Sailing used to be considered as a rather sedate pastime. But in the past few years, the world of yacht racing has been revolutionised by the arrival of hydrofoil-supported catamarans, known as “foilers”. These vessels, more akin to high-performance aircraft than yachts, combine the laws of aerodynamics and hydrodynamics to create vessels capable of speeds of up to 50 knots, which is far faster than the wind propelling them.

An F50 catamaran preparing for the Sail GP series recently even broke this barrier, reaching an incredible speed of 50.22 knots (57.8mph) purely powered by the wind. This was achieved in a wind of just 19.3 knots (22.2mph). F50s are 15-metre-long, 8.8-metre-wide hydrofoil catamarans propelled by rigid sails and capable of such astounding speeds that Sail GP has been called the “ Formula One of sailing ”. How are these yachts able to go so fast? The answer lies in some simple fluid dynamics.

As a vessel’s hull moves through the water, there are two primary physical mechanisms that create drag and slow the vessel down. To build a faster boat you have to find ways to overcome the drag force.

The first mechanism is friction. As the water flows past the hull, a microscopic layer of water is effectively attached to the hull and is pulled along with the yacht. A second layer of water then attaches to the first layer, and the sliding or shearing between them creates friction.

On the outside of this is a third layer, which slides over the inner layers creating more friction, and so on. Together, these layers are known as the boundary layer – and it’s the shearing of the boundary layer’s molecules against each other that creates frictional drag.

A yacht also makes waves as it pushes the water around and under the hull from the bow (front) to the stern (back) of the boat. The waves form two distinctive patterns around the yacht (one at each end), known as Kelvin Wave patterns.

These waves, which move at the same speed as the yacht, are very energetic. This creates drag on the boat known as the wave-making drag, which is responsible for around 90% of the total drag. As the yacht accelerates to faster speeds (close to the “hull speed”, explained later), these waves get higher and longer.

These two effects combine to produce a phenomenon known as “ hull speed ”, which is the fastest the boat can travel – and in conventional single-hull yachts it is very slow. A single-hull yacht of the same size as the F50 has a hull speed of around 12 mph.

However, it’s possible to reduce both the frictional and wave-making drag and overcome this hull-speed limit by building a yacht with hydrofoils . Hydrofoils are small, underwater wings. These act in the same way as an aircraft wing, creating a lift force which acts against gravity, lifting our yacht upwards so that the hull is clear of the water.

While an aircraft’s wings are very large, the high density of water compared to air means that we only need very small hydrofoils to produce a lot of the important lift force. A hydrofoil just the size of three A3 sheets of paper, when moving at just 10 mph, can produce enough lift to pick up a large person.

This significantly reduces the surface area and the volume of the boat that is underwater, which cuts the frictional drag and the wave-making drag, respectively. The combined effect is a reduction in the overall drag to a fraction of its original amount, so that the yacht is capable of sailing much faster than it could without hydrofoils.

The other innovation that helps boost the speed of racing yachts is the use of rigid sails . The power available from traditional sails to drive the boat forward is relatively small, limited by the fact that the sail’s forces have to act in equilibrium with a range of other forces, and that fabric sails do not make an ideal shape for creating power. Rigid sails, which are very similar in design to an aircraft wing, form a much more efficient shape than traditional sails, effectively giving the yacht a larger engine and more power.

As the yacht accelerates from the driving force of these sails, it experiences what is known as “ apparent wind ”. Imagine a completely calm day, with no wind. As you walk, you experience a breeze in your face at the same speed that you are walking. If there was a wind blowing too, you would feel a mixture of the real (or “true” wind) and the breeze you have generated.

The two together form the apparent wind, which can be faster than the true wind. If there is enough true wind combined with this apparent wind, then significant force and power can be generated from the sail to propel the yacht, so it can easily sail faster than the wind speed itself.

