Why these extreme multihull concepts could be the future of catamaran design

• October 13, 2020

Holiday homes, restaurants, even cities may soon be coming to a quiet beach or harbour near you, reports Sam Fortescue

The €500m beiderbeck-designed Galileo2 concept catamaran takes multihulls to another level and is capable of berthing yachts up to 80m

As boats become ever more like homes on water, something else is changing: designers and builders have been turning their attention to the market for floating buildings. New concepts to emerge range from a thatched beach cottage atop a catamaran hull to an entire floating city, generating its own food and power. The one thing they have in common is they’re movable structures that can be parked wherever they can drop the hook. And soon they could be coming to a peaceful estuary near you.

There is an opportunity here, of course, to create additional living and leisure space in areas where the land is already choked with people. Imagine being able to moor a temporary holiday village off Bournemouth Beach, for example, or create a restaurant off Dartmouth without affecting the townscape.

But the flip side of the coin is that someone could park a large floating structure right in front of your sea view, or occupy a quiet, sensitive environment. Imagine, as sailors, falling asleep in a deserted anchorage and waking up with a throbbing beach bar right next to us!

Floating homes and docks are being designed to use Seafloatech’s eco-friendly anchoring system

“If a craft is movable and can drop an anchor, it would be classed as ‘any other vessel’ and would not need consent,” confirms Martin Willis, executive officer of the UK Harbour Masters’ Association. “But if it’s a commercial business, it’d be subject to the relevant regulation – there are no rights to come in and open a business in a harbour without the Harbour Master’s consent.” Alternatively, it may fall under MCA coding as a passenger craft.

In some parts of the world, floating structures are already quite common. Upscale luxury holiday resorts in Thailand or the Maldives, for example, offer floating villas. And soon you might expect to see whole floating marinas if you find yourself close to St Tropez. France’s recent move to protect crucial Neptune grass meadows in the Mediterranean means that anchoring off the town is severely limited for yachts over 24m.

To get round the problem, a company called Seafloattech has developed a system of screwing steel frames to the seabed to moor big structures on giant hydraulic shock absorbers. “We had a prototype size in place for six months in the Bay of St Tropez,” says managing director Lionel Péan, the French ocean racing star and past winner of the Whitbread Round the World Race . “It could accommodate up to 70 boats in a maximum wind of 42 knots, with up to 2.4m wave heights with no structural problems or injuries.”

Offshore developments

The hydraulics keep the marina on station despite the tide and help to counteract wave action. It is even possible to use the system to tether a boat or a home through storm-force conditions, insists Pean. “If you want to build something to resist a typhoon, for instance, you have to make special arrangements with the customer. It can be done, but it costs a lot. In the Med, you don’t need 5-6m waves resistance.”

Seafloattech itself will ultimately just licence the tethering system, but it is working with partners who envisage all manner of structures atop their platforms. There are swimming pools, beach clubs, superyacht berths, hotels and villas.

“We believe that the demographic surge will force the coastal states to really focus on offshore coastline development,” adds Pean. “I am for a two-fold operation including sanctuary areas and social offshore development zones. We think that Northern Europe will take some more time but as soon as we have some units up and running, it will happen quickly.”

Seafloattech has developed a steel tethering structure that is screwed to the seabed with hydraulic shock absorbers that can secure any number of floating homes. Standard versions can cope easily with Mediterranean weather conditions

Another French concern, Faréa, has taken a markedly different approach, developing a home that sits on two deep metal floats that also contain cabins. It is a simple catamaran, propelled by an outboard at the ‘stern’ and anchored with normal ground tackle at the ‘bow’. Navigation is slow and only for fine weather, but retractable centreboards mean it can be beached.

“They amount to 86m2 of space, with seven double cabins separate heads and bathroom and three terraces,” explains founder Christophe Roi. “They are self-sufficient in water and electricity, thanks to the oversized photovoltaic panels and fuel cells.”

A thatched roof multihull?

The original plan was for something more like a floating house, but feedback from insurers pushed Faréa towards a craft that meets category C of the Recreational Craft Directive. “It means they can stand up to Force 6 and 2m waves,” explains Roi. “What with rental prices so terribly high in England, I am certain that living on water should be a possibility.”

Original Faréa concept was for an economical floating home with a thatched roof, but later versions can meet RCD Cat C

A fully equipped F2C model would cost around €160,000 to install, he adds. With the average Newquay home costing £730,000, according to RightMove, he has a good point.

Alva Yachts offers more architecturally ambitious 45m2 holiday homes with an infinity pool and a terrace. Not self-propelled, costs range from €85,000 to €200,000 depending on finish. The fledgling German company is using its founders’ experience of building catamarans that run on renewable power to offer low-carbon homes.

“The floating homes are literally super luxury yachts without propulsion,” explains co-founder Mathias May. “The hull and ‘sails’ are made of composites, while energy consumption, supply and distribution is comparable to a solar yacht. We strive to be as efficient as possible to get rid of diesel gensets in remote areas. It is no coincidence that our first customer for such a project comes from the Maldives.”

This ocean resort features a number of Alva Yachts floating eco holiday homes costing from €85,000 to €200,000

Meanwhile, two Finnish companies have developed a series of even larger floating structures whose near-total self-sufficiency allows them to remain offshore indefinitely. Architects Sigge and builder AdMares have turned the world’s largest floating villa (all 6,000m2 of it) in Abu Dhabi into an autonomous boat capable of tackling waves up to 1.2m.

By fitting a wheelhouse and three Rolls Royce US 55 FP azimuth thrusters with a total 750kW output, the villa can move itself around the sheltered waters of the emirate. An anchoring system at each end of the platform is equipped with whopping 38mm chain and 1,575kg anchors.

Off nearby Qatar, the Finnish firms have been hard at work installing 16 floating hotels with a total of 1,616 rooms, aimed at providing temporary accommodation for the huge influx of football fans due for the 2022 World Cup. With four storeys including a lounging area and a restaurant, each hotel can simply be towed to a new location after the tournament. The only restriction is the 4m draught.

