The new Leen 72 trimaran has about the same volume as a 100-foot monohull.

However, as Leen pushed into the powerboat market in 2021 with a 56, another happy trait of the tri-hulled design came into play—efficiency. By displacing the boat’s weight across three points of contact with the water—as opposed to one with a monohull, or two with a catamaran—drag is greatly reduced, because the hulls can be exceptionally narrow.

Its latest power offering is the Leen 72, which launched in 2022. True to design, the 72 is a very fuel-efficient boat. With a single 330-horsepower Cummins diesel engine, the boat has a range of 2,500 nautical miles at 10 knots, burning just a half gallon of fuel per hour. Additional electric drive units in the outboard hulls can assist with docking, or help push the boat along at 5 knots.

A trimaran design has, of course, another benefit beyond range and stability, and that’s the wide beam that makes its interior and exterior areas reminiscent of something that, in this case, might be found on a 100-foot monohull. The 72 is 29 feet wide, which translates to 1,378 square feet of useable space. 

The main deck is flush between the cockpit and the salon, making transit from the exterior to the interior seamless—a hallmark of thoughtful design. A comfortable, two-seat helm to starboard is accompanied by settees to port designed for guests curious about how a three-hulled boat is actually run.

The only glaring drawback to an unusually wide yacht like this Leen is that it might be challenging to maneuver it around a crowded marina. But when you balance the advantages of a triple hull, that may be a challenge some owners are willing to take on.

Catamaran vs Monohull in Rough Seas: Which is Better?

Catamarans and monohulls have different designs that affect how they handle rough sea conditions. In fact, they have an advantage over each other when sailing in heavy seas. Let's try to compare each type of vessel based on their performance, design, and stability, to help you decide which can give you a safer and more comfortable journey on the open water.

Regarding speed, efficiency, and stability, a catamaran may be the better option for you. Because they have twin hulls, they are more comfortable to sail in rough seas. A monohull can become more advantageous in rough seas when sailing upwind since it can point higher into the wind and can handle strong winds easily.

Catamarans with two rudders also allow for better control and maneuverability in rough seas compared to monohulls, which only have one rudder. Let's look at more of the comparison between these two types of boats when sailing through big waves in the sea.

  • When it comes to stability and comfort, catamarans can provide more stability. They are also less likely to cause seasickness and offer more living space and privacy.
  • In terms of speed, catamarans are also faster than monohulls because they have a smaller displacement. Their structure also makes them less likely to capsize or sink.
  • A monohull is advantageous when it comes to sailing upwind, and handling stronger winds. Their deep keel also provides them with increased stability and reduces drag, which can be an advantage in rough seas.

Catamarans Vs. Monohulls in Rough Seas

If you're planning to buy a boat, and you're deciding whether to go for a catamaran or a monohull, one of the many things you may need to consider is how they perform in rough seas. Rough seas can be challenging for any vessel, but some boats are better equipped to handle them than others. Below is a table summarizing how well these boats perform in rough seas:

A catamaran is a boat with two hulls connected by a deck. Because they have two hulls , catamarans are known for their speed, stability, and spaciousness. They are often used for cruising and chartering, as well as racing. They also have a wider beam than monohulls, which means they offer more living space and stability. They are less likely to heel or tilt to one side, are more buoyant, and have a shallow draft.

On the other hand, monohulls are the most common type of boat with only one hull. They are known for their simplicity, versatility, and affordability. Monohulls are often used for day sailing, racing, and cruising.

trimaran in rough seas

When it comes to rough seas, catamarans are generally more stable than monohulls in terms of roll stability. Monohulls, on the other hand, are better at handling heavy seas and high winds, but they can be more prone to rolling and pitching, and can significantly heel more than a catamaran.

If you are aiming for speed, efficiency, and stability, then a catamaran may be the better option for you. They are generally faster and more efficient due to their twin hulls, and their stability can make for a more comfortable ride in rough seas.

On the other hand, if you prioritize upwind sailing performance, sailing feels and responsiveness, and the traditional look and feel of a sailboat, then a monohull may be the better option for you. Monohulls sail closer to the wind and have a unique feel to them that some sailors prefer.

Detailed Comparison Between Catamaran And Monohull

trimaran in rough seas

Catamarans provide better stability and comfort

Catamarans are more stable, less likely to cause seasickness and offer more living space and privacy. Below is a table summarizing why catamaran is more advantageous in this category:

In terms of motion in rough seas

Catamarans are more stable in rough seas because they have two hulls instead of one. This means that they are less likely to roll or heel, which can make for a more comfortable ride. Monohulls, on the other hand, tend to pitch and roll more in rough seas.

In terms of handling seasickness

If you are prone to seasickness, a catamaran may be a better choice for you. The stability of a catamaran means that it is less likely to cause seasickness than a monohull. Additionally, the living space on a catamaran is often spread out between the two hulls, which can help to reduce the feeling of confinement that can contribute to seasickness.

In terms of living space and privacy

Catamarans also tend to offer more living space and privacy than monohulls. Because the living space is spread out between the two hulls, each hull can function as a separate living space. This can be especially beneficial if you are traveling with a group of people and want to have some privacy.

Both boat types have specific advantages in performance and speed

A catamaran is generally faster and more stable than a monohull, but a monohull can be easier to handle in certain conditions.

In terms of navigating upwind

When sailing upwind, a monohull has the advantage over a catamaran due to its ability to point higher into the wind. This means that a monohull can sail closer to the wind than a catamaran, which will need to tack more often. However, a catamaran can make up for this disadvantage with its speed. A catamaran can sail faster than a monohull , which can help it to cover more distance in less time.

In terms of handling strong winds

In strong winds, a catamaran is generally more stable than a monohull due to its wider beam. This means that a catamaran is less likely to heel over, making it more comfortable for passengers. However, a monohull can be easier to handle in strong winds due to its ability to reef the sails. By reducing the sail area, a monohull can reduce the amount of wind it catches, making it easier to control.

Catamarans and monohulls have different designs and function

Catamarans offer more deck and cabin space, shallow draft, and increased buoyancy, while monohulls have a deeper draft, reduced drag, and increased stability.

In terms of the deck and cabin space

One of the advantages of catamarans over monohulls is their wider beam, which provides more deck space. This means more room to move around and increased stability, which is important in rough seas.

trimaran in rough seas

Additionally, catamarans usually have two hulls, which means more cabin space and privacy for the crew and passengers. On the other hand, monohulls have a single hull, which means less deck and cabin space. However, monohulls usually have a deeper draft, which allows them to sail closer to the wind and tack more efficiently.

In terms of draft and buoyancy

Catamarans have a shallow draft, which means they can sail in shallow waters and anchor closer to shore. This makes them ideal for exploring shallow coves and bays. Also, catamarans have two hulls, which provide increased buoyancy and stability in rough seas.

Monohulls, on the other hand, have a deeper draft, which makes them less suitable for shallow waters. However, their deep keel provides increased stability and reduces drag , which can be an advantage in rough seas.

Both boat types have unique safety considerations

Safety is a top priority when sailing in rough seas. Catamarans are generally more stable and easier to control, while monohulls have a greater risk of capsizing but are also more maneuverable in certain situations.

In terms of the risk of capsizing

One of the biggest safety concerns when sailing in rough seas is the risk of capsizing. Catamarans have two hulls, which make them more stable than monohulls. This means that they are less likely to capsize in rough seas. Catamarans are also technically unsinkable , meaning that they will not sink even if one hull is damaged or flooded.

trimaran in rough seas

On the other hand, monohulls have a keel and ballast, which provide stability but also increase the risk of capsizing. If a monohull capsizes, it can be difficult to right the boat and prevent it from sinking.

In terms of navigational control

Catamarans have two rudders, which provide additional control and maneuverability in rough seas. This means that you can steer the boat more easily and avoid obstacles like rocks and other boats. Meanwhile, a monohull only has one rudder.

However, despite the number of rudders involved, the ability to control and maneuver the boat, whether a catamaran or a monohull, still depends on the design and construction of the boat, as well as the skill of the captain and crew in handling the boat.

Other practical considerations when choosing between catamaran and monohull

In terms of docking and anchorage.

Docking and anchorage can be easier with a catamaran due to the wider beam, which provides more stability. However, catamarans can be more difficult to maneuver in tight spaces due to their size. On the other hand, monohulls are generally easier to maneuver in tight spaces, but they may be less stable in rough seas.

For docking costs, catamarans tend to have higher docking rate costs due to their size and wider beam. Read this article to know more about the costs of docking a catamaran in different locations.

In terms of storage and equipment

Catamarans typically have more storage space than monohulls due to their wider beam and larger deck area. This means they can carry more gear and supplies, making them a good choice for longer voyages or liveaboard situations. They can accommodate larger equipment such as dinghies, kayaks, and paddleboards - making them a great choice for water sports enthusiasts who want to bring their gear along.