The combined effect of reducing the drag and increasing the driving power results in a yacht that is far faster than those of even a few years ago. But all of this would not be possible without one further advance: materials. In order to be able to “fly”, the yacht must have a low mass, and the hydrofoil itself must be very strong. To achieve the required mass, strength and rigidity using traditional boat-building materials such as wood or aluminium would be very difficult.

This is where modern advanced composite materials such as carbon fibre come in. Production techniques optimising weight, rigidity and strength allow the production of structures that are strong and light enough to produce incredible yachts like the F50.

The engineers who design these high-performance boats (known as naval architects ) are always looking to use new materials and science to get an optimum design. In theory, the F50 should be able to go even faster.

Catamaran sailing: expert multihull techniques

• Nikki Henderson
• February 18, 2022

Moving to a performance multihull can be a leap for even the most experienced cruiser. Nikki Henderson shares expert multihull techniques.

There has been a huge surge in the sales of performance multihulls and with them a need to know how to handle them particularly when it comes to specific multihull techniques. The market for these boats is broadening; multihull cruisers are upgrading, monohull sailors are upsizing, and even virgin boat owners are tempted.

Over the last 12 months, while coaching for Outremer , I’ve met hundreds of these owners, everyone from young families to retired couples moving aboard a new catamaran and setting sail on a circumnavigation. Handling a performance catamaran is achievable even for a novice multihull sailor. But there is a big difference between just ‘getting by’ on such a boat versus sailing efficiently, safely and in style.

The transition for even experienced sailors can be quite a step up. For a seasoned monohull sailor, the differences are obvious: increased volume and speed, and a lack of heel. Even for an existing multihull sailor, the handling and performance is noticeably less forgiving and requires a shift in focus and technique.

This winter, I set sail on a transatlantic with the new owners of an Outremer 55 . They have previously owned another less performance-orientated catamaran but invited me on board to coach them to fine tune the boat, assist with routing, and help them take best advantage of all the performance their new yacht offers. Here are a few of the topics we focussed on:

sailing at higher speeds will change everything from manoeuvre techniques to weather routing. Photo: Robin Christol/Outremer

Most non-planing monohulls will do approximately the same speed on all points of sail. However, a performance multihull might sail at twice, three, even four times its upwind speed on a reach.

For example, the factory polars of an Outremer 55 give its average speed in 20 knots of wind with a true wind angle (TWA) of 50° at 8.5 knots, but in the same windspeed with a TWA of 110° it’s 19.1 knots. That’s more than twice as fast. How do you make the most of this speed advantage? And how do you best manage it ?

In a monohull it often pays to slog it out for days sailing the best course to windward as this normally gives the best velocity made good (VMG). A dead downwind rhumbline route is the usual strategy for longer ocean passages, rather than sailing more miles and wider angles.However, on a performance multihull it is important to prioritise reaching when route planning.

In upwind conditions on a long crossing, consider whether bearing off by even as much as 20° will result in a better VMG, even if it feels counterintuitive. In light winds bearing off to 70° or 80° TWA can be the difference between a totally stalled boat and 5 knots of boat speed .

Faster speeds open up the possibility of keeping up with pressure systems as they move around the globe. For example, if crossing the North Atlantic eastwards, ideally you’d leave the US in clear weather with a depression forecast to leave the American coast a few days later.

You could use its predicted track to decide how much north or south to add to your easterly heading, to ensure that as it catches up with you, you are sufficiently south enough of it to pick up its strong westerlies. As they approach, you will accelerate, and if you can hold the speed you can use that downwind airflow to push you most of the way across the pond.

Handling at speed

Controlling and handling the boat at these higher speeds requires a change in strategy. Increased speeds and acceleration mean that the apparent wind angle and apparent wind speed change much more frequently. So you need adaptable and flexible trimming and driving solutions.

Use twist to balance power and control. Photo: Robin Christol/Outremer

Downwind the boat should be carving S-curves through the water to ensure it achieves the best VMG possible. If you can get this right you will attain the momentous double figure average speeds that a performance multihull offers, while also going the right direction! Instead of allowing the speed to plummet at the end of each surf, as the bow sinks into the bottom of the wave, a performance multihull can just keep on going.