This Oceanix concept sees hexagonal clusters of floating homes linking up to become towns with net zero emissions

Floating towns

Several orders of magnitude further up the scale and you reach floating towns. Some concepts, like Oceanix, are very serious attempts to expand the boundaries of human habitation to ‘the next frontier’. It is a consortium of companies focusing on the UN’s ‘New Urban Agenda’ with a plan to build homes on pods clustered in hexagons, in turn clustered into larger hexagons, and so on, up to cities of 10,000 people.

Their vision includes parks, arenas, restaurants, offices up to three stories high and built-in docking for solar-powered watercraft. Energy is harvested from waves, wind, sun as well as algae bioreactors and more to create a net-zero consumer, while food is grown on and under the city.

“We believe humanity can live in harmony with life below water – it is not a question of one versus the other,” says CEO Marc Collins Chen. “The technology exists for us to live on water, while nature continues to thrive under. Floating cities by design embrace all types of marine activities, so they are complementary to existing activities like fishing and sailing.”

Nomadia is a multi-deck craft for 3,000 guests. An alternative to cruise ship holidays, it features an internal marina and even beaches

The initial sites envisaged for a city are all on the fringes of the Tropics, from Japan to Thailand, and the structures are designed to withstand Category 5 storms.

A more Eurocentric view comes from two designers of cities on boats. French naval architect Sylvain Viau has developed an outline for a triangular craft measuring 372m in length, with a jaw-dropping beam of 369m. Across 12 decks moving at up to 5 knots, some 3,000 guests can be accommodated, along with lecture halls, meeting rooms, restaurants, shops, manmade beaches and an internal marina capable of berthing ten 100ft yachts.

Fun and games afloat

These giant ‘craft’ are nothing to do with loving the sea or even respecting the enivronment. “People are not interested in the sea, they are interested in casinos, cinema, fun entertainment,” Chen explains. “In my imagination, you welcome everybody on board in a nice location. The platform doesn’t move during the season, only in the winter, when it’s time to find a new spot.”

With yards promoting designs such as this BlackCat 50m, superyacht multihulls look set to be the next very big thing

At anchor, giant inlets like gills down each flank would channel waves into a generator to produce energy. And when it’s time to move, the boat raises its 300-tonne anchor and blows out its ballast tanks to reduce its draught from 20m to 11m.

Germany’s beiderbeck designs recently made headlines with the publication of a €500m concept catamaran called Galileo2, capable of berthing yachts up to 80m, and offering a fold-down restaurant and an open-air amphitheatre cinema. With a nod at managing greenhouse gas emissions, this small floating town would be powered by gigantic fuel cells, and would pioneer so-called marine thermal energy in yachting.

“You can use the temperature difference between the deeper and surface water,” explains Timo Hartmüller of beiderbeck. “Obviously, you need to be in deep water, but we designed the yacht to stow a 1km long hose on board.”

Some of these floating titans may never make it off the drawing board, particularly in view of the way that coronavirus has decimated the cruise ship industry. But the current is running hard towards extending communities above the waves, and whatever you may think of these concepts, be they luxury pads or modest holiday cabins, expect to see more of them coming to a stretch of coast near you.

Mobile pontoon

Multimarine near Plymouth is nearing completion of a 108ft x 28ft motorised platform called the Gweek Pontoon, which the owner plans to charter out for use as a mobile regatta and watersports base.

It is fitted with an anchor and windlass, as well as three 200hp engines, and includes a built-in hydraulic slipway. It is built from foam-core vinylester laminate and carbon fibre for light weight and a trifling draught of just 100mm.

9m Steel Catamaran; thoughts?

Discussion in ' Boat Design ' started by rustybarge , May 20, 2016 .

rustybarge Cheetah 25' Powercat.

Hi All, Can steel make a good materials choice for a small 30' Cat for home building, , and what plus/minus points does 3mm plating pose? http://www.bodenboatplans.com/popup_image.php?pID=23&image=0 http://www.bodenboatplans.com/popup_image.php?pID=23&image=1 BB260 "Steel Catamaran 9 Metre" $595.00 Length 9.0 m Displacement 6500-7500 kg Material Steel Hull Draft 0.85 m LWL 7.9 m Hull Weight 4500 kg steel Beam 3.8 m Max Speed 12 kn Motor capacity 2 x 60 hp Fuel Type Diesel Fuel Capacity 700 litres 100mm x 50 x 3mm cross beams folded plate Fabricated frames 3mm flanged plate. 30 x 3 mm stringers. 2.5 mm superstructure . . A 9 metre steel power catamaran for long distance economical cruising. The alternative way of spacious live a board cruising under power. Also available in aluminium construction and a 4 stroke outboard version in steel or aluminium. An exceptional design. There is nothing else like this seagoing cat on the internet Steel, or steel extended version , also aluminium construction with extended cabin and flybridge Single chine catamaran Hull tunnel to waterline is 300mm loaded and 370mm light Propeller dia 400mm. Fresh water 200 litres. Sewage tank 60 litres. Intended for living aboard for extended periods in the Med. where provisions are available on a weekly basis. This craft was designed so that all nominated fitting out items including tanks etc. were available from the Vertus catalogue, which is readily available world wide. Accommodation is two double berths forward, galley and dinette in wheelhouse saloon. The cockpit is relatively large and is ideal for relaxing outdoors. The shower/toilet space is unusual in that the toiler is located at a lower level on one side and the shower on the starboard side. There is internal entry to each of the machinery spaces with larger maintenance hatched in the cockpit. Sub division with bulkheads make this a very safe boat. The engines shown in the plan are 60hp Dutz as shown in the Vertus catalogue At first we thought that a 9 metre steel catamaran would not be practical. A preliminary design established that providing it was built in 3mm plate,with fabricated frames and tunnel beams,a satisfactory design was possible. The hulls are deep to carry the additional weight and the craft is designed to run at displacement speed with initial estimates indicating a top speed of 14 knots and a very economical cruising speed of 10 knots. Particular attention has been given to the machinery installation with the hull aft designed to accommodate the propellers, reduce draught and enable the catamaran to sit on the bottom. The original craft was designed in 2002 for use cruising the Greek islands. The advantage of steel is that the craft can be built in the open and shot blasted and epoxy painted on completion of the steel fabrication. Click to expand...