Monohulls, on the other hand, have less storage space due to their narrower beam and smaller deck area. This means they are better suited for shorter trips or day sailing, where less gear and supplies are needed. Monohulls may also be better suited for certain types of equipment, such as fishing gear or diving equipment, due to the layout of the boat.

In terms of crew accommodations

Catamarans tend to have more spacious accommodations than monohulls, which can be an advantage for longer trips or when traveling with a larger crew. However, monohulls may offer more privacy for individual crew members due to the separate cabins and tighter quarters.

Catamarans generally have more living space than monohulls so they can offer more room for sleeping, lounging, and cooking, which can be especially beneficial for larger crews or families. They also often have large, open salons and cockpits that allow for easy socializing and entertaining. This can be a great feature for crews who enjoy spending time together.

Monohulls, on the other hand, have less living space than catamarans due to their narrower beam. This means they may be better suited for smaller crews or shorter trips. They often have cabins located closer together, which can make it easier to communicate and work together as a crew, which is a plus for racing or cruising in crowded areas.

Choosing boat type based on personal preferences

In terms of aesthetics and personal taste.

One of the first things that come to mind when choosing between a catamaran and a monohull is aesthetics. Both types of boats have their unique look, and it is up to personal preference which one you find more appealing. Some people prefer the sleek and modern look of a catamaran, while others prefer the classic look of a monohull.

Another thing to consider is personal taste. If you are someone who prefers a more spacious and open boat, then a catamaran might be the right choice for you. On the other hand, if you prefer a more traditional sailing experience, then a monohull might be the better option.

In terms of suitability for families and couples

Basically, catamarans are known for their stability and spaciousness, making them a great choice for families with children or couples who want to have more space and privacy.

Monohulls, on the other hand, might not be as spacious as catamarans, but they offer a more traditional sailing experience. If you are a couple or a small family who wants to experience the thrill of sailing and doesn't mind being in close quarters, then a monohull might be the right choice for you.

Trimaran crew tells of dramatic rescue in rough seas after boat sinks

trimaran in rough seas

Crew members of a trimaran have described how they narrowly escaped with their lives following a dramatic rescue in rough seas off Bermuda.

The three crew members of Buddy , a 44-foot custom trimaran, had to abandon their boat to board a ten-foot inflatable dinghy in ten to 15-foot breaking waves 290 miles north-west of Bermuda.

The crew reported to Bermuda Maritime Operations that they believed their vessel had hit something in the sea before rapidly taking on water and breaking apart.

After contacting the US Coast Guard, they put out an emergency call to Vamoose , a J/133 sail boat that happened to be only 8.5 miles away from them and which came to their rescue.

A spokesman for Marops said: “I took a call from the US Coast Guard on December 4 at 8.10am. They were glad to report that there were three survivors from sailing vessel Buddy .

“The crew suspected that they hit something and reported that they were flooding with water. The boat took on a lot of water quickly and began to break apart.

“They had previously encountered Vamoose so they made a distress broadcast on VHF radio. The Vamoose was only 8.5 miles away. The crew of the Buddy evacuated into their rigid dinghy and Vamoose was soon on the scene, and recovered them from the dinghy.

“We had a photo of Buddy where it had one of the pontoons in the water and it was at a 45 degree angle with the pontoon in the water – it was a fair catastrophe.

“They got into Bermuda – one of our crew met the crew from Buddy and found them to be in good spirits considering. They are not in need of any further assistance from Bermuda Maritime Operations.

“We passed on the debrief to the US Coast Guard and they were thankful. They were glad that Vamoose was nearby and the whole thing ended well.”

The spokesman said Buddy was en route from Woods Hole, Massachusetts, to Puerto Rico when the incident occurred.

The owner of the trimaran said she had planned to retire on the boat with her husband – but would now have to start from scratch after its sinking.

Laura Shulman, said that she and her husband had spent two years outfitting Buddy and planned to spend the next ten years living on it while at sea.

She added: “Everyone was like ‘thank God, you got so lucky’, but then I think ‘did I get lucky or did I lose a boat?’”

Ms Shulman, from Massachusetts, said that she was on watch on Sunday night as Buddy sailed past Bermuda.

She said that the boat “suddenly came to a stop” around 3.30am and that she knew something was wrong.

“As soon as the boat stopped my co-captain, Ryan Finn, came whipping out of bed and we woke up our other crewmate, Tomasz.

“I said ‘Tomasz, get your life preserver on and cut the dinghy loose’.”

Ms Shulman said that they saw a four-foot long gash in the side of the hull, which quickly filled with water that acted as an anchor.

She reckoned that something sharp had torn open the boat but had no idea what.

Ms Shulman stressed that she and the rest of the crew were highly experienced sailors.

She said that Tomasz Dvorak, a close family friend, was “the best sailor a 23-year-old could be”.

She added that Ryan Finn, the ship’s captain, was a notable sailor who sailed from San Francisco to New York by himself over four months.

Ms Shulman said that she herself had been on the water since she was ten.

“I had a great crew – but it wasn’t that, there was just something out there floating that ripped open my hull.

“We were going like eight knots – not fast at all – the weather was fine.

“Something must have been just underneath the surface, we floated under it and it just sliced the hull open.”

Ms Shulman said that, despite the circumstances, she thought Bermuda was “great” and very accommodating.

“I stepped in here with no passport, so I had to go to the US Consulate the next day and get a passport.

“This island’s really well set up. I’ve never been here before – Bermuda’s a great place to get stranded.”

Ms Shulman said that she would visit Bermuda again under better circumstances. “I might even get shipwrecked out here again – I don’t think I could get here under worse circumstances.”

Ms Shulman, who is staying at the Grotto Bay Resort with her husband, who flew down after the incident, will be staying on island until Monday.

Willie Dresser, a crew member on the J/133 Vamoose , documented the experience in an article on www.sailingscuttlebutt.com .

He reported that the crew of the Buddy were Laura Shulman, Ryan Finn and Tomasz Dvorak.

Mr Finn wrote an account of the ordeal on Facebook . He said: “I was awakened at around 4am by something and came on deck to see what was happening. Boat speed had fallen to nearly zero and a quick look to leeward showed the ama [outrigger] underwater with only the deck visible.

“It was obvious that it had a big hole from a collision. Buddy began to slowly capsize over the next four hours …

“Our attempts to motor Buddy under her own power were useless as we could only make 1 knot at full throttle, and we had no steerage … after it was clear that we couldn't rescue the boat under its own power we decided to abandon ship and told Vamoose that we would like a rescue.”

As Vamoose approached, the Buddy crew managed to board their dinghy, taking with them a few essential items – passports, boat papers and some personal gear – in dry bags.

Mr Finn wrote: “Surprisingly, once drifting away, the ten-foot dinghy with three adults, 25 to 30 knots of wind and ten-foot waves, felt more secure than being on Buddy . Next thing we know the port bow of Vamoose was upon us and we boarded safely aft with all of our gear. The dinghy was left to drift away with Buddy .”

There was some difficulty boarding Vamoose but once conditions were safe they were able to board safely and with no life-threatening injuries.

Mr Finn said observers on land informed them that Buddy 's tracker stopped transmitting about an hour after it was abandoned, meaning it had probably capsized.

He added: “I don’t think any of us had regrets about our decision to abandon Buddy and live to sail another day. She was a beautiful trimaran though.“

Mr Dresser wrote in his report: “The conditions were 15-foot breakers with 53 knot gusts recorded and when we came around they were too close to the sinking sailboat so we had to loop around and wait for them to drift off around six or seven boat lengths.

“Once ready, we took them at the gate on the port side and rounded over to them, so they were on leeward not getting the spray.

“We threw them a line and pulled them into the break of the lifelines at midship where Geoff, Tim, and Chris pulled all three of the Buddy crew on board.”

They set a course for Bermuda and some 29 hours after the rescue they arrived “flying the biggest spinnaker we had” and setting a boat speed record of 19.3mph.

They eventually came in through Town Cut channel in St George’s, where they met customs staff.

Once on dry land the crew of Vamoose were treated to dinner by the crew of Buddy at The White Horse Tavern.

The crew of Vamoose we re due to set sail for Antigua yesterday.

“The technologies that made this rescue possible need to be noted here. Without them, we would have had to be rescued by the coastguard, in whatever capacity they chose, as opposed to sailing into Bermuda under spinnaker with some of our possessions and all of our bodies intact.

“At the helm station we had a tablet in a waterproof case. Using Navionics on the tablet, it showed Vamoose ’s position on AIS [Automatic Identification System]. The AIS transmission allowed them to sail directly to our position, not wasting a minute, and in light of the likely capsize, all those minutes counted.