How to maintain speed:

1 Sail at higher angles to build up apparent wind speed (AWS) and boat speed.

2 Soak downwind as the apparent wind angle (AWA) surges forward with the acceleration.

3 Drive the boat back slowly upwind in time to maintain the average speed and continue the surf.

In an ideal world, to achieve this the boat would be hand-steered. But realistically, no cruisers want to be on deck for two weeks straight on a transatlantic crossing. Your best compromise is to invest in a top quality, well set up autopilot, as well as good wind instruments.

Set the autopilot to sail to apparent wind angle and watch how the boat slaloms through the ocean. The quality of the autopilot will really start to show its value when the sea state starts to increase. The best ones improve over time as they collect data and learn the wave patterns. If you aren’t sure exactly which AWA is ideal, choose a day that has very consistent wind and sail in open water. Set the autopilot AWA to 90° and then systematically increase the setting by increments of 5° at fixed time intervals until you get as low as you can before the foresail is shadowed behind the main. Measure the VMG by comparing the distance travelled at each of the different wind angles, and the average A to B course over ground (COG) achieved. This will give you a good starting point, and then it will shift further depending on sea states and wind strengths.

Sail setting

Another solution if you want fast speeds but don’t want to actively sail the boat to within an inch of its life is to use twist. Twist is a compromise between having a hardened sail that stalls when the wind goes aft, or a very eased sail that luffs when it goes forward. The more changeable the conditions, the more extreme the acceleration increases are, or the rougher the sea state is, the more twist you need.

The wide beam of a multihull allows for a long traveller, so most won’t have a vang. Sheet tension and traveller position are your primary controls to create twist in the mainsail. Begin by finding a full power setting in the main.

Set your autopilot to 35-40°AWA; most performance multis should make this upwind. Set your traveller at midships and over-ease your mainsheet so that the sail is luffing. Gradually tighten your mainsheet until the top telltale just flies. Manual winching offers better control here than electric.

Pull your traveller to windward until the boom runs down the centreline. The top telltale of the mainsail will now be flying about three-quarters of the time. If it is closer to 50% you may need to tighten the mainsheet further and then ease the traveller until you have achieved this (or vice versa). This is your full power sail shape, and your default car position upwind.

At this point some people like to mark the mainsheet (this doesn’t work with a continuous mainsheet). To begin with, just take note of the traveller position. If the conditions require more twist, ease the mainsheet, and pull the traveller to windward to keep the boom in the same position relative to the boat. You could keep a note of three traveller positions for each point of sail: full power, mid power, low power.

As the wind moves aft, you can add other ‘go-to’ traveller positions for different wind angles by easing the traveller down to leeward while keeping the mainsail shape set to ‘full-power’ mode. Once the wind goes aft of the beam, your traveller will be all the way down to leeward. Keep an eye on spreader chafe at this point.

Once you are happy with mainsail trim, you can trim the jib in a similar way, using car position and the sheet tension. Bring sheet tension in so that the leech shape looks very similar to the main: flat with a slight curve at the top. Then adjust the cars (if you can) so that the sail is not luffing, and the top telltales are also flying 50-75% of the time. Finally, walk forward to the forestay and view the slot between the sails. Do they look roughly parallel? If not, you may need to open up the slot a touch by moving the car outboard. This is your default jib car position for that point of sail.

When conditions increase, don’t forget to add twist to the jib too. Initially just ease a touch of sheet. Be careful moving the car too far inboard or you might close the slot. Moving the sheet attachment closer to the foot of the clew will open up the leech and create more twist.

Think of twist as the middle ground between sailing fully powered and reefing. Multihulls are much less communicative than monohulls. You do not have the obvious signs that the boat is overpowered, like a submersed toe rail or rounding up as the boat heels.