Let's see.... The design displacement is roughly four times what a 30' cat should weigh, and the speed is pretty marginal. Setting aside the difficulty in welding steel this thin, you would be far better buying a 30' fiberglass sailing catamaran and adding bigger engines. It would be pretty inefficient compared to a designed power cat, but still far better than this.... Thing.

Actually no difficulty welding this steel thickness with a wire feed machine. Stick welding would be difficult for me, but I am no professional welder. With a quality MIG machine even I could weld very well for a thin steel hull. Cutting the steel with an abrasive wheel is also easy, with virtually no distortion. Steel weight for 3mm thickness is about the same as 35mm plywood, whereas in plywood you could use 20mm thickness. So the hull plating in steel is considerably heavier than with plywood, but most of us know that already. Steel hulls, with a good coating system, can hold up very well, and if that is your preference, then proceed to get what you want.

I doubt if you will get 14 knots with twin 60hp on a 7.5T catamaran. Has someone achieved that speed with one? I recall you have posted before about the powercat you were building. So I am pretty sure you know my Skoota 28, which is, as Stumble says, nearly a quarter the weight of the steel boat. The hulls are 6mm, the decks 9 and 12mm. Yet has proven to be a successful live aboard cruiser. My Skoota 32 is currently being built and will be under 3T in the water If you think that a steel boat will be cheaper remember to add in the cost of bigger engines and the running costs. I suspect the bridgedeck will slam as heavy boats need higher clearance The 9m Catalac doesn't weigh 7T! Richard Woods of Woods Designs www.sailingcatamarans.com

rustybarge said: ↑ My project is to home build a small coastal cruising cat on a small budget. The advantage of steel is easy welding; alloy needs an experienced expert . The materials for a 30' plywood cat come to about $20k using good quality marine ply. Here in Europe steel is at an all time low of £300/ton because of Chinese dumping and oversupply from European mills. I estimate £2k would cover the material costs in steel. Click to expand...

waikikin said: ↑ Rustybarge, Steel wins as a low cost start to fabricate, the other materials soon catch up when you factor in abrasive blasting and paint system....welding consumables/gas/ abrasive discs are a minor add on but add up, then you need to build the interior which generally means lining the habitable areas which in effect is building a thin ply/laminate boat inside much of the steel one. It would be one tough little cat, one was for give away incomplete in Wollongong a few years back. At the other end of the project you would have a tough, comfy, slow piece of paradise..... on resale which you may not care about could be very low. Cecil E was a respected designer of commercial craft and some pleasure craft. If he was designing today in the market available that boat might be very different than presented. I'd never say don't build it but keep your eyes wide open at the big pic. Al the best from Jeff. Click to expand...

SamSam said: ↑ It's in your moniker rustybarge...rust. In thin steel, a corrosive pit is halfway through the skin. The worst is from the inside out, from condensation. I imagine creating and maintaining a protective coating in all the nooks and crannies inside those narrow, deep hulls would be a chore. Click to expand...

rustybarge said: ↑ This problem had occurred to me, especially if there are parts of the frames with doublers . how do you stop corrosion once its got into two thin steel plates spot welded together? I suppose after good layer of two pack paint, some sort of wax treatment like waxoil could be injected into overlapping sections of the steel work. But is plywood any better if it gets wet and starts rotting, and how would you dry it out in narrow hard to get at sections? Click to expand...

whitepointer23 Previous Member

what about alloy glued instead of welding. i read somewhere that alloy boats can be glued together just like plywood. i think the bond is also a lot stronger than glued ply bonds. even a combination of epoxy and rivets like an aircraft.

waikikin said: ↑ Well you need to seal weld the perimeter, I'm assuming you're indicating the gussets? lapping the framing. The "secret" with steel or timber for that matter is ventilation and limbering(drainage holes), an effective paint scheme is very important to steel, access to or elimination of void areas as well. The 3K structurally complete cat is fantasy if including coatings even in Pound$. A plywood or composite cabin may be ok if the landing/upstand/coaming is in staino, the fastenings required generally compromise coatings to steel & eventual results blow up with oxygen mixing with steel Jeff.

The ZEN50 is a game changer. World’s first series production catamaran equipped with a wingsail, it defines a new distinctive class of its own, where genuine zero-emission meets high comfort and performance, limitlessly. 

Designed from scratch for ZEN Yachts by award-winning naval architect Julien Mélot , this full carbon catamaran is the ultimate essence of technology driven, high performance and luxurious, eco-friendly leisure yachting. 

The blue water capable ZEN50 lightweight racing carbon hulls are combined with a huge solar roof for an unrivaled solar power vs. displacement ratio above 1:1 (18 kW / 17 tonnes), making this yacht completely energy self-sufficient. A revolutionary, fully automated, wingsail - by Ayro© - can be added as a range and speed extender. The yacht’s high capacity battery bank powers a powerful silent electric propulsion, allowing the ZEN50 to achieve 14 knots and maintain high continuous speeds in unrivaled safety and comfort, indefinitely… 

The ZEN50 is offered with or without wingsail and comes in 3 main different versions: Racer, Cruiser and Explorer, each dedicated to a different usage and owner profile. We use these versions as a basis to define a final, bespoke specification for each of our valued clients and ZEN Community Members. Scroll down for more details, specifications and prices.

1st WINGSAIL series production yacht in the world!

The OceanWings32 - by Ayro© - was initially developed for Team Oracle, for the America’s Cup 2010 in Valencia. Over years, it has further been developed and automated by VPLP and was installed on Energy Observer in 2019. Two years of field feedback have allowed the Ayro team to fine tune the algorithm commanding the wingsail. The ZEN50 is the first series production leisure craft to be equipped with this fully automated wingsail. It is controlled at the touch of a finger on screens, is automatically adjusted and has several safety modes and features. The two parts of the wingsail can be hoisted and lowered independently and with the simple touch of a button. The wingsail OceanWings32 is the ideal complement for the solar roof for those wishing to cruise long distances off-shore with zero-emissions.

Greatest ratio SOLAR POWER / weight on the market

At 17 tonnes lightweight and 18,000 W of peak solar power, the ratio of the ZEN50 is at over 1 kW per displaced tonne of water or beyond 1:1 which is far beyond any other blue water CE Cat A yacht in this size range. Lots of solar power for little water to displace is the strong and healthy foundation the energy self-sufficient ZEN50 is built upon.