“Without these technologies working so well, this could have been a much more complicated and potentially tragic story. If you ever wondered if they were worth getting for your next offshore passage, the answer is a resounding YES!“

galaxy-of-happiness-is-the-first-trimaran-superyacht-from-latitude-yachts

Galaxy of Happiness: The 53m trimaran taking yachting to another world

It is the kind of weather that would strand most pleasure yachts in port. Force 5 wind, white-capped seas and gloomy skies — a proper winter storm that makes the summer splendour of the Côte d’Azur seem a distant memory. Not an ideal day for a sea trial then — except, perhaps, for testing 53.3 metre Galaxy of Happiness , a futuristic trimaran specifically designed for stability in rough seas.

Gleaming in silver, Galaxy of Happiness sits alone in Monaco harbour looking like a spaceship ready for take-off. While her profile is inarguably eye-catching, the aim of this project is function over fashion. Efficiency, stability and speed are the ultimate goals.

She comes from the drawing board of Jean-Jacques Coste, of Coste Design & Partners , the multihull specialist known for its sailing catamarans such as 29 metre Cartouche . Galaxy of Happiness sits is its first foray into powered multihulls, but it is one that has been a long time coming.

Coste has been working on powered trimaran concepts for more than a decade, fully formed with naval architecture work-ups and tank testing. “We were simply waiting for the right owner to come along,” says Coste. “I’m a sail guy but that market is now only five per cent. And when you’re thinking about power and a bigger yacht, a trimaran makes more sense than a catamaran.”

The right owner did emerge at last, a Russian client in his 40s. “Creator” might be a more appropriate term as this client breathed life into both Galaxy of Happiness and her sistership, Galaxy , keeping the latter for himself in Greece and gifting Galaxy of Happiness to a friend.

The twin yachts were built alongside one another at Latitude Yachts in Latvia and delivered last summer. They mark the first full superyacht projects for this young shipyard that previously concentrated on smaller boats, superyacht refits and some subcontracting work for northern European yards.

Latitude specialises in composite but it has also set up facilities where it can build in aluminium. The yard’s youth was a virtue, it turned out. Freed from the shackles of heritage, Latitude wasn’t afraid to take on the wild and new.

Only a handful of yachts have been launched in Latvia over the years, so it was an interesting choice. But the owner had worked with the yard already, when Latitude built a luxury riverboat for him years before.

“It’s still Europe,” says Maxim Lyashenko, Latitude’s business development manager, “it’s not an exotic country. We work with a top French designer, top suppliers. Our workers are northern European, very hard workers who take pride in their work and love what they do.” The big difference, he confirms, is that the man-hour rates are very low, allowing Latitude to offer a competitive price.

Galaxy and Galaxy of Happiness don’t share a mould as they were built in unison in female moulds out of composites, carbon fibre, fibreglass, epoxy resin and polyurethane foam materials using Gurit’s Sprint infusion process. The entire boat is also post cured, for a light and strong structure.

“The owner was attracted to the unconventional but he understood the other benefits of trimarans as well,” says Coste. “Style is subjective but naval architecture and efficiency is a fact.”

Efficiency is one of the biggest benefits of a trimaran configuration, Coste says, as they require 40 to 50 per cent less energy than a monohull of the same length. There is less drag than a monohull, and Galaxy of Happiness is also hybrid-powered, outfitted with electric engines that can be driven by the generators or run through a battery pack to deliver a silent mode at a speed of six to eight knots for several hours.

This meets the owner’s brief for quiet running while fishing off his yacht, and it helps when manoeuvring in harbours. Galaxy of Happiness also benefits from a “wing tunnel effect” between the main hull and each outrigger — their positioning perfectly calculated to create several tonnes of lift at full speed, further reducing drag.

The naval architecture is arguably more complicated than a monohull as the interaction between the three hulls must be taken into account. The outriggers must be of precise length and in exact positions, something that Coste reviewed at length in air flow tests and with computational fluid dynamics.

Tank testing showed just how stable this hull form is, one of the benefits of a beamy trimaran. They are also fast, as proved by the speed records set by sailing trimarans. Galaxy of Happiness tops out at 30 knots, powered by her twin 2,600hp MTU diesel engines, which are supplemented with 120kW electric engines, coupled to retractable props in the outriggers.

These shafts and props fold in at high speeds, reducing drag (while the main engines in the main hull drive the boat). Not many yachts can go 30 knots and have a transatlantic range as well. “Even the navy is looking at these types of boats because they can go fast in rough seas and have low fuel consumption with a good range [2,300 nautical miles] at cruising speed,” says Coste.

The benefits of a trimaran are obvious, but what do you give up? Space, for one thing. The narrow hull form means less room for cabins. Galaxy of Happiness has the equivalent volume of a 35 metre motor yacht, but then again she’s also the price of a 35 metre.

But you can’t judge a trimaran by monohull standards. Instead of a huge upper deck, the main aft deck is the entertainment hub, with plentiful sofas, sunpads and a long dining table topped in tiger eye stone that seats 12. The petite sundeck, meanwhile, still has the expected superyacht spa pool and bar.

The saloon is surprisingly spacious, although styled simply by this owner, who eschewed Coste’s recommendation to add a bar in the corner. He just wanted a sofa, games table and big dining table, so this is what is found in the lofty room that is well lit by an opening skylight above. The windows and skylight are LCD glass, which is dimmable.

Two separate superyacht staircases lead to the cabins, which are split with the master and a guest cabin aft and another guest cabin amidships. One staircase is framed by a masterful piece of architecture in carbon fibre. The entire interior is warmed by the owner’s choice of red-tinted mahogany floors and cherry joinery, also stained in a red varnish.

The bold choice gives a colourful contrast to the cool exterior. Coste’s company did the GA and even designed the furniture, while the interior décor was created in-house by the yard.

The portholes in the cabins all open, so a fresh breeze can flow through the interior. You can open the doors and skylight to get a current of wind that replaces the air conditioning, even in summer. Coste says he carried this over from the sailing catamaran world.

Originally intended for private use, the layout can accommodate a big family and has guest cabins with three beds apiece. You could picture the rooms reimagined with a larger wardrobe or sitting area instead of one of the beds if this wasn’t to the taste of a potential new owner. The owner who received Galaxy of Happiness as a gift found in the end that he wanted even more berths and is on the hunt for a larger yacht.

Although catching the eye isn’t the aim, there is no denying that Coste and Latitude are trying to attract a new type of client, one who is younger and more concerned about the environment, adventure and speed than yachting traditions — or perhaps who has had little experience in yachting at all. Coste thinks the trimaran, with its blend of unusual styling and efficient, speedy performance, could be just the ticket.

Despite the modern lines, Coste says his inspiration for the twin trimarans comes from some of the oldest craft in the world. “It’s not that we’re actually doing something new — just look at Polynesian pirogues. Multihulls are one of the earliest configurations because they are efficient and stable,” says Coste. “It’s the same as those wooden craft: long, narrow hull and two outriggers.”

Perhaps the multihull has been forgotten and it’s time for a revival or, in Coste’s opinion, a yacht design revolution . He points to the bareboat charter market in the Caribbean, where sailing cats have overtaken the fleet thanks to their stability and comfort on board.

In 20 years’ time, Coste suggests, trimarans could take over the superyacht fleet, or at least put a dent in it, as more owners seek the combined benefits of fuel savings and speed. Multihull superyachts offer that rare combination of being eco-conscious while reaching their adventurous destinations more quickly.

“There is a place in the market for people looking for something that is both fast and efficient,” says David Legrand, of Fraser. “Perhaps it could appeal to the Mangusta owner, offering enough speed but not be prohibited by range.” He admits the multihull market is still a niche one, but for the younger millionaires who enjoy self-sufficiency it’s an appealing proposition.

It’s hard to ignore the elephant in the room — Galaxy of Happiness is reminiscent of Adastra , which similarly turned heads with her launch in 2012. Of course, there are plenty of white, multi-tiered yachts but with Galaxy of Happiness ’s space-craft exterior the resemblance is more striking.

According to Coste, this was never the intention. The creator/owner of the Galaxy vessels explored several styles before settling on this design, but in the end this met the brief of the owner more than Coste’s original ideas did. The owner specifically wanted a flowing, winged superstructure, without a flat windscreen and no reverse bow.

Staying under 300GT was also part of the aim, a challenge in a 53 metre. But even so, Coste is quick to point out the differences. “ Adastra is much more soft and curvy, we are more straight,” he says. “And we are much faster than Adastra ,” a fact that Coste attributes to the wing tunnel lift advantage.

It certainly proves true. Galaxy of Happiness is sure-footed in the choppy seas. Up on the flybridge there is some wetness, to be expected on a rough day, but noticeably far less rolling than a monohull. Inside the saloon, it is whisper quiet and so calm that you can’t tell we’ve hit a top speed of 29.5 knots.