In time you’ll get to know your catamaran and build a connection to read how aggressively the boat is accelerating, its fore-aft pitching, sounds, and rhythm. But at first it’s useful to have some number guides and wind parameters of when to add twist and ultimately when to reef.

Generally a performance cat will require a reef much earlier because it’s lighter. I’d usually put in one reef at 20-25 knots, two at 25-30 and three reefs for 30-35 knots.

On our transatlantic crossing on the Outremer 55, contrary to my advice on the advantages of sailing angles downwind, we chose instead to sail dead downwind with the symmetric spinnaker up for the entire passage.

There are costs to taking full advantage of the speed of a performance catamaran. Averaging 15 knots boat speed is not everyone’s idea of comfortable. The hulls are so stiff that every wave that hits the hull sounds like the beating of a drum. The humming of carbon rigging, the swooshing of water screaming past the topsides, the slapping of the waves, the wind: it’s incredibly loud even when averaging 10 knots, let alone 15 or 20.

Performance multihulls are also so lightweight that they are really thrown about in a substantial sea state. Our decision to sail dead downwind rather than heating up and taking full advantage of the performance came down to the following reasons:

1. Lack of adequate autopilot We had one, but it wasn’t able to react quickly enough to the acceleration and resulting rapid change of wind angle that broad reaching would have created. It also struggled in a big seaway, so sailing with the waves square on to the stern was easier to cope with.

2. Sails We did not have a heavyweight asymmetric sail, which is what you need to sail these downwind angles (both our reaching sails were light weight).

3. Safety Akaroa II is hull No2 of a new design by Outremer. This was the first transatlantic crossing that this particular model of boat had ever done, so we were a testing ground and deliberately cautious.

Despite our conservative approach we still achieved 90% of the factory polars averaging 9.6 knots in sustained winds of 20 knots across the entire 2,700-mile route.

The trip took 11 days and 17 hours. The beauty of a performance multihull is that even if you don’t push it, you still manage brilliant speeds in the right conditions.

We calculated how much faster we would have gone, had we sailed the angles instead of running downwind. This assumes we would achieve the same 90% polars. TWA 140° appears to be the sweet spot.

Without any power being dispelled by heeling, performance multihulls will convert additional power into acceleration. With this increased speed comes increased loads on the lines, blocks, rudders, sail cloth and rigging. Winches are upsized. Jammers are used instead of clutches. Halyards are 2:1. You may be sailing on a 50-footer, but the loads are akin to a 70-80ft bluewater monohull.

A future owner recently reminded me of this, when he opened the main traveller jammer while holding the line with only one wrap on the winch. The lack of skin on his hand was gruesome evidence of how surprising the loads can be when a multihull is really powered up.

Interestingly, comparing a standard cruising multihull with a similar sized performance multihull, the opposite is true. A boat that weighs less needs less sail area to power it. For example, a Lagoon 450 has a sail area (main and jib) of 130m2 compared to an Outremer 45 (actually 48ft LOA) at 104m2. So, for the same apparent wind speed, there will be less load on the gear.

Watch out when sailing downwind. Due to a performance multihull’s ability to accelerate and hold high speeds downwind, it is easy to hold significantly more sail area in higher true wind speeds as the apparent stays low. However, if you do hit the bottom of a wave and stop dead in the water, the sail, rigging and lines will feel the full force of that wind.

Another reason to reef earlier than you think on a performance multi is that with swept back shrouds (needed to support the mast without a backstay) and a fully battened mainsail, even with the halyard eased downwind the sail may still not come down. You should be sailing with the minimum amount of sail cloth up to achieve the polars.

Reducing sail

1. Rig up downhaul lines from each reefing point on the luff to help grind down the sail. Keep an eye on chafe on the leeward side on each of the batten pockets.

2. Use the rotating mast to open the sail to the wind more.

3. If that isn’t enough, come upwind to help get the sail down.

Multihull trim

Switching to a performance catamaran may bring new trimming options: daggerboards, a rotating mast, and fully battened square topped mainsail.