Performance CARBON sandwich hulls

The hulls of the ZEN50 have been designed from a blank screen for ultimate efficiency - understand minimum drag or minimal energy consumption for a range of speeds from 6 to 10 knots. Their shape is aggressive, sharp and slender. Their reverse bows cut through water like a sword cuts through butter and their curvature is reminiscent of graceful dolphin bodies. These hulls are undoubtedly of the performance type and are built with the best available composites: Carbon fibre and Corecell™. The combination of high strength, low weight and performance design allow the ZEN50 to reach speeds of up to 14 knots.

INFINITE range at high CONTINUOUS speeds

With maximized solar and wind power and minimized energy consumption… the ZEN50 can sail continuously at speeds varying between 6 and 10 knots. Thorough simulations in various sea states and weather system have consistently shown the ZEN50 will be able to achieve performance catamaran speeds continuously without using a genset. With the ZEN50, the world is your oyster and the wildest destinations are within your reach with this self-reliant vessel!

True ZERO-EMISSION operation

The first ZEN50 unit, whose construction started in March 2023, will not be equipped with a genset at all and will not have any fossil fuels onboard. The ZEN50 energy system with its very large capacity 160 kWh battery bank, has been designed to function for days in complete safety with minimal solar energy harvest and no wind. It is perfectly safe with no backup genset and operates 24/7 without any polluting emissions.

NO FUEL , no costs

Naturally, requiring no fuel to operate day in day out is great news for the environment, it is also fantastic news when sailing into remote areas where fuel bunkering might be near impossible or where the fuel quality might be an issue. Finally, it also makes a massive difference in this yacht’s costs of operation. Imagine the hundreds of liters of diesel saved over just a week, the obsolete engine maintenance schedules, the clogged filters and dirty tanks from another age… Welcome to a new burden-free, energy self-sufficient era, welcome to clean and graceful eco-yachting, welcome to ZEN Yachts.

Highest SAFETY & reliability

At ZEN Yachts, we have made some design choices to attain energy self-reliance with the ZEN50 that reduces the habitable volume in the hulls, similar to performance catamarans. Where we have not and will never compromise is on safety. Our main voltage system is 48V making it perfectly safe to work on. The level of redundancy of the batteries and solar panels is 10! The main electrical architecture is split in 2 so that should anything happen on 1 hull, the entire vessel can still operate normally. There are 2 independent helm stations and the ZEN50 is packed with special safety features, nonsubmersible compartments and we can even offer an in-depth practical course on safety equipment usage and management. Sailing with the ZEN50 is not only exhilarating and clean, it is ultra safe!

Unrivaled space & COMFORT

The ZEN50 offers the speeds of a performance catamaran, the comfort of a large motor yacht and the simplicity of an electric car. No less than 2 large day beds, 3 dining areas for over 10 people, 1 professional galley and 2 wet kitchens, 5 heads, up to 4 double ensuite cabins, 1 bunk double and 1 single together with both saloon and dining areas converting into extra sleeping areas, this is simply unrivaled on a 50 ft. catamaran. Add an electric tender, dive compressor, satellite internet, 2 helm stations (cockpit and flybridge), a solar roof that converts into a gigantic upper deck to enjoy the most epic sunrises and sunsets, welcome onboard the ZEN50!

Catamarans are quickly outstripping single-hull boats for long-distance journeys. They are more stable and comfortable , and some can travel more than 200 miles in a day. In today’s article, I have put together a complete (well almost) list of some of the best catamarans for circumnavigating the planet; the question is, which one is best for you?

The best catamarans for sailing around the world include: 

• The Fountaine Pajot Ipanema 58

These cats focus on speed, safety, and comfort for longer journeys. 

This article will show you the seventeen best catamarans for long journeys, and why they’re the best. You’ll also learn some great tips on what to look for in a Catamaran and how to save money by buying a used catamaran. Let this list be a jumping-off point for your future research!

Pro-tip; here are the actual costs of maintaining a cat and here are considerations on how to circumnavigate .

The Best Catamarans for Sailing Around the World 

A catamaran is a double-hulled boat with a deck or cabin area in between (bluewater cat definition in this article ). The double hull design means that the boat rocks less, sits higher on the water, uses less fuel to sail, and can be sailed in shallower waters than a single-hulled boat without worrying about grounding. 

Catamarans come in a variety of sizes and can be sail-powered or motor-powered and range from single-person sailing boats to family-sized yachts. Every catamaran design is different, and the twin-hull shape offers many ways to customize the layout of a ship. 

Each boat on this list is a larger catamaran (+40ft, more on size here ), so if you’re going to sail around the world, you want lots of space for provisions and rest.

Of course, there are tons of technical specs for each of these boats, but I’m going to focus on the overall features of each of these catamarans, what makes them stand out, and why they would each be an excellent choice for a transatlantic journey. 

Antares 44i 

The Antares 44i is an excellent option for sailing around the world and was explicitly designed for long-distance cruising. It performs well in any weather conditions, can be sailed easily by two people, and you’ll be able to sail long distances and live in comfort. 

Although it can be easily sailed by a crew of two I believe that a true bluewater cat should be set up for single-handed sailing, more on that in another article .

This catamaran features a stateroom on each hull and a forward cabin with plenty of storage space. The living and entertainment features include a flatscreen tv and a high-end deck speaker system. 

With this model, Antares dedicates itself to high-quality boats with optimal rigging and engine configurations. 

Atlantic 42

Atlantic is no longer building this catamaran, but there are usually a few pre-owned boats on the market. You can also get it made custom if you love the design, but be prepared to spend more money on a custom boat (custom boat also gets custom problems ;)). 

The Atlantic 42 is slightly smaller than some of the other catamarans on this list but is a seaworthy vessel. 42 ft is what most sailors I interview ( in this article ) said was the smallest cat to safely cross big oceans. It is also a decent size to counter the risk of capsizing (more on that here ).

It has a forward cockpit and pilothouse, which gives the owner a better use of space and makes the boat easier to navigate. With single-handed capability, one person can sail it easily and let the rest of the crew relax. 

One of the best-praised aspects of the Atlantic 42 is its galley, more extensive than most 42-footers (12.8-meter) can offer. 