It’s a boat that you feel comfortable going to sea in, and in conditions that would keep most monohulls in port. And best of all, you wouldn’t have to stodgily roll through the waves at an economical speed but could take off near top speed and get to safe harbour faster and in more comfort, although maybe not slip into every port.

This is just a sample of the possibilities of the trimaran platform. Coste shares the renderings for a number of other concepts that use other superstructures on the same hull form employed in the Galaxy twins. It is remarkable how different from Galaxy of Happiness they are and they display how a semi-custom platform could easily be born, offering a variety of exterior profiles and layouts.

One version has two decks with Portuguese bridge style windows reminiscent of a sailing catamaran wrapping all the way around — more of a floating loft than a spaceship. An 88 metre and 100 metre are also in development. A bold owner, other multihull projects ready and waiting and a yard willing to do things differently — for Coste, good things come in threes it seems.

Trimaran VS Catamaran – Which Boat Is Best?

trimaran in rough seas

If you’re planning to buy or charter a multihull boat, you might be wondering which one is better: trimaran or catamaran. Both have their pros and cons, and the decision ultimately depends on your needs and preferences. In this article, I’ll explain the differences between these two types of vessels to help you make the best choice for your needs.

Differences Between Trimarans and Catamarans?

If you’re in the market for a new vessel or plan a family vacation on the water, you might wonder what the differences are between a catamaran and a trimaran. 

Let’s see what they are:

A catamaran is a multihull vessel with two or twin hulls that are parallel to each other and fixed to a wide beam.

This design offers stability and speed, making it a popular choice for cruising long distances comfortably and even racing.

They also provide more interior space than trimarans, allowing for larger cabins and more storage.

When it comes to sailing performance, catamarans are known for their speed and agility.

Their twin hulls allow them to easily glide over the water, making them popular among boaters.

Cats are stable, fast, spacious, and super comfortable and are more stable at anchor than trimarans. However, catamarans tend to perform better in downwind conditions than in upwind conditions.

A trimaran is a multihull vessel that has three hulls. The two smaller outrigger hulls are attached to the center hull, which is larger and used for most of the boat’s functionality. 

This design offers even more stability than a catamaran, making it a great choice for those who want to sail in rough waters safely.

The three-hulled design makes them super stable, and as mentioned above, they can easily handle rough waters. They also have a smaller turning radius, making them easier to maneuver in tight spaces.

Another important thing to know about Trimarans is that they provide a decent degree of livability, but they fall short of catamarans in two regards. First, they heel more than cats, making it difficult to do things like cooking on board. Second, they support much less load than catamarans.

Pros and Cons of Catamarans and Trimarans

Before making a decision whether to sail a catamaran or a trimaran, there are pros and cons you must consider. Let’s see what there are:

  • Stability: Catamarans have two hulls, which makes them extremely stable. This means that you are less likely to experience seasickness or feel the boat rocking in rough waters.
  • Space: Catamarans have a lot of space both inside and outside the boat. This makes them great for large groups or families who want to spend time together without feeling cramped.
  • Speed: While not as fast as trimarans, catamarans are still faster than monohulls . They perform better in downwind conditions than trimarans and are great for long-distance cruising in calm waters.
  • Shallow Draft: Catamarans have a shallow draft, which allows them to enter shallow waters and anchor closer to shore.
  • Cost: Depending on how well the Catamaran is equipped, it can be more expensive than trimarans. Not always, though.
  • Harbor Cost: As catamarans have a very large beam, this means that a berth at the marina will be higher.
  • Navigation: Catamarans tend to struggle sailing close to the wind .
  • Speed:  Trimarans are known for being faster than cats and single-hull boats. They can easily reach high speeds and are great for racing or long-distance cruising.
  • Stability:  Trimarans are more stable than catamarans due to their three hulls. 
  • Space:  Trimarans are wide, but the interior is less spacious than catamarans.
  • Safety:  Provide exceptional buoyancy. If a trimaran capsizes, there is almost no chance it will sink.
  • Navigation: Trimarans can sail in any weather condition and perform much better upwind than cats.
  • Berthing:  Trimarans are more difficult to maneuver in harbors, making finding a berth in crowded marinas more challenging.
  • Maneuverability:  Trimarans require more ability from sailors to beach without difficulty than catamarans.
  • Loading:  Trimarans struggle to carry as much weight as catamarans.
  • Sailing: Trimarans require more effort and work on the deck.

Design and Structure

When it comes to design and structure, there are significant differences between trimarans and catamarans. Below, I’ll walk you through these two multi-hull vessels’ geometry, hydrodynamics, weight, and materials.

Geometry and Hydrodynamics

One of the most significant differences between trimarans and catamarans is their geometry. A trimaran has a central hull with two outriggers connected to a large beam, while a catamaran has two parallel hulls connected by a central platform.

This twin-hull design gives catamarans a unique sense of balance and stability. On the other hand, trimarans offer superior stability and adaptability in various water conditions thanks to their three-hulled design.

The central hull of a trimaran is typically longer and narrower than the hulls of a catamaran, which leads to better hydrodynamic performance.

Both trimarans and catamarans have different hydrodynamic resistance characteristics.

For instance, trimarans have less wetted surface area, which means they experience less drag as they move through the water. This feature makes trimarans faster than catamarans in rough weather conditions and high winds.

Performance and Speed

When it comes to performance and speed, there is a clear winner between trimarans and catamarans . Trimarans are known for their speed and are often faster than catamarans of the same size and weight. This is because of their unique design, which has speed and safety qualities that provide significant advantages over catamarans.

Trimarans have less hydrodynamic resistance than catamarans due to their narrower central hull, which allows them to slice through the water more efficiently in rough seas.

While catamarans are also fast, they often fall short of trimarans in terms of speed and performance. But that’s not always true in downwind conditions because cats are light, and their sails are positioned equivalent to the wind, making them faster than tris in downwind conditions.

Heeling and Capsizing

One of the biggest concerns when it comes to stability is heeling and capsizing. Heeling means the boat leans from one side to one side, while capsizing is when the boat flips over completely.

Both trimarans and catamarans heel, but trimarans provide greater stability and are less likely to capsize due to their three hulls. However, this doesn’t mean a trimaran can’t capsize.

In rough conditions, if a wave gets higher than half the size of the beam, the boat can flip over, but because trimarans have exceptional buoyancy, they float on the surface of the water and can serve as a rescue platform, but they won’t sink!

Comfort and Space

One important factor to consider when choosing between a cat and a tri is comfort and space. So, let’s look at these two types of boat’ accommodation: storage, cockpit, and living quarters.

Accommodation and Storage

One of the main advantages of catamarans over trimarans is the amount of space they offer. Catamarans typically have larger cabins and more storage space than trimarans. This makes them a great choice for longer trips, as you’ll have plenty of room to store all your gear and personal belongings.

Trimarans, on the other hand, have smaller cabins and less storage space. This can make the passengers feel a bit cramped, especially on longer trips. 

However, some trimarans do offer creative storage solutions, such as under-bunk storage compartments or overhead storage racks. Note that the latest models of trimarans are extremely spacious and offer as much comfort and space, if not more, than catamarans do.

Another difference between trimarans and catamarans is their weight. While trimarans can potentially be built lighter than some catamarans, catamarans are lighter on average due to having one fewer hull requiring structure and ballast.

The weight distribution of a trimaran is also different from a catamaran, with more weight concentrated in the central hull. This feature provides better stability and performance in rough seas and upwinds.

Catamarans, on the other hand, can support more load than trimarans. This feature makes them ideal for long-distance cruising and liveaboard lifestyles.

Frequently Asked Questions

Q: which has better resale value – trimarans or catamarans.

Resale values for both trimarans and catamarans can depend on factors such as the boat’s age, maintenance, and overall condition. Generally, catamarans have a larger market and may hold their value better due to higher demand, especially among cruisers and charter companies. However, a well-maintained trimaran can still attract buyers who value speed and performance.

Q: Which type of boat is more suitable for long-distance travel: trimaran or catamaran?

Both trimarans and catamarans are fantastic for long-distance travel. Still, catamarans are often preferred among sailors for extended cruising due to their larger living spaces and privacy on board. However, if speed is a critical factor for your journey, a trimaran might be a more attractive option.

Q: What factors should I consider when choosing between a trimaran and a catamaran?

When deciding between a trimaran and a catamaran, some key factors to consider include your intended use, performance expectations, available space, and budget. 

You should ask yourself:

  • What are your primary sailing goals – speed, comfort, cruising, or racing?
  • How much living and storage space do you need for your crew and equipment?
  • What kind of stability and performance characteristics do you value most?
  • Are you willing to compromise on space or speed for the sake of your preferred multihull design?