Brush up on your fundamentals of sail trim so that you have a solid foundation to build on. When you first start sailing the boat, to avoid getting overwhelmed (which tends to result in people under-sailing their boat), begin by finding a base setting for all points of sail. Forget the rotating rig for now, but find enough twist in the sails that gives you enough height without too much power. Set the daggerboards as you would on a dinghy: down for upwind, up for downwind, mid-way for a reach. Then you fine tune.

Set performance cat daggerboards as you would for a dinghy at first: down for upwind, up for downwind, mid-way for a reach. Photo: Nikki Henderson

When adjusting daggerboards, make sure you have your GPS track switched on. See if dropping a little more daggerboard helps with the COG upwind. Downwind, if you feel like you are on an ice-skating rink, try dropping a little board for better grip. If on autopilot, take note of the rudder angle. If it’s taking the helm from full starboard to full port then it might need some more grip, if not then a reef.

Be cautious of the risk of ‘tripping up’ in big seaways. In sea states much over 3-4m, it’s safest to lift the daggerboards and allow the boat to glide over the waves rather than risk one of the boards digging into a wave and destabilising the boat. While exceptionally unlikely to happen, if a daggerboard digs in, the worst case scenario would be a capsize. If you see any slick in the water that suggests the boat is sliding sideways over a wave, or an increase in heel, or significant water over the deck – these are signs that it’s time to lift the boards all the way up.

Finally, play with the rotating mast. At a basic level, try to get the mast in line with the foremost sail position and curve. The easiest way to see this is actually to stand forward of the mast and look down the line of the sail. It is in itself a foil and when in the right position can add the equivalent of as much as 10% more sail area. In the same way, you can use it to depower by reducing the angle.

With a rotating mast you’ll generally be trying to get it in line with the foremost sail position and curve. Photo: Nikki Henderson

When fine tuning sail trim I’d recommend marking all your tracks and angles of mast rotation, and once you are confident you could mark the sheets and halyards themselves. This is an exercise for the detail-orientated and it pays to be specific. Keep a notebook at the helm station to record your learnings, and over time build up not just ideal trim settings for wind and waves, but also polars.

The best bluewater multihulls of all time: a complete guide

What are the best bluewater multihulls for long term cruising? The one you own, or the one you can afford…

Learning a performance catamaran’s sensitivity to weight can be a real learning curve. Compared to cruising catamarans, performance cats tend to be half the weight (or even less). Meanwhile, compared to a monohull the main difference is in the areas where the weight is most concentrated. A monohull’s weight is predominantly in its keel. Almost the entire weight of the boat is concentrated in around 15% of the boat’s length. Conversely, a multihull has no keel, so without that pendulum effect its centre of gravity is higher and less stable. On a multihull the weight is distributed along almost 90% of its length.

In practice, this means that what you carry, both below and above decks, has a big impact on the boat’s performance and safety. The first step is to become minimalists. Summon your inner Marie Kondo and ask yourself “Does this bring me joy? Does this keep me safe?” of every single item that moves from dock to boat. If it doesn’t – don’t take it.

Performance cats are weight sensitive so streamline your possessions onboard. Photo: Carl Newton

Step two is to arrange your belongings evenly around the boat. Ensure you don’t list the boat to port or starboard. Try to keep weight amidships and ideally low down. Avoid loading up the bow lazarettes or aft areas with too much weight.

When sailing, don’t forget that the worst kind place for weight is aloft. Without the keel, you significantly reduce the stability of the boat by having a furled Code 0 (for example) hanging around up the rig. It’s inconvenient to drop it every time, but it’s worth it.

Higher speeds, bigger loads, a lighter boat and higher centre of gravity don’t sound like the safest characteristics, and they aren’t if poorly managed. But you can also use them to your advantage. Being able to sail faster means you sometimes have an option to run away from bad weather.

