr Morvillo represented Mr Lynch in the Autonomy case and celebrated the result in a social media post two months ago. He was also involved in the criminal investigation that resulted from the 9/11 terror attacks in 2001. So far, one body – thought to be the yacht’s chef – has been recovered, according to the Palermo Coastguard. Though it hasn’t been confirmed officially, a spokesperson for the Canadian foreign ministry told the BBC they were ‘aware of reports that a Canadian citizen has died’. Who has been rescued? Three crew members of the Bayesian have been named to be among those who were rescued. Leah Randall, from South Africa, was photographed leaving the coastguard headquarters yesterday, alongside Katja Chicken, her fellow crew member. Leo Eppel was also later named as the third surviving crew member. British national Charlotte Golunski was rescued after the Bayesian sank. She told Italian newspaper la Repubblica she held her one-year-old daughter Sofia above the waves to stop her from drowning. Ms Golunski said: ‘I held her afloat with all my strength, my arms stretched upwards to keep her from drowning. It was all dark. ‘In the water I couldn’t keep my eyes open. I screamed for help but all I could hear around me was the screams of others.’ Charlotte’s husband James Emslie was also pulled from the sea, with all three now being treated in hospital. Ayla Ronald, a lawyer working for Clifford Chance, was also rescued after the yacht sank, along with Irish national Sasha Murray and Mike Lynch’s wife, Angela Bacares. She is said to be anxiously awaiting news of her husband and daughter. Myin Htun Kyaw, a 39-year-old with a Burmese passport, was also among those rescued by the coast guard. Yacht captain Matthew Griffith, who is a French citizen, has also been accounted for along with 51-year-old James Calfield. Matthew Fletcher is another British national said to have been rescued, according to local media.
