In this article, I will go through the pros and cons of 10 of the best solar yachts and superyachts that you can buy in 2023 and 2024!

It is also important to note that while there are solar panels for sailboats that you can fit on older models, those new boats have been specifically designed to maximize the use of renewable energy.

Most Luxurious + Most innovative solar system

The Eco 80 Sail Catamaran is one of the electric solar boats provided by Sunreef Yachts.

It features a unique “solar skin” that covers all composite structures on the boat, including hull sides, boom, mast, bimini, and superstructure. This green tech makes it possible to place solar panels where it wouldn’t normally be possible (like the hull and any other smaller but useful surface) and provide enough solar energy from every angle.

The boat is 80-feet long (24.38 meters) and includes electric motors that push it smoothly over the water without causing any vibrations or noise.

Besides being solar powered boat, the Eco 80 Sail Catamaran can also be powered by wind and hydropower. It is designed with a sail on its structure, allowing it to tap into wind power and supplement the solar.

The solar powered sailboat generates enough green power not only to propel the boat and keep it moving but also to charge the essential electric water appliances and other water-sport toys.

So far, the Sunreef Yachts Eco solar sailboats have earned a good reputation for being eco-friendly and sustainable. Besides, this solar powered catamaran takes its commitment to the environment a notch higher by using recycled materials , natural fibers, and non-toxic paints to create their boats.

It is no wonder that Sunreef Yachts have been winning environmental awards for so many years. This solar sailboat is one of the most remarkable boats you can ever invest in and it clearly shows the latest advancements in technology .

Prices: about $8 million USD

• The finishing, while being of high standards, doesn’t seem to be at the level of other options in its category.
• Quite costly, with prices starting at about $6 million USD.
• If going for a long cruise during cloudy days you may need to run the generator to keep going.
• The kite sail helps to give some propulsion using wind, but it is less effective than traditional sails.
• The absence of a traditional sail may make the boat a bit less stable, compromising a bit of the comfort while cruising.

Best for world cruising

HH Catamarans is a small boutique boat builder designing some of the most impressive solar boats for cruising, with one of their latest creations being the HH44.

The HH44 is a groundbreaking new boat that is designed to be eco-friendly and efficient.

The boat has a large battery bank that can be charged by solar panels, and also has two electric motors that can be used for electric propulsion up to 7 knots for up to 2h.

The HH44 has an innovative propulsion system named Eco-Drive. This is a parallel hybrid system that combines diesel and electric propulsion for long-range motoring and silent electric propulsion.

The boat also has two diesel engines, which can be used for long-range motoring or to generate electricity. The boat is also designed to be safe, with four propulsion devices plus sails and a large solar array.

The HH44 has a number of technical features that make it a groundbreaking eco-friendly design, including:

• 3 types of propulsion: full electric, standard diesel, and sail.
• 4.2 kWh of solar panels: generating power for recharging the lithium battery bank for solar .
• 10 kW electric motors (5kW each): mounted on the back end of each diesel engine for electric propulsion.
• The diesel engines can be used both for propulsion and as electric generators.
• Possibility to use the propellers to recharge the battery while the boat is sailing. Kind of like using hydropower to charge your solar batteries , pretty cool!

The HH44 is also a performance catamaran thanks to its C-shaped §daggerboards. Daggerboards are an essential component of many sailing vessels, providing both vertical lift and increased upwind sailing performance.

This solar powered yacht features up to 4 double cabins and 2 heads . Not bad for this world-cruising vessel!

If instead, you are looking for a larger boat, HH Catamarans also have other models up to 88ft.

This solar catamaran was also the preferred choice of Gone with the Wynns , a popular cruising YouTube channel. Here’s their announcement video:

Where to buy : HH Catamarans .

• A true performance world cruiser.
• Very resilient with 3 different propulsion modes (electric, sail, and conventional engines) and ideal for offshore cruising.
• It can run silently and without causing pollution.
• More affordable than other solar catamarans, starting from $1 mm USD
• Smaller than other options.
• The improved sailing performance requires narrower hulls, which reduces the available space onboard compared to other traditional vessels of similar size

Best mid-range

The Silent 60 is one of the smaller electric boats made by Silent Yachts. It is designed to be handled by at least two people. The users can either choose to include an additional crew or not.

Despite its outward small appearance, Silent 60 is very spacious and can accommodate a good number of people.

Besides, the electric yacht has a beautiful design that adds to its elegant and luxurious feel. It is usually designed with up to 6 cabins , with each cabin offering every basic amenity you need to have a luxurious stay on the yacht. In fact, the electric solar boat is equipped with everything you need to allow you to live on board permanently!

As someone who loves spending time on the water, I was really excited to learn about the Sunreef 43M Eco: a superyacht that is both eco-friendly and luxurious.

I was especially impressed by the solar power system, which is built into the composite structures of the yacht, and the large hydraulic platform which creates a vast walkaround beach club.

The interior of the solar superyacht is just as impressive as the exterior, with a variety of sustainably-sourced materials and fabrics used throughout as well as energy-saving air-conditioning. The Sunreef 43M Eco can welcome up to 12 guests in the most luxurious conditions.

The most affordable $

The Aquanima 40 catamaran is entirely powered by solar energy. It features creative adaptations and unique innovations that make it eco-friendlier and more economical boat than other solar-powered catamarans. For example, the solar panels installed on the electric catamaran are built in such a way that they can sell any excess solar energy back to shore stations when connected.