But there are other safety drills that are worth thinking about ahead of time. What is your MOB recovery plan? With cats’ high freeboard, some owners plan to reverse up to the casualty and pick them up from the steps at the back. But how many have practiced that? Will it involve dropping the mainsail? Could the props injure the casualty? How does the back of the boat behave in a significant sea state? I’d recommend practising this until you have a plan that works for you on your boat with the equipment you have. The same should be said for plans to evacuate the boat, or deal with a fire on board.

12 Best Catamaran Sailboats

The appeal of the catamaran sailboats in terms of speed , stability, and the ability to embark on long-range cruising has made them hugely popular with today's sailors. But what are the best catamaran sailboats?

Even though catamaran sailboats have become increasingly popular in the last few years, they have a truly rich legacy as one of the most sought after vessels for bluewater cruising.

Thanks to their incredibly wide beams and bigger daft, catamarans have become remarkably favorable for sailors looking to go for long-distance voyages, overnight cruising, and day sailing.

And if space is paramount for you when out there on the water, a catamaran sailboat is the only way to go as they offer extraordinary space to allow you to spend more time on the water with friends and family.

But even with all these amazing features, you're probably still wondering; what are the best catamaran sailboats?

Like their monohull counterparts, choosing the best catamaran sailboat can be quite overwhelming since there are lots of them out there. They come in a wide variety of designs and sizes ranging from small catamarans to huge ones.

The best catamaran sailboats can easily clock 250-mile voyages, offer incredible performance, and have layouts that can be easily optimized for individuals, charter markets, and great accommodation. In essence, the best catamaran sailboats offer respectable performance and offer good load-carrying ability.

That being said, here are some of the best catamaran sailboats that you can get your hands on.

Best Catamarans

{{boat-info="/boats/manta-42"}}

Even though many multihulls are no longer built in the United States these days, the Manta 42 is a true American-built catamaran that brings good living and good value into one package. Designed cleverly for easy handling, this American built catamaran is a great choice for a liveaboard cruiser for sailors looking to go for long-distance voyages. Thanks to its trademark high bows and an enormously curved incorporated forward crossbeam, this catamaran is easily recognizable even from a distance.

It is designed with a uniquely fixed crossbeam, which is very different from conventional aluminum cross beams that support the tension of the forestay. This fixed crossbeam allows for a little bit of movement thereby helping in absorbing enormous twisting forces of the bows. As such, you have to keep in mind that there may be resultant stress crack particularly in the bow area of the vessel.

All in all, the Manta 42 is a superb offshore cruising catamaran that offers a good sail-area-to-displacement ratio as well as plenty of space and accommodation. The cockpit area is refined, luxurious, and is designed with additional stainless pushpit contraptions to help in holding objects such as wind vanes, dinghies, and solar panels. The boat's quality in terms of performance and stability is the benchmark of what a catamaran should be.

Fountaine Pajot Elba 45

{{boat-info="/boats/fountaine-pajot-elba-45"}}

Recently named the "Boat of the Year" for 2019 by Cruising World Magazine and Sail Magazine, the Elba 45 is the latest model in the incredible line of Fountaine Pajot catamarans. This boat was designed to replace the outgoing Helia 44 and stands to be one of the most popular catamarans with Fountain Pajot having sold over 100 Elba 45 hulls long before even the first one emerged from production.

This French-built cat brings to the fore a well-thought-out, safe, and dependable features with 10% less drag, efficient motoring, top-notch performance, and high speeds. It's also designed with fixed stub keels and slightly aft-raked bows, which are all essential in enhancing windward performance; something that most catamarans struggle with.

To improve on safety, the keels of this amazing catamaran sailboat are glued into a particularly designed recess in the hulls. This is to ensure that there are no keel bolts that can rip out and put the boat in danger if the boat gets grounded or in the event of a collision. The rig is also ICW friendly and is a true representation of a standard catamaran setup.