One of the few 50 footers (15.24 meters) that can be sailed by just one person (many would of course disagree on this).

The Catana 50 is a catamaran worthy of an overseas journey. Its size adds to its stability on the open waters and its ability to sail straight through the choppy ocean and windy conditions. 

The Catana is also incredibly spacious on the inside, with substantial cabins and showers. The biggest downside to the Catana 50 is its price, as it’s much more expensive than most of its competitors. 

Catana also holds up well against some of the fastest cruising cats out there, here’s a list of the fastest cruisers if you are interested in that.

However, if you can find a gently-used Catana 50, you can rest assured that this boat will last! 

The Dolphin 42 is unique because of the use of daggerboards instead of fixed keels. This upgrade means that the boat has some pretty decent upwind performance while at the same time being faster downwind.

Centerboards and daggerboards offer some interesting downsides compared to mini keels. This is an interesting discussion and I suggest you read another one of my articles if you want to deepen your knowledge a little.

These catamarans are some of the lightest on the market. Not many Dolphins were made, so they are relatively hard to find. However, if you want a small, lightweight boat capable of going great distances, the Dolphin 42 is an excellent choice. 

Fountaine Pajot Belize 43

The Fountaine Pajot Belize is another well-built cruising yacht. Its core is made of foam instead of balsa, which reduces the risk of structural damage due to a rotten core in case of water intrusion. 

The design of Belize offers many options for customizability, with large open spaces and a combined saloon, navigation, and dinette area. 

There are two styles of Belize catamarans for sleeping quarters. You can either purchase a boat with an entire primary suite on one hull or one with two cabins in each hull. The first option is great if you are sailing the world alone and not expecting many guests, as it increases the storage capacity. 

Understanding what factors to consider when getting a cat can be hard, there are just so many of them (such as the daggerboard discussion above), I have tried to compile some of the most important in this article .

The boat also has wraparound windows to increase the sense of space in the galley. 

Fountaine Pajot Lucia 40

Fountaine Pajot is one of the best sailboat manufacturers existing today, as their boats are well made and highly versatile. The Lucia 40 is no exception – it’s a smaller boat but has a lot of room for moving around and on-board living. 

The living area is remarkably spacious on this catamaran for its size. 

The galley and lounge easily accommodate 6+people. The Lucia 40 doesn’t disappoint when it comes to sailing either, as the narrow hulls slice through choppy waters with ease. 

Most catamarans today are built to withstand rough weather but that doesn’t matter as much if the crew isn’t up for the task, I firmly believe that the most important thing a boat should consist of, is knowledge. Therefore taking online courses ( two free here ) or reading books ( my favorites here ) is imperative.

Gemini 105M

Gemini’s boats have been on the market for years and are solidly built for cruising. This boat is one of the most popular ever made, I personally would consider something different for offshore cruising, but since it has such a good reputation, I felt I had to add it to the list.

If you want to understand why I am hesitant to take this boat around the world, I recommend you read my article: What are trampolines on a catamaran?

The Gunboat 62 is a great catamaran and set the standards for the rest of the impressive Gunboat lineup. It’s sleek and spacious while being robust and capable of transatlantic journeys. You can easily travel the world in a Gunboat 62 with several people and not feel cramped. 

The yacht was made for speed and power and remains one of the fastest catamarans on the market, even rivaling the newer Gunboat models.  GABO

Although the earlier models of the Gunboat 62 weren’t designed for a lot of cargo, you can still find space for everything you need without compromise. 

Lagoon catamarans are known for their reliability and ease of use. If you are considering a catamaran for the first time and are unsure about the technicalities of sailing, a Lagoon boat is a great option. 

The Lagoon 380 is probably the smallest cruiser on this list, which makes it better suited for solo or couple sailing.  

When I go looking to buy something, whether it be a boat, campervan, or whatever, I create a checklist and classify all the things I want either by NEED or NICE to have.

I believe the Lagoon 380 to be sub-optimal for my NEEDS, even though it does check a lot of NICE boxes, there’s a step-by-step article on the NEED and NICE method here .

There are several cabin options available on the Lagoon 380, but if you’re sailing by yourself, you can settle for three cabins and a larger galley and living space. With a smaller cockpit and broader side decks, the Lagoon 380 packs a lot of practicality and ease of sailing into a more compact catamaran. 

If you like the idea of a Lagoon boat but want a little more space, the Lagoon 42 is the upgraded version of the Lagoon 380. With all of the same benefits, it comes with more space for cabins or storage, making it one of the best-selling Lagoons of all time. 

The Lagoon 42 is also a faster cruiser built for strength. While it’s not the fastest on the market, it works well in choppy waters and windy conditions, making it great for the beginning sailor to go on a more extended trip. 

Many people have completed an around-the-world sail with this ship.

Although there is a flybridge version, I would recommend the “open” version due to several factors, some including increased windage and a higher boom. More on flybridges pros and cons here .

For stability, safety, and durability, you can’t beat the Lagoon 42. 

The Leopard 45 performs better with less storage weight because of the relatively low bridge deck clearance. If the boat is fully loaded, you could experience some wave pounding. However, the cockpit is open and airy, with devices that block the sun and provide maximum comfort while sailing. 

The Leopard 45 is an incredibly beautiful boat,   and has a strong reputation for excellent build quality!

Leopard catamarans are one of my personal favorites, as such I have written an entire article about the brand, so if you want to understand its pros and cons then here is the link . Gabo

Designed in South Africa, it features a high rear arch for extra support and very smoothly connected decks. The galley is large and open, and most Leopards offer a four-cabin plan. If you are traveling with another person, this boat is an excellent option for you! 

The Manta 42 is another classic catamaran that you can buy used (at a decent price), as it is an incredibly seaworthy vessel. While still in production, the Manta was one of the most popular catamarans on the market. 

It is still in high demand amongst circumnavigators. Buying a used Manta 42 usually means that you inherit some of the previous owner’s boat upgrades! 

The Manta 42 also made it to my list of the 9 safest catamarans on the market ( link ).

This blue water cat can be sailed by one or two people, making it ideal for liveaboard couples or long-distance shorthanded sailing. The galley is in the saloon ( instead of in one of the hulls ), making the cabins below more spacious and better equipped. 