Final Words!

So, what’s the best boat? Well, both are great. The choice between a catamaran and a trimaran will depend on your needs and personal preferences. If you are looking for a peaceful trip at a slower pace with plenty of space for the whole group, a catamaran will be your best bet. On the other hand, if you want to zip through the water and get your blood pumping, a trimaran is what you need!

Hey, well I’m definitely the Catamaran girl. I love my space and don’t really need the thrill of the ride as much as I value the relaxation and holiday-type feeling. What’s your personal choice? Well since I’m more the sailor’s wife than the sailor, those other problems don’t really apply to me, do they? hahahaha what’s your personal choice?

We have something in common, because I am not a fan of racing . I love comfort and space, so I would go for a Cat!

Have a great day:)

I would go for the trimaran as it’s more stable in tough conditions as I would like to explore the world, not that I want to race. Catamaran is my go to option if I just want a nice vacation boat or something I agree that that one is better if you don’t want to race. I won’t buy a boat in the near future though, I certainly have not got the money, and I live at the wrong location, not far from the sea but still, I can’t even drive (no license). Great article though and I love boats. Wondered what the difference about these 2 are and now I know.?

Hi Stephanie, Sorry for the late reply. I had a minor technical issue:) Yes, trimarans are extremely stable and are faster than catamarans. However, those beautiful boats are quite expensive and if you plan on sailing around the world, you’ll need a small crew with you to handle the boat:). I am glad this article helped you know what’s the difference between a trimaran and a catamaran. Let me know if you need more info. I am always happy to help. Thank you for the comment and I wish you a lovely day.

This is a very informative comparison of the trimaran vs. catamaran style sailboat. They look similar on the exterior to the untrained eye – but it seems like the differences are pretty dramatic. If someone was looking to charter one for a vacation – do you have a specific experience or preference for one or the other?

It will depend on your personal preferences!

What are your needs? Can you be more precise?

I personally love to sail in comfort, I also need a lot of storage, so a cat is my favorite yacht!

Have a wonderful day:)

I have sailed ON a cat but never sailed one myself. Certainly a wonderful experience unlike a single-hulled vessel that rocks and rolls with the swells. That leads me to ask: if caught in rough weather (large swells and strong winds), how reliable is the trimaran? Does either configuration have limitations in this regard?

For the same size of boat, a trimaran have higher sailing performance ,a better ability to tack and go windward. So to answer to your question, a trimaran will handle better in strong winds and will go faster! But! Bear in mind that no matter if it’s a cat, trimaran, or monohull, the safety will all depend on when the sail will be shortened and how the boat will be handled in bad weather.

I hope it helped and if you have any other question , please feel free to get in touch:)

Have a great day!

Awesome write up on the differences between the two beauties. I have learned something new here. I am more of the adventure like person and your quick analysis of the Trimaran, tells me that I probably would lead to this option when choosing between the two.I will certainly browse around your site to check out other interesting articles you have on offer.Take Care, Roopesh.

Hi Roopesh,

Thank you for the compliment and you are very welcome to stroll around my website.

Take care too and wish you an awesome day!

It’s interesting to see the different opinions shown concerning of a debate. I don’t know about these vessels but I enjoyed reading it.

To me, I’ll go for Trimaran because of the modern interiors. I mean, it’s the modern feel that I’m looking for. That’s my main, personal factor.

Still, overall, I think it’s also suffice to say that these two cannot be compared because it’s not like with like. But that’s just my opinion. Trimaran for the win anyways!

So nice to see you again on my website:)

Yes, the trimaran Neel 45 has a modern look, but not every trimaran. Also, they are much faster than catamarans, sailors usually use them more for racing and catamarans for cruising.

Thank you for the comment, I really appreciate:)

I wish you a wonderful day!

I think now the Neel have brought out the 51 the game has changed somewhat. Lots more room ,walk around bed in master room. Lare shower in main head, the inside outside Cocloon as they now call it. Heaps of space below, fantastic headroom down below in central Hull. Much more classic looking boat on the exterior. Add the speed, stability and affordability compared to similar sized Cats and there really does not appear to be any more to be said. Of course it’s just my opinion and if money was not an option i think the Gunboat 60 would be the final choice, but for around 600k the Neel 51 has definitely set the standard. Take a look https://www.youtube.com/watch?v=1-997AEXfsk

Well, that’s a beautiful trimaran you have here, effectively, this one looks much more comfortable and wider than the Neel 45! I would definitely choose the 51 over the 45! I’ve really enjoyed watching the video, and it would be interesting to write an excellent review on the 51:). I agree with you, the Gunboat is such a beautiful cat, and now it makes it even harder to choose between the two of them:) Thank you for the comment and wish you a wonderful day!

Late arrival here but after reading and watching so many negative reviews about the Neel trimarans and the Neel 45 images of one build showing their train wreck quality, there is absolutely no way you can compare a Gunboat and a Neel. You’d be better off comparing it to the Yugo automobile.

The “Sailing Yacht Ruby Rose” did a recent video review of the newer Neel 47 posted on July 18, 2019 showing very clearly that its build quality is extremely lack luster. Although it was the Neel Trimaran that gave me the sea bug, one probably couldn’t purchase a poorer quality boat at any price. It’s an awesome concept but it’s a manufacturer no individual should consider buying from. I’m hoping one of the premium Cat builders will take on the task of providing a similar concept when I’m ready with my money.

Hello Eso, The beautiful thing in life is that everyone has different taste and opinion. I am glad to have you here and thank you for sharing your experience with the readers, this will certainly be useful to many people. I wish you a fantastic day!

Yes I’ve been looking at the Neel 51, Its turning my attention some what. It would make world cruising just that little bit faster and with room and comfort. PS I like the engine room.

Hi Mercury,

Thank you for the comment! The Neel 51 is a beautiful boat. She is more spacious and comfortable than the 45 Neel, but the 65 is even better! However, the 51 is an ideal cruising trimaran to sail in comfort. She provides everything sailors have ever dreamed of such as speed, stability, space, and luxury. What more to ask for:)

Thank you again for the comment and wish you a wonderful day!

I own a Catana 47 with one owner and two guest cabins. I and my wife want four cabin boat so that We can sail with our two daughters and their family including grand children. Should I buy Catana 53, Outremer 51 or Neel 51?

Thank you for commenting!

I am not a boat seller, but I will be more than happy to answer your question. The Catana 53, Neel 51, and Outremer 51 are fantastic boats. And to be honest, I would personally buy the Neel 51 because she is extremely spacious, lightweight and more stable than any catamaran out there.If you bring children, then you would want the boat to be safe. The other boats are also great but tend to perform less well in strong winds and heavy seas than the Neel 51. So yes, the Neel 51 is unbeatable in all categories! At least to me:)

I hope it helped and, please, feel free to contact me if you need to know further information. I am always happy to assist!

Thank you again for the comment and wish you a lovely day!

It’s really a good Information. I have never been in any one of the rides but I feel personally Cat is better. Do you guys know anything similar to this other then Cat trimaran like Semi-Submersible, drone etc. as I am doing a project that will help you to ride Cat Yourself alone!. Wish me good luck and please help me achieve my goal fastly, by sharing your precious knowledge and time. thank you in advance.

Hi Mohammed,

We would like to help you, but we didn’t really understand your question, could you be more specific, please?

Thank you for the comment!

Hello Daniella, Firstly thank you very much for your kind response. I would like to have some info about the Stability equation of Catamaran and different steering Mechanisms.

You are very welcome!

Managing heavy weather in a multihull

Multihulls World #167

Yes, bad weather! While cruising - and even during a race - almost everything is done to avoid it. Never pleasant to be caught out and/or damaged. Bad weather is anticipated in two ways: by avoiding being where it is likely to occur - sailing areas and times of year - and by preparing your multihull. A complete subject that we will be dealing with soon. But what to do when you are surprised by very strong winds and/or seas? Our 12 tips to stay operational and prevent the big three - Cold, Hunger and Fear - from taking over!

Create a notification for "Technical"

We will keep you posted on new articles on this subject.

  Suitable clothing

trimaran in rough seas

As long as the bad weather is manageable and the latitudes where you operate are mild in terms of temperatures, a traditional salopettes and jacket combination is perfect. But if the conditions become extreme, a survival suit will be essential.

Anticipate meals!

trimaran in rough seas

It’s very difficult to cook in severe weather. Prepare, if possible in advance, thermos of hot drinks, cereal bars and other dried fruits. Freeze-dried dishes are easy and quick to prepare; they allow you to eat hot food!

Keep the children safe

trimaran in rough seas

Children can stay in the cockpit as long as the seas are not too big. On condition that they’re wearing lifevests and harnesses.