This is, without a doubt, a modern-looking cruising catamaran that has a low-profile lounging space on its deck, high topsides and bows as well as a more pronounced reverse sheer that's essential in minimizing the bulk of the windows while creating additional and useful volume below. This is a true catamaran that occupies a sweet spot for those looking to sail along the bay or for those adventurous sailors looking to set sail for more ambitious offshore cruising plans.

{{boat-info="/boats/leopard-48"}}

With its fine design, straightforward systems, and easy handling, the Leopard 48 has everything it needs to be ranked among the distinguished category of the best catamaran sailboats. This is an excellent multihull that is structured with advanced materials, designs, and innovations that are meant to be fun, spacious, and comfortable.

Designed in South Africa by Simonis-Voogd, is probably the best design in the Leopard family of catamarans. Its two hulls are vacuum-bagged using balsa core to offer maximum firmness while ensuring that the weight is on the minimum. This is done by articulately regulating the level of resin in the layup. With such types of hull shapes, this catamaran sailboat is very fast and can consistently clock 12 knots of speed against the currents.

The boat is also designed with shallow keels as they're filled with closed-cell polyurethane foam that's of great importance in increasing buoyancy and preventing water ingress. To enhance the safety of the vessel, the stern and bow both have bulkheads that are essential in keeping out that water if the sailboat is involved in a collision.

The hulls of this boat are deep and narrow, particularly below the waterline. They also curve higher up to practically reduce the wetted surface area while offering enough deck space and plenty of room for accommodations. Its cockpit is another excellent feature thanks to its lavish spaces that give you the chance of kicking back and relaxing.

This boat is designed to offer superior livability, quick and easy to handle features, as well as enough space for friends and family. It is designed with beautiful lines and immense practicality for those who want to go on long cruising voyages.

Antares 44i

While many people often believe that voluminous cruising catamarans should be used as charter boats, the Antares 44i brings a very different perspective altogether. Designed in Argentina as a complete bluewater catamaran, this is a boat that's specifically built for private boat owners looking for a sturdy and well-equipped bluewater cruiser. This is an absolutely gorgeous catamaran that has a fully-equipped cockpit just to ensure that you can safely operate it even when shorthanded.

Like most catamarans, the Antares 44i is designed with features that allow for long-distance voyages. It comes with a minimum bridge deck clearance of 30 inches, which is essential in mitigating bridge deck slap. The helm station is designed to offer excellent visibility over the coach roof without having to perch the helmsman high above the cockpit.

If you're planning to make those long-distance cruising to exotic places, you'll appreciate this boat's layout. The galley is put down in the port hull so that it doesn't compromise the size of the galley and the saloon. The forward-facing navigation station is up there with the best and is up to offshore standards. And that's not all; the Antares 44i comes with good mounting points for electronics, a large table, comfortable seats, and provides brilliant visibility outside.

This boat is perfectly suited for extended offshore cruising and is a great reminder for anyone who thinks that all catamarans are charter boats and all offshore boats are monohulls.

{{boat-info="/boats/dolphin-ocema-42"}}

Designed by Philipe Pouvreau in northern Brazil, the Dolphin Ocema 42 is a truly unique catamaran sailboat that goes against the conventional norm of catamarans. It is equipped with daggerboards, which are essential in enabling it to point higher on the wind while reducing the wetted surface when running or anchoring in shallow surfaces. This, however, requires a higher level of expertise in sailing. This is because lifting the daggerboards higher up will expose the rudders while the daggerboards can also interfere with the hulls in the event that the vessel runs aground.

But even with that, the Dolphin 42 balances incredible performance and cruising comfort in a very compact package; something that is not very easy in bluewater cruising. That's why it's designed using a foam core to make it lightweight by reducing weight wherever possible. This vessel will most likely never let you down if you want to circumnavigate the bluewater on a high-performance boat that is safe and comfortable.

So if you've been looking for a real sailing catamaran that doubles up as a very comfortable liveaboard sailboat , look no further than the Dolphin 42.