Overall, the Manta is well equipped for sailing around the world. 

Nautitech 44

Nautitech is an excellent brand of the catamaran, with several different designs per boat. The Nautitech 44 has a unique feature, you can have it with two options for steering: twin wheels or a single wheel.

The Nautitech 44 also features a cockpit on the same level as the saloon. The door between the two is more convenient than a hatch and dramatically reduces the risk of water damage during rain pour. 

This is also the same boat that aeroyacht president Gregor owns, he has offered some great insights into Nautitech in the book Catamarans (amazon link )

Outremer 45

Outremer is famous for being one of the fastest brands of catamarans on the market. If you need speed, the Outremer 45 might be the perfect choice for you. It has a top speed of 16 knots, which is higher than almost every other catamaran of its class. 

While the Outremer 45 is known for speed, it doesn’t compromise on the quality of living. 

You can settle into life on this boat with complete peace of mind. Even as a beginning sailor, the steering is simple and easy to use, and the autopilot is top of the line, so you’ll be able to sail across the ocean in an Outremer without issue. 

Privilege Serie 5

A French-designed catamaran, the Privilege Serie 5 is one of the most comfortable 50-foot (15 m) yachts available. The unique cabin layout includes the master cabin in the boat’s center instead of in one of the hulls. 

The Privilege Serie 5 is also incredibly easy to sail, despite its larger size. 

The sails and controls lead to the helm, where the raised deck makes it easy to see all around the deck. If you want to cross the ocean with a full crew then the Privilege Serie 5 might be perfect for you! 

Seawind 1000

The Seawind 1000 is the smallest boat on this list, measuring 33 feet (10 meters) long altogether. However, this doesn’t mean that it’s not livable. If you are sailing on your own or with a partner, there is more than enough space to live in the Seawind 1000, which includes the option of a centered cabin or two hull cabins. 

Because it’s small, the Seawind 1000 is easy to handle. The mast and sails are all manufactured for extra stability and ease of use. 

Overall, the Seawind 1000 is an excellent example of a simple, safe, and seaworthy catamaran. 

Note: since this is a small catamaran it will also be more sensitive to heavy weather so trip-planning becomes even more important.

The Voyage 44 is one of the oldest cats on this list, having had its hay-day in the mid-1990s. However, this also means that a used Voyage 44 will be cheaper than a newer boat. If you can find a Voyage with previous responsible owners, you will inherit any upgrades and fixes that they’ve made on top of a very seaworthy boat. 

The Voyage 44 has more storage and space than most cruisers of its size and is known for behaving very well in choppy waters. 

This catamaran does its job well while providing adequate space for cooking, sleeping, and living aboard. 

What To Look For in a Long-Distance Cruising Catamaran

If you are planning to sail around the world, you need to be very careful about which kind of catamaran you decide to use. Many of the things you want in a boat really comes down to personal preference, so be sure you know what design preferences you want before you start shopping! 

Size and Payload

The most important thing to consider when buying a catamaran is how much space and cargo you need because the larger the boats are, the bigger the payload it can handle. Decide how long you want the ship to be and how much you’re taking with you. 

It’s vital not to overload a catamaran, this will reduce performance and increase risk of unwanted behavior in heavy seas.

Cabin Placement  

Most catamarans have options for a “Maestro” cabin placement, where one entire hull is the master suite, and the other cabins are located on the opposite hull.

Cockpit and Protection From The Weather

Is the cockpit on the boat you’re looking at covered or open? This can make a difference on the high seas, especially during rainy weather. 

The size of the ship also can affect how many people you need as a crew. If you’re traveling by yourself or with one other person, you don’t want to buy a boat that needs a larger crew. 

Buying Used? 

If you don’t want to spend the money on a brand new catamaran, I don’t blame you. Several of the ships on this list are out of production and can only be found used. However, for circumnavigation, you do want a boat of high quality to keep you safe and dry until you make it to your destination.  

When buying a suitably used catamaran, it’s essential to look at the refit history of the boat more than the year it was made. Catamarans are sturdy, and the general design has been the same for at least the past decade. 

If you find a newer, larger, cheaper boat, you should look into its history. 

Your best bet to save money while buying a catamaran will be to buy an older, probably smaller boat with an excellent refit history and no serious issues. It will still be an investment, and a sturdy used catamaran will serve you well. 

Final Thoughts

No matter which catamaran you decide to buy for your journey, you’ll be able to sail safely and comfortably. Catamarans are great yachts for long-distance sailing, and the ships on this list are the best of the best. These brands are time-tested and ready to accompany you on an adventure around the world! 

Here are Some of My Favorite Catamaran Cruising Resources

Sailboat Hulls: Steel Vs Fiberglass

Last Updated by

Jacob Collier

August 30, 2022

For decades, sailors and boat owners have been having hotly contested debates about the merits of steel hulls vs fiberglass hulls in sailboats.

The major benefits of boats with steel hulls are that they are very strong, durable, and can be repaired easily. On the other hand, a fiberglass hull offers your boat a smooth and sleek look that is very pleasing. They are also lighter, faster, and require less maintenance than steel boats.

Whether you are building your own sailboat or thinking of buying one, getting the right material for the hull is of paramount importance. Your choice of material should depend on consideration of multiple factors, including its durability, stability, maintenance, repairs, weight, comfort, safety, and cost.

We have a team of sailing experts who have spent decades on the water and have set sail on boats built of all types of materials available. So who better to walk you through the pros and cons of steel and fiberglass hulls?

Table of contents

‍ Steel Hull vs Fiberglass Hull: Top 10 Factors to Consider

Let us take a look at some of the major factors that can help you determine whether a boat with a steel hull or fiberglass hull will be a better choice for you.

Sailboats with steel hulls are much more durable and stronger than those with fiberglass hulls. Steel sailboats have a more rigid structure and are quite robust so they can better understand grazes, rubs, and bumps when out in the open water.

In case of impact, a steel hull will bend and may become dented; however, a fiberglass hull has a higher possibility of breaking. That’s because steel is more ductile and can withstand strong blows without losing its toughness.