Reef in time

trimaran in rough seas

Reducing the mainsail means positioning your multihull close-hauled or head to wind: easy when the sea is not too big, complicated with three-meter (10’) waves – even more-so at night. Take in a reef before you are caught out!

Furling the genoa

trimaran in rough seas

Reducing the genoa is possible at any speed. Remember to keep some tension on the sheet to prevent the sail and sheets from flogging too violently during the maneuver. The sailcloth, in this "half rolled" configuration, will suffer... It may be better to set a staysail on if you have a removable inner forestay, or simply to roll up the genoa completely.

Raise the daggerboards

trimaran in rough seas

The advantage of multihulls with daggerboards is that they can be raised all or part of the way in bad weather! The hulls can then slide more easily through the waves and make the helmsman's work easier.

Enough searoom?

trimaran in rough seas

The basic principle, in bad weather, is to move away from the area of strongest winds. Today, modern analysis of weather maps makes it possible to optimize its trajectory. But beware of the coasts: apart from some possible access in all weathers, many ports are inaccessible in very heavy seas. Allow yourself some searoom!

trimaran in rough seas

Reefed main, jib sheeted in on the opposite tack and helm hard over: this is the classic hove-to configuration. The multihull advances and drifts in relative comfort. A good formula to avoid losing too much headway and/or rest.

Lying a-hull

trimaran in rough seas

If the wind and sea become very strong, it may be wise to lie a-hull, i.e. stow the mainsail and furl the jib completely. Depending on the desired course, the support of one or more motors can be useful.

Trailing lines

trimaran in rough seas

Sometimes, extreme conditions may require you to trail lines - provided you have enough searoom. Your multihull, with no sail up, or almost (three reefs in the mainsail ideally), practically flies downwind and accompanies the waves. To remain safe, it’s sometimes desirable to limit the speed: a looped trailing line, preferably on reels, can be very effective, provided there are reinforced anchoring points.

Protect the nacelle

Par mer forte de l’arrière, les nacelles très ouvertes sur le cockpit – ou plutôt les baies vitrées – peuvent être soumises à rude épreuve. Des batardeaux sont conseillés. A ...

Safety trimaran

A trimaran is much more stable than a catamaran

The width of NEEL trimarans is an important factor for safety on the high seas because it is a guarantee of stability. 

On a catamaran the maximum righting moment occurs at 12° heeling, as shown on the stability curve. This angle can be reached relatively easily when sailing in strong winds and heavy seas.

However, on a trimaran , this maximum righting moment does not occur until 32° heeling, therefore in normal multihull conditions of use, this angle is never reached.

For this reason, and thanks to the centered weight distribution, a trimaran is much more stable than a catamaran. Weight being centered in the main hull’s technical compartment limits pitching and results in increased boat stability and therefore safety . This also enhances handling performance and comfort in big seas. On the other hand, catamarans have no choice but to distribute the weights (engines, batteries, generator, tanks) on the ends of their two hulls.

The PVC foam sandwich construction and collision bulkheads guarantee that the craft is unsinkable

The fin of the central hull protects the engine block and rudder gear. The shallow draft allows you to navigate close to the shore and enjoy the most beautiful anchorages. The high average speed optimises navigation planning, according to weather conditions. The fractional rig ( mainsail, solent, staysail ) facilitates short-handed operation, notably for duo crews. All embedded systems, such as refrigeration, electrical and electronic installations, energy generation and storage, fittings and rigging all benefit from our twenty seven years of experience in boat building.

NEEL trimarans are certified according to CE European standards by the French Institute for Nautical Certification and Standardisation (ICCN).

Safety 1

A trimaran offers better seakeeping:

Let’s consider both the trimaran and the catamaran heeling by 12°, which is the safety angle not to be exceeded on a catamaran. As shown in the graphics, the Righting moment (GZ) is much higher on the catamaran than on the trimaran. A high GZ means more brutal and uncomfortable seakeeping.

At this angle of heel the catamaran’s GZ is double that of the trimaran.

Therefore, sailing the trimaran is much smoother than sailing the catamaran.

The trimaran has less roll motion than the catamaran, as the center of buoyancy is never far downwind like on a catamaran. Again, centered weight is the key to success and comfort.

In fact, all significant heavy equipment is located in the main central hull on a trimaran whereas it is distributed half and half in each hull on a catamaran.

This superiority of the trimaran is even more significant in heavy seas as shown on the illustration here-below.

Catamaran vs Trimaran: Choosing the Perfect Multihull Vessel

26th mar 2023 by toi williams.

Rightboat logo

The debate over whether catamarans or trimarans are better boats has been going on for a long time without resolution, but the reason is understandable. The truth is that despite their many similarities, catamarans and trimarans have distinct characteristics that set them apart from each other, so each type of vessel offers a distinct boating experience. The catamaran vs. trimaran debate largely boils down to personal preference and how you intend to use the boat. Here are some of the things you need to consider when choosing between a catamaran and a trimaran. 

What Is a Catamaran?

A catamaran is a multi-hulled boat that has two twin hulls connected by a structure supported by a wide beam. Catamarans come in a wide variety of sizes, ranging from small rowing boats to large boats that are big enough to be used as car ferries. The structure connecting the two hulls can be anything from a simple frame with webbing to a superstructure that includes cabin and/or cargo space. Most of the recreational catamarans for sale are designed to hold two to 20 passengers.

What Is a Trimaran?

A trimaran is also a multi-hulled boat, but it has three hulls instead of two like the catamaran. The middle (main) hull is larger than the two small outer hulls attached to it. These hulls are connected by a lateral beam, wing, or some other form of superstructure, depending on the model. These types of boats also come in a wide variety of sizes, ranging from recreational yachts to ferries.

Advantages of Catamaran vs. Trimaran

The advantages of catamarans vs. trimarans are mainly based on comfort. Catamarans are spacious boats, known for their large living quarters with plenty of room on board for hosting gatherings and parties. Their popularity has enticed many boat builders to create increasingly luxurious designs on larger and larger boats. The catamaran also has a more classic style that appeals to those who want a boat with a simple, sleek shape. Catamarans are best suited for boating in calm seas, lagoons, and shallow waters.

Advantages of Trimaran vs. Catamaran

The advantages of trimarans vs. catamarans mainly come down to speed. Trimarans are among the speediest boats available, offering lightning-fast speeds on open waters. Many recent winners of notable boating competitions have been won by boaters piloting trimarans. These boats also perform well when heading upwind and are remarkably stable with their three-hulled design. The anchoring gear is installed on the main hull and is easy to deploy. 

Trimaran vs. Catamaran Speed

In the trimaran vs. catamaran speed debate, the trimaran is the clear winner. For long offshore races, trimarans have become the preferred vessels, and boaters piloting trimarans have won the Jules Verne Trophy in every race held since 2010. This is because of their unique design, which has speed and safety qualities that provide significant benefits for boaters. 

The trimaran's third hull makes the boat considerably faster than any other hull form due to the correlation between the boat’s waterline length and its speed. Having more hull distance in the water lets the boat reach higher speeds. Trimarans can also be pushed harder and are more forgiving than other boat styles in racing environments.

That doesn't mean that catamarans are slow. Some styles of catamarans are capable of breaking world records when the boating conditions are right. On downwind runs, a racing catamaran may be quicker than a trimaran, but for overall speed in various conditions, the trimaran comes out on top. 

Catamaran vs. Trimaran Performance

In the catamaran vs. trimaran performance debate, both sides have their advantages. A catamaran is easier to handle and maneuver with the boater having to handle the lines and halyards less often. However, this ease comes at the expense of speed, with cruising catamarans generally traveling slower than comparable trimarans. 

Trimarans are more versatile in their performance, and they perform better than a catamaran when traveling against the current or the wind. Trimarans can be used in nearly all weather conditions, are less vulnerable to drifting, and have less roll motion than a catamaran. However, handling a trimaran requires more work than handling a catamaran, which can be exhausting over long periods of sailing. 

Trimaran vs. Catamaran Efficiency

When comparing trimaran vs. catamaran efficiency, the differences are minimal. Multi-hulled boats are more fuel-efficient than comparable mono-hulled boats due to their hull forms and their lighter weights. Multi-hulled boats also tend to have smaller displacement and shallower drafts than other boat styles. 

The biggest difference in trimaran vs. catamaran efficiency is that catamarans nearly always have twin engines while trimarans generally run with one engine. A trimaran also has less hydrodynamic resistance than a catamaran because it spreads out the displacement across three hulls instead of two. This allows each hull to be narrower and more streamlined.