{{boat-info="/boats/catana-50"}}

Regarded as the best built and most stylish cruising multihull, the Catana 50 is a very huge catamaran sailboat. Measuring about 50 feet long with a beam of about 26 feet, this is an amazing catamaran that will test your sailing skills as a single sailor or if you're planning to sail shorthanded.

This boat is designed with a rig that gives you the option of using either a screecher or a self-tending jib. This may seem complex since the sheets are led to winches near each wheel while all other controls lead to a centerline winch that's located in the cockpit. But even with that, this sailboat can be easily tacked once on the course.

This is a real performance-oriented catamaran with efficient hulls and rigs allowing for top speed. This vessel is also designed with a long waterline and a subtle underwater shape at the bow to help in increasing volume while minimizing wave drag. The stern platforms can help in stretching the waterline length while also providing easy access from a dock or a dinghy. The board trunks are also very strong and sturdy to protect the integrity of the hulls if a collision occurs.

In essence, this is a very modern catamaran that's designed to safely make long-distance passages with ease. It is subdued in terms of styling but this doesn't mean that it falls short as far as performance is concerned.

Atlantic 42

{{boat-info="/boats/atlantic-42"}}

Designed in 1993, the A42 has cultivated a legion of fiercely loyal fans thanks to its efficiency and aesthetic. This is the smallest of the Atlantic cruising catamaran line and is hugely popular with sailors thanks to its ease of handling, ocean-going capabilities, and superb use of space. From the forward cockpit, pilothouse to the sleeping cabins, and brilliant galleys everything about this cat is a true classic.

Unlike most catamarans, the Atlantic 42 is designed with a waist-high cockpit that's located forward of the pilothouse just behind the mast. It brings forth a solid construction thanks to the large metal girder-like bearers that run across the bulkheads. This helps the vessel in having the utmost strength, better air circulation under the engine, and a high level of flexibility as far as the size of the engine and its positioning is concerned.

Initially, the boat's style and its outlook were considered conservative but it soon became clear that it is built of high-quality materials and to last. The internal construction of the boat is impressive, to say the least. The exterior looks very beautiful and perhaps much more beautiful than most boats today. Its large aft cabin accommodation is a top drawer while the space separating en suite heads and shower compartments are considered a bonus.

{{boat-info="/boats/fountaine-pajot-bahia-46"}}

This cat remains very popular among sailors thanks to its easy handling features and incredible performance under the sails. Well, this may not come as a surprise to many of us given that the Fountain Pajot is known for building some of the most remarkable cruising catamarans out there that it can be quite overwhelming to narrow down to a single vessel, but the Bahia 46 simply stands out.

This vessel is designed with hulls that are broader than those of many other catamarans. It's also designed with centerboards and daggerboards that are meant to enhance its performance. These are essential in minimizing draft while ensuring reliability, generous bilge, and in helping to protect the rudders and propellers.

This boat is big enough to manage any type of serious offshore sailing. This is one of the best cruising catamarans for anyone looking for the right vessel for long-distance sailing. This vessel has a very more generous rig than most cruising catamarans, which is essential in enhancing its performance. The six-post Bimini is very strong and clean and can perfectly hold dinghies.

In terms of its look, the Bahia 36 is designed with gorgeous lines with the deck and hulls sculpted with lines that add a touch of elegance to the overall look of an already excellent catamaran sailboat.

This is essentially a 35 feet catamaran that offers great value for any sailing looking for a reasonably-priced catamaran sailboat for the weekend or holiday cruising.

This boat is designed with incredibly slim hulls, which are teardrop-shaped with flat bottoms and smaller wetted surface area. This is to ensure that drag is minimized and to lead to more leeway under sail. Each of the boat's hull is designed with a kick-up centerboard is of great importance in enhancing the vessel's windward pointing capability. This boat also has its rudders raised to enable it to seamlessly cruise in shallow waters where most vessels would otherwise run aground.

The eccentric narrow beam, which measures about 40% of the boat's length, is very different from today's 50%. However, its low center helps in keeping its stable, upright, and of course, safe.