Fiberglass is a lighter material than steel, making  fiberglass boats  lighter. Many people prefer this quality since it means that the boat will travel faster on water and will require less power and wind energy to move than a boat with a steel hull. This means lower fuel consumption and more savings. However, a fiberglass boat will be more prone to be buffeted by the winds since it is lighter.

Anti-Corrosion Properties

The sailboat manufacturing industry now uses state-of-the-art technology and makes use of the best quality materials to make the hull. Steel corrodes when exposed to the atmosphere. However, if the right alloy is used for making the hull, it will resist saltwater corrosion, without even needing special paint.

Steel boats also experience electrolytic or galvanic corrosion, but they can be avoided with the use of insulated electrical connections and sacrificial anodes.

Fiberglass does not corrode. However, it can still suffer from osmosis if the fiberglass had air bubbles at the time of lamination. This can cause water to collect in the void, forming blisters that can weaken the hull. Fiberglass may also become damaged from ultraviolet radiation.

Since steel boats are heavier than fiberglass boats, it means they are more stable on the sea, particularly if you experience choppy waters. A fiberglass boat, on the other hand, is lighter, and hence sailors may experience a rougher journey on choppy waters.

In addition, due to its extra weight, steel boats drift slower and more predictably, which is particularly useful for anglers.

Maintenance

Many steel boats require greater maintenance since they are more prone to corrosion. Galvanic corrosion can occur when two different metals are placed together. Hence, it is important that you ensure that high-quality materials, joints, and screws are used on the hull. It is important to rinse the hull with fresh water once it is out of the sea.

Fiberglass boat hulls do not have welds and rivets and you do not need to worry about the hull rusting. However, it can experience osmosis issues, which can cause serious problems if they are not treated in time.

Both fiberglass and steel boats require antifouling application to prevent barnacles, algae, and other sea organisms from sticking to the hull. However, antifouling can be more expensive for steel boats.

It is easy to repair small dents in steel boats. However, if the damage is extensive, it can be more complicated and costly to repair or replace large sections of steel hulls. Welding a boat hull is a specialized job that requires trained professionals.

It is easier to repair a broken fiberglass hull, but it may never have the same strength and durability as the original hull since the structural tension will not be equal at all points.

Fiberglass boats are made of petroleum-based products that are flammable. Hence, in case of a fire, they will burn easily and quickly. A steel boat is much safer since it cannot burn. In addition, a significant impact from an unidentified floating object can result in a breach in a fiberglass hull easily and open up a waterway into the boat that can cause it to sink. Steel, on the other hand, can withstand larger impacts without compromising the integrity of the boat.

Steel boats operate much louder than fiberglass boats, especially in turbulent seas at high speed. Steel is also a good conductor of heat and if it is not well-insulated during construction, it can become uncomfortably warm in the summer and cold in the winter. On the other hand, boats with fiberglass hulls do not transmit heat well and are more comfortable.

When it comes to aesthetic appeal, fiberglass hulls have a sleeker, shinier, and more polished look. Steel hulls often have marks of reinforcements on their hulls and they need to get a nice paint to look good. In most cases, steel hulls are covered with putty to hide any construction defects. This putty should be polished so that the boat has a nice finish and is done in a controlled environment to keep out dust.

As you can imagine, this process is complex, costly, and drives up the price of the boat.

It is easier to manufacture fiberglass hulls and mold them into more complex shapes. This can lead to faster production and lower construction costs. Sailboats with steel hulls are more expensive, as we mentioned before because  they require welding, heavy-duty grinding , and specialized cutting tools and are more labor-intensive.

When Should You Choose a Steel Boat?

Steel hulls are stronger, durable, and more impact-resistant than their fiberglass counterparts. Dents in steel hulls can be repaired easily and although steel is prone to corrosion, this can be managed by special paints, insulation, and some regular maintenance.

If you are deciding on a circumnavigation or want to go out on a long spree in the water, you need a solid and dependable boat that you can rely on when you venture into new territories.

A well-maintained sailboat gives you the confidence to enter into unfamiliar rocky coasts and reduce your worries about hitting UFOs. However, keep in mind that steel boats may be slower than fiberglass boats, particularly if they are smaller vessels.

When Should You Choose a Fiberglass Boat?

Fiberglass boats are generally prettier than steel boats since they have a smooth and polished hull. They also do not require protective paint on their hull since they are corrosion-free and hence quite low maintenance. In addition, they are lighter and faster than their steel counterparts and do not cost as much.

However, one big concern of a fiberglass hull is that it is not as strong as a steel hull. If the boat hits a hard object, the fiberglass may break, which can be dangerous on the open seas, particularly in choppy waters.

Still, fiberglass boats are an excellent option for racing and even long-distance cruising in areas that do not have sharp rocks.

The type of sailboat you choose depends on your sailing style and your needs. So make sure you consider all the factors before you invest in a steel or fiberglass boat.

No, is the short answer. It's just too heavy. A typical 10m catamaran might be built in 9mm ply. This weighs about 1lb/sqft. In comparison, 4mm steel plate - the thinnest you can use for boatbuilding, weighs about 7.5lbs/sqft! Clearly a boat built in steel will be far too heavy for any normal boat. However, some large catamarans (say over 45') have been successfully built in aluminium.

Having said that, most people want a wood interior while condensation is a problem on all metal boats. Thus significant extra non structural weight is added to the shell which compounds the problem. Also don't forget that the cost of the hull shell is only about 30% of the total cost, so any material savings will only have a small impact on the total budget.

Introducing the most exciting performance-focused catamaran to hit the sailing world, the Open Waters 40 is an all-electric catamaran that leverages the latest in yacht construction technologies designed to maximize the thrill of sailing yet still provide the creature comforts of a multihull.

Great handling and speed.

The ESC40 is a 40-ft catamaran designed to be two to three times faster than the typical cruising cat – using carbon fibre to reduce weight and provide increased hull strength.

The twin helm stations are covered by a solar cell-covered roof and come with a 59m2 main sail in addition to three headsails: Jib 26 m ² , FRO 65 m ² and Asail 121 m ² .

The hull is rated to handle boat speeds in excess of 20 knots. With curved retractable daggerboards providing better upwind handling and performance at speed.

The retractable rudders, together with the low draft of 2 ft, allow the boat to cruise in shallow waters and to be beached on the bow or stern.