Catamaran vs. Trimaran Stability

The stability of multi-hulled boats is one of their biggest advantages over mono-hulled vessels. Multi-hulled boats benefit greatly from their wider stance on the water, and their wide beams and floats offer higher stability than a ballasted keel. Multi-hulled boats are also more buoyant because their floats help prevent immersion. When comparing catamaran vs. trimaran stability, the better boat will depend on the conditions on the water.

A catamaran's geometrically stabilized design reduces both heeling and wave-induced motion, providing a stable platform underway and at anchor. However, the catamaran's design is not as suitable for navigating heavy seas as the trimaran's build. The trimaran's three hulls provide excellent stability even in rough waves, but this can also make a trimaran less comfortable than a catamaran when the water is calm.

Catamaran vs. Trimaran Safety

Both catamarans and trimarans are considered to be safer on the water than mono-hulled boats. A catamaran has superior resilience and roll inertia that makes capsizing extremely unlikely. Its speed, steadiness, and ease of motion due to a lack of ballast also contribute to increased safety.

Trimarans are considered the safest multi-hulled boats because their three-hulled design makes them almost unsinkable. Many also have a core made of high buoyancy foam, helping them stay afloat even in the most brutal storms. Weight centering and a complete anti-drift scheme also make the boat safer for everyone aboard.

Trimaran vs. Catamaran Maintenance

Comparing trimaran vs. catamaran maintenance costs shows that many of the costs will be very similar for both types of boats. These costs include yearly boat service and repairs, annual haul-outs, and insurance coverage but exclude major upgrades. You will also have to budget for dockage, winterization, and storage for each year if you don't intend to use the boat year-round. 

Boaters are advised to budget between 5% and 10% of the boat's value for annual maintenance costs if their boat is less than five years old and a little more if the boat is older than that. Different maintenance jobs can be charged in different ways. Sometimes, the charges are based on the length of the boat while other charges are based on the number of hours worked.

Catamaran vs. Trimaran Cost

If you are looking for an affordable seafaring vessel, catamarans and trimaran are both good choices. There are many reasonably priced catamarans and trimarans suited for families as well as other models that provide more luxury for an additional cost. The materials that the manufacturer used to build the boat and the electronics included will also impact the price of the boat.

With so many different factors impacting the cost of different boats, you should choose the best vessel for you based on the features you want as well as your budget. Doing some research using the information on Rightboat's listings will help you find the right combination of quality and affordability you are looking for. Because we offer both new and used boats, nearly any boater will be able to find a boat in our listings that fits their needs. 

Choosing between a catamaran and a trimaran may seem simple at first, but the different sizes, styles, and amenities offered can make the choice much more complicated than you would think. If you prefer comfort and ample space while cruising, a catamaran may be the better choice. However, if you like speeding across the water and enjoy the thrill of racing, then a trimaran may be your best option.

Whichever boat you decide to purchase should fit your specific circumstances and requirements. Start the decision-making process by deciding what the primary use for your new boat will be. Will it be used more for family cruising or sport fishing? What bodies of water will you be boating in? Are you planning on staying close to shore or taking the boat into deeper waters? All these factors will impact whether you should choose a catamaran or a trimaran. 

With Rightboat's listings, you can learn about the features of the latest catamaran and trimaran models and see what you can expect to pay for the boats you are considering. You can sort through our listings by price, age of the boat, length of the boat, or listing date and then narrow down the results of a search using the rest of our filtering tools. If you are interested in buying a new or used catamaran or trimaran, take a look at our listings, and see what we have to offer today!

Catamaran sailing in rough weather

The sealed hulls of catamarans enable them to be sailed safely in very rough conditions. But as with other high performance craft, medium strength wind conditions are best for building up your experience as the catamaran is sailing at its optimum speed. Crews can learn how to handle the trapeze system when tacking and how to move quickly up and down the gunwale to the aftermost trapezing position.

However, only very experienced sailors should attempt to sail catamarans in strong winds and heavy seas. The two main points to bear in mind are to keep the boat moving as fast as possible when going to windward and to make sure the boat is balanced —keeping the hulls level by sheeting the sails well out and bearing away in gusts.

In rough weather, tacking should be kept to the minimum and should be carried out, if possible, in smaller waves wherever they appear. If you fail to get around on the tack, be prepared to reverse the rudders (see pages 124-5). Although you will often have to retract the centerboards on a reach to lessen the pressure on the sails, you must have the boards at least three-quarters down to tack. At all times, crew weight should be kept well aft except k

when urging the boat over the crest of a wave. Acceleration and deceleration will be very rapid so the crew must brace themselves securely using the foot loops or toe straps.

Spray or breaking waves can make visibility difficult, and some crews prefer to wear ski or swimming goggles to protect their eyes. Extra protective clothing will be necessary as the spray strikes hard enough to be painful.

The catamarans above and below are both sailing in rough weather on a reach-the helmsman and crew are well aft.

Rough Weather Catamaran Sailing

A number of smaller catamarans can usually be successfully righted by pushing the bows or sterns (it doesn't matter which) down into the water until they dip into the water sufficiently to allow the boat to become vertical. Once in that position, the boat can easily be pushed over into its normal attitude.

Power catamarans are gaining popularity in the cruising world thanks to their enhanced stability and ease of operation. They’re ideal for coastal cruising but can also be used for ocean crossing thanks to their stability and speed.

Here are some of the best power catamarans on the market:

  • Fountaine Pajot MY6
  • Nautitech 47 Power
  • Horizon PC74
  • Lagoon Seventy 8
  • ArrowCat 420
  • Sunreef Supreme 68

In this article, I’ll review some of the best power catamarans out there. I’ll also go over the main features of different power cats and if they can handle rough weather. 

But before we dive in, let’s get a better understanding of what power cats are.

Table of Contents

What Is a Power Cat?

A power catamaran (power cat) is a motor-powered boat that, unlike traditional boats, has two hulls connected by a bridge deck. These vessels are more stable than monohulls because of their wide base.  

Power cats also don’t have a leaded keel to weigh them down, so they’re pretty lightweight and fast. The lack of a keel also means that power cats are more suitable for shallow waters.

They feature large engines designed to handle their bigger bodies and weights, and serve different purposes, like fishing, cruising, or crossing rough seas. In addition, each hull has a separate engine which makes them more maneuverable, especially at turns and tight spaces.

Power catamarans don’t have sails or masts and get all of their power from the combustion engine (or electric motor), unlike their sailing cousins. In addition, these vehicles are much easier to steer because of their increased stability.

Power catamarans have more interior and exterior space thanks to their multihull design, making them perfect for cruising and liveaboard . They also have ample space for storing everything you need on a cruise without worrying about weighing it down. Catamarans offer increased privacy as well because each hull houses one sleeping area, separated by the living area between them.

Are Power Cats Good in Rough Water?

Power catamarans are good in rough waters particularly because of their multi-hull design. Their wide base makes them stable, and their high speed allows for outrunning bad weather.

Power cats that feature a high bridge clearance, will handle rough waters effortlessly. With the added height, you won’t experience pounding and slamming even in heavy waves, allowing the crew to easily control the vessel in challenging situations.

These boats are also faster than their sailing counterparts, which means they can get you out of rough waters quickly.

In addition, since catamarans are large and tall, maneuvering is easier because you have a better view of the surroundings. Additionally, you can steer from the interior cockpit (on certain models), making it easier to control the vessel in bad weather.

Finally, although a power cat doesn’t have a keel to help it right itself in case of capsizing, it will still float easily because of its positive buoyancy.

Are Power Catamarans More Efficient?

Power catamarans are more fuel-efficient than monohulls because they don’t have leaded keels. While keels are designed to offer stability by weighing down the vessel, they increase the wetted surface and thereby add drag.

Due to the catamarans’ narrow bow entry, there’s lower resistance, leading to smoother acceleration and greater fuel economy in catamarans. In addition, power cats show fewer spikes in fuel consumption in a single power band, especially because of their smooth acceleration and fuel consumption.

The figures reported by cat owners or manufacturers show that power cats have the best power-consumption-to-speed ratios.

That being said, you can improve fuel efficiency by maintaining lower speeds; studies have shown that speed can be the most important factor in fuel efficiency, regardless of the number of engines or hull types. 

Now that you have a better understanding of power catamarans, let’s take a look at the ten best models on the market.

1. Leopard 53

This 53ft (16.19m) power cat is the fourth generation of the widely popular Leopard catamarans, and brings with it all the great features from her predecessor, the 51. 

Although the 51 was the company’s best-selling cat, they added these features to the 53 along with new ones to repeat its success. For example, they have built an enormous saloon, flybridge, and galley by removing the foredeck cockpit in the 51 PC, making it 30 percent larger than the previous model.

This model comes with three or four stateroom layouts, with the 3-stateroom version featuring an owner’s stateroom, two sinks, a loveseat, and lots of storage space.

With two Yanmar 370 hp engines, a maximum speed of 22 knots, and a cruising speed of 17.5, you can enjoy a magnificent ride, whether it’s long-distance cruising or a fun night out with friends.

2. Fountaine Pajot MY6

This luxury power cat is 44ft (13.40m) long, making it super spacious and suitable for families and big parties. With its spacious flybridge, sunbathing lounge, and enormous galley, it’s nothing short of a second home on the water. 

You can steer the cat from the saloon or the 21sqm (68 sq ft) flybridge which features a sunbathing lounge, a pool, and a galley.

This motor yacht continues to delight with its luxurious combination of privacy and pleasure, with views of the sea in almost every interior space. With three cabins, two bathrooms, six cabin beds, ample storage, and a kitchen that opens into the cockpit, you can enjoy practicality and luxury in one place.

The MY6 is exceptionally seaworthy and stable thanks to its wave-piercing hulls and Volvo IPS engines.

Like all power cats, it has straightforward steering, enabling you to control this beast even in the roughest circumstances.

3. Nautitech 47 Power

Powered by dual Volvo Penta D4 engines, this model can output 225-300hp, reaching a maximum of 22 knots and a cruising speed of 18-20 knots . This 46′ 8″ (14.23m) long power cat comes in three or four cabin versions, depending on the customer’s preference.

No matter which layout you choose, you’ll get a spacious, luxurious, and comfortable catamaran with panoramic views from the cabin. The sleek, streamlined exterior design ensures elegant sailing and seaworthiness.

It’s easy for passengers to navigate the deck thanks to its seamless design that connects the saloon to the cockpit and the rear deck. The stern features a big swimming platform that can also accommodate a tender. The cockpit is usable in different weather conditions thanks to the clear covers wrapping the whole area.

This efficient catamaran promises long cruising for big families and groups with two 300L water tanks and a pair of 645L fuel tanks.  

4. Horizon PC74

The Horizon PC 74 is another luxury power cat that can give you the comfort of your home on water. This 73′ 9” (22.48m) long power cat with a 2,000gal (7570L) fuel tank is an enormous vessel that can accommodate more than 14 people.

The enormous hardtop on the three-piece windshield, the teak dining table, the U-shaped bar, the sun pad, and the swing-out stools all guarantee that you’ll have the luxury cruising experience of a lifetime.

This vast and wide catamaran allows you to access the aft deck from the flybridge via a curving staircase. The vast aft deck has a ten-person dining table, a wet bar, and storage space. You can separate the interior and exterior spaces through sliding glass doors and make the space appear bigger by opening them.

Reaching a top speed of 23 knots and a cruising speed of 19 knots, this enormous catamaran was built for efficiency and practicality.

5. Lagoon Seventy 8

This 78’1″ (23.80m) power cat with two 494 HP engines and a 2246gal (8500L) fuel capacity is one of the largest power cats on the market, offering both comfort and reliability. The enormous flybridge can feature a jacuzzi, a sunbathing area, a large foldable dining table, and a hardtop with a moveable roof. However, you can customize the flybridge based on your preferences.

The designers have compromised nothing in terms of elegance and high-quality materials with top-of-the-line finishes and interior paneling to create the kind of luxury you want.

The saloon is huge, well-ventilated, and separated from the exterior by glass doors and panoramic windows.

But what sets Lagoon Seventy 8 apart from other power cats, in addition to its enormous size, is the wide choice of layouts. You can choose between five different versions, all offering the same amount of storage space, living and sleeping area, and privacy.

Additionally, some versions are fully customizable, allowing you to pick every detail to your liking.

6. ArrowCat 420

This 41′ (12.73m) long express cruiser is a semi-custom catamaran with two-stateroom and three-stateroom layouts. The ArrowCat 420 is designed and built with comfort and strength in mind, and capable of handling rough waters safely.

The two Suzuki 350 hp engines give this model a maximum speed of 40 knots and a cruising speed of 20 knots.

The streamlined design and the angled hulls ensure the vessel cuts through the waves effortlessly, making it easy to maneuver.

The fully-equipped head features an electric toilet, a shower, sink, and mirrors, coupled with a dining table, floor storage locker, and teak-finished floors. This cat is built to combine luxury and comfort for both onshore and offshore cruising.

7. Bali 4.3

This 43′ (13.1m) power cat is made for ocean crossing in mind. With five different layouts featuring different combinations of cabins and heads, the company ensures you’ll get the kind of setup you want. Regardless of the layout, this cat offers a spacious master suite with a large double bed and other private sleeping quarters.

You can quickly add to the overall space by removing the adjustable glass doors to merge the cockpit with the saloon.

A feature that sets the 4.1 apart from its predecessor is the fixed aft deck between the hulls, which provides a passageway and eliminates the need to go from one hull to the other without entering the cockpit.

8. Sunreef Supreme 68

According to its designers, this model was built with a radical concept in mind while staying true to the company’s promise of building the most comfortable and spacious power cats in the world.

One of the greatest features of the Supreme 68 is its aft garage that houses a 5m (16 ft) tender and two jet skis in addition to other water toys.

You can also transform the aft to a large platform for water sports by lowering the garage door.

The four-stateroom layout features ample storage, ensuite guest cabins, queen-sized beds, and TVs to create a memorable stay. The white and beige furniture with chrome details and floor-to-ceiling glazing create a soothing atmosphere that blends with the practicality of the well-equipped galley. 

However, if you’re looking for something different, you can opt for a customized model from three different layouts.

9. Hudson 48

The sleek, diamond-cut design of this 46.46’ (14.16m) long power cat is usually the first thing to catch your eye.

It’s a light displacement cat that ensures fast cruising with a top speed of 24 knots and cruising speed of 8 knots thanks to the two 370hp Yanmar V8 engines.

The three-cabin layout features a master stateroom with a spacious and well-ventilated design made possible via the three overhead windows and opening deck hatches.

The saloon’s enormous helm station allows for comfortable and safe accommodation, making it great for rough waters and bad weather conditions.

This model also offers a few entertainment options with its large TV systems and mood lighting. The storage areas and the full-sized walk-in wardrobe give this model a comfortable, homely setting.

Here are Some of My Favorite Catamaran Cruising Resources

    Specifically, most cats are happy and safe sailing at 6-7 degrees of heel as measured in flat water, or on the trough of a wave. As the boat approaches 10 degrees of heel, the windward hull will be close to lifting. It is safe to say that a cat should not lift its weather hull while on a cruising passage!

  11. Managing heavy weather in a multihull

    Children can stay in the cockpit as long as the seas are not too big. On condition that they're wearing lifevests and harnesses. Reef in time. Reducing the mainsail means positioning your multihull close-hauled or head to wind: easy when the sea is not too big, complicated with three-meter (10') waves - even more-so at night.

  14. Catamarans for Rough Seas: What Makes Them Great

    Most cat enthusiasts believe a minimum of 40 feet (12m) is optimal for a cat to survive in rough seas. As a general rule of thumb, the best length-width proportion is 45 to 22 feet (13.72 to 6.71 meters). In addition to safety, a bigger boat will allow for more weight because it has more space, and you can arrange your gear in a more organized way.

  15. Catamarans In Rough Seas? Facts and Figures From Sailors!

    Rough seas are defined as waves that rise to heights between 2 to 6 feet (0.6 -1.8 meters). The hulls turn a catamaran into a floating platform that's pretty sturdy. In addition, their wide stance and solid construction make the vessel extremely stable, allowing it to withstand the water's constant pounding motion.

  16. Safety

    A trimaran is much more stable than a catamaran. The width of NEEL trimarans is an important factor for safety on the high seas because it is a guarantee of stability.. On a catamaran the maximum righting moment occurs at 12° heeling, as shown on the stability curve. This angle can be reached relatively easily when sailing in strong winds and heavy seas.

  18. Swath vs Trimaran: Deciding Between Similar Terms

    The swath/trimaran is a type of boat with two parallel hulls. The swath/trimaran is known for its stability and speed in rough seas. The swath/trimaran has a wider beam than traditional mono-hull boats. The swath/trimaran is often used for scientific research and ocean exploration. Answer Key:

  19. Catamaran vs Trimaran: Choosing the Perfect Multihull Vessel

    However, the catamaran's design is not as suitable for navigating heavy seas as the trimaran's build. The trimaran's three hulls provide excellent stability even in rough waves, but this can also make a trimaran less comfortable than a catamaran when the water is calm. Catamaran vs. Trimaran Safety

  20. Catamaran sailing in rough weather

    In rough weather, tacking should be kept to the minimum and should be carried out, if possible, in smaller waves wherever they appear. If you fail to get around on the tack, be prepared to reverse the rudders (see pages 124-5). Although you will often have to retract the centerboards on a reach to lessen the pressure on the sails, you must have ...