Regenerative Energy

Thanks to the low weight, higher boat speed and the solar/hydro regeneration systems on-board. The boat is a 100% energy self-sufficient.

The twin electric drives and advanced battery technology allows for quiet, fossil fuel-free cruising.

Each hull features three deck hatches and six portlights for excellent ventilation while the trampoline across the beam is 305 ft ² of play, relaxation and dolphin viewing.

Our unique construction techniques allows us to manufacture the boat in Canada in a quarter of the time compared to traditional boat building.

We can also build and ship your boat in as early as four months, greatly surpassing the industry standard of 12+ months.

From order to build and delivery, our price compares very favourable to other fast cats.

Faster, cheaper delivery

The boat can be packed in a standard 40ft freight container and be shipped safely anywhere in the world at a much lower cost (up to $50,000 savings) and in a fraction of the time.

Boat owners can now also ship their boat one or both ways between North America, the South Pacific, Mediterranean or the Carribean for a one way cruise or an overwintering.

Vacuum Resin Infusion

Vacuum resin infusion is the process at the heart of our technology and is used for all parts.

The vacuum resin process removes all of the air between the fibres of a part prior to the introduction of the resin.

After the process, our parts are meticulously sanded with variable grit — allowing for maximum paint adhesion on surfaces and smooth, stylish edges.

Core Materials

Core materials are introduced into the part to increase stiffness without increasing weight.

The core is a structural-grade foam with a high shear strength characteristic: if the part is of a complex shape, we cut the foam into sections, thermoforming it to the required shape.

We use five different sizes and densities of foam on the boat, optimized for local strength requirements.

We purchase carbon fiber by the roll and over 35 rolls are used in each boat. We have engineered the laminate schedule to be most efficient in the various areas of the boat maximising strength and reducing weight.

Each meant to be the most efficient for their respective areas. The fabrics are stitched, instead of weaved.

Stitched fabrics do not need to bend over or under other fibre and lay flat, making a stronger part.

At Open Waters, it is our mission to make catamaran cruising more exciting and environmentally sustainable. We’ve set out to create a performance cruising catamaran that will be a joy to sail and that will raise the bar in environmental sustainability.

We have developed a unique  design and manufacturing process, selected high performance  materials that enable us to build a boat that uses less materials and is 50% lighter. As a result it is a lot faster and as a result it is able to generate and store the energy needed to propel it electrically for hours and provide enough energy for on board equipment.

We use high performance carbon fibre and a vacuum infusion process to maximize strength and reduce the use of resin and eliminate resin vapour emissions. We use 100% recycled PET foam core wherever possible and we see the opportunity for incremental use of bio-based epoxy and natural fibres in our future.

As we continue to develop our sustainability roadmap for our boats we will perform a full lifecycle analysis to identify other opportunities to minimize our carbon footprint. 

The unique processes and skills we have developed can be applied and licensed to other marine and recreational vehicles businesses.

The Ultimate Guide to Choosing Between a Sailboat or Catamaran for Your Sailing Adventures

C hoosing between a sailboat and a catamaran for your sailing adventures is a significant decision that depends on various factors, including your sailing preferences, experience level, budget, and intended use. Here's an ultimate guide to help you make an informed decision:

1. Sailing Experience:

• Sailboats: Typically require more skill and experience to handle, especially in adverse weather conditions. Ideal for sailors who enjoy the traditional feel of sailing and are willing to invest time in learning and mastering the art.
• Catamarans: Easier to handle, making them suitable for beginners. The dual-hull design provides stability, reducing the learning curve for those new to sailing.

2. Space and Comfort:

• Sailboats: Generally have a narrower beam and less living space. However, some sailboats may offer comfortable cabins and amenities.
• Catamarans: Wider beam creates more living space. Catamarans often have multiple cabins, spacious saloons, and expansive deck areas, providing a more comfortable living experience.

3. Stability:

• Sailboats: Monohulls can heel (lean) while sailing, which some sailors enjoy for the thrill but can be discomforting for others.
• Catamarans: Greater stability due to the dual hulls, providing a more level sailing experience. Reduced heeling makes catamarans suitable for those prone to seasickness.

4. Performance:

• Sailboats: Known for their upwind performance and ability to sail close to the wind. Some sailors appreciate the challenge of optimizing sail trim for efficiency.
• Catamarans: Faster on a reach and downwind due to their wide beam. However, they may not point as high into the wind as monohulls.
• Sailboats: Typically have a deeper draft, limiting access to shallow anchorages and requiring deeper marina berths.
• Catamarans: Shallow draft allows access to shallower waters and secluded anchorages, providing more flexibility in cruising destinations.
• Sailboats: Generally more affordable upfront, with a wide range of options available to fit different budgets.
• Catamarans: Often more expensive upfront due to their size and design. However, maintenance costs may be comparable or even lower in some cases.

7. Mooring and Docking:

• Sailboats: Easier to find slips and moorings in marinas designed for monohulls.
• Catamarans: Require wider slips and may have limited availability in certain marinas, especially in crowded anchorages.

8. Intended Use:

• Sailboats: Ideal for traditional sailors who enjoy the art of sailing, racing enthusiasts, or those on a tighter budget.
• Catamarans: Suited for those prioritizing comfort, stability, and spacious living areas, especially for long-term cruising and chartering.

9. Resale Value:

• Sailboats: Generally have a more established resale market, with a wider range of buyers.
• Catamarans: Growing in popularity, and well-maintained catamarans often retain their value.

10. Personal Preference:

• Consider your personal preferences, the type of sailing you plan to do, and the kind of lifestyle you want aboard your vessel.

In conclusion, both sailboats and catamarans have their advantages and disadvantages. Your decision should be based on your individual preferences, experience level, budget, and intended use. If possible, charter both types of vessels to experience firsthand how they handle and to help make a more informed decision based on your own preferences and needs.

The effect of steplike high-temperature treatment (SHTT) on the composition and structure of carbides in the ledeburite eutectic of R6M5 high-speed steel ingots is studied. It is shown that SHTT processes lead to fragmentation and a change in the composition of the primary carbides, which causes their disintegration and a decrease in the carbide size during hot deformation.