The exterior of the Aquanima 40 has an elegant design. Also, the interior is not only aesthetically pleasing, but also very clean and modern.

The boat is designed with 2 single cabins for the crew and 2 double cabins for guests.

Indeed, this solar boat by Azura Marine is one of the most economical and cost-effective options you can go for when buying a solar catamaran.

• Relatively fast.
• Ideal for short vacations.
• The most affordable solar catamaran, starting at about $0.6 million USD.
• Much smaller than other options.
• Not recommended for long cruises.
• Basic looks and layout.

As its name suggests, the Soel Senses 48 is 48 feet long. It has a slender design and is lightweight , making it more economical than most other solar-powered boats.

The boat is designed with two sleeping berths that can accommodate two people each. It also includes a salon that can offer enough sleeping space for four people. 

Compared with most other solar yachts, the Soel Senses 48 has a much smaller size. Its size, adding to its sleek and innovative design, give it faster speed than other solar-powered boats.

It incorporates 12 solar panels installed on the roof ; all these panels generate a combined electrical power of up to 2.7 kWh. The electricity generated by the solar panels is then stored in two batteries which can be easily configured to hold a maximum solar power of 142 kWh.

Like other Soel Yachts, the Soel Senses 48 glides smoothly over water without causing any noise, rattles, or generating fumes.

It has average cruising speeds of 10 knots, even reaching top speeds of up to 18 knots. However, the solar catamaran cannot run at its top speed for long periods.

Both the interior and the exterior of the Soel Senses 48 have a sleek and modern design. Every single component of the solar catamaran has been designed carefully to make it as functional and comfortable as possible. Therefore, when you board on this boat, you can expect to experience one of the best sailing experiences of your life.

The Serenity 64 Yacht features a diesel engine. It is a hybrid solar boat, which means that it can run on either solar power or on diesel.

The diesel engine especially comes in handy when the users wish to achieve faster cruising.

The solar catamaran is a very spacious electric boat and provides plenty of living space. It is built with four luxurious cabins, with each cabin having its ensuite bathroom. And even though the Serenity 64 is smaller than the Serenity 74 model also built by Serenity, it still provided an elegant feel and a smooth sailing experience.

Solar Boats Pros and Cons

The sun is a powerful and free source of energy, making solar power an attractive option for those looking to power their yacht. Solar panels can be used to generate electricity to run the yacht’s lights, appliances, and even the engine. Solar power can also be used to heat water for showers and laundry. But, what are the pros and cons of solar catamarans?

Here’s a quick summary of the solar yachts’ advantages and disadvantages:

One of the main benefits of solar power is that it is renewable and environmentally friendly. Solar panels have no emissions and do not produce pollution. In principle, they also do not require fuel, making them very cost-effective in the long run. Solar power is also very reliable, as the sun is a constant source of energy.

There are a few disadvantages to solar power. Solar panels can be expensive to install, and while they require less maintenance, this can be quite costly, especially when it will come time to replace the batteries. Solar panels also need to be pointing directly at the sun to be effective, so they may not generate power on cloudy days or at night.

But there’s more, let’s see what some sailing experts are thinking about solar catamarans!

Sailing expert’s solar Boat review

Recently, one of the most popular sailing YouTube channels, Saliling La Vagabonde , published a very honest and interesting review of the solar powered yacht Silent 55. Here’s a summary of their experience:

• 7 Days onboard (6 nights)
• Travelled 145nm with an average speed of 7 knots
• Generator used for about 12h (in total)
• Fuel consumed: 208 liters

Here are some interesting observations they made:

• While cruising it may feel less stable than a standard sailing boat because it doesn’t have a sail to stabilize it when hitting the waves.
• For the Silent 55 it was possible to move at about 3 knots by using only the power generated by the solar panels (without using the batteries) on a sunny day. This means that if you are moving the solar yacht around quite frequently, you will end up using the generator quite a lot to produce the necessary power.
• When the batteries are out of power, the Silent yacht is using a (diesel) generator to supply the necessary power to keep the boat moving and to power the appliances.
• A great luxury yacht with all the comforts and going in the right direction for the future of the sector.
• Overall, the Silent Yacht is a great eco-friendly alternative to a power boat , while if you are thinking about cruising around the world, you would be probably better off going for a standard sailboat (or for some of the hybrid alternatives mentioned in this article, like the HH44).

Why are solar yachts all catamarans?

Solar yachts are all catamarans for 2 main reasons:

• Catamarans have a larger surface, which allows for placing more solar panels and also offers more room for the batteries onboard.
• Catamarans have efficient hulls for their size. This reduces their power consumption while moving.

This makes catamarans the ideal platform to build a solar-powered boat.

Modern solar electric boats are undoubtedly an eco-friendly choice in sea travel and a form of green tourism . Not only do these electric boats provide a smooth sailing experience, but they also reduce the release of emissions into the atmosphere, reducing the environmental impact and enhancing sustainability .

Luckily, given their size, solar catamarans can charge themselves (unlike electric cars ), so they can sail indefinitely without the need to stop for refueling.

If you are environmentally conscious and looking to get a boat that is more viable, desirable, and eco-friendly, you may consider investing in one of the solar yachts discussed in this article!

Review: Silent 55, the extraordinary solar powered yacht

• January 18, 2019

Silent Yachts is tapping into the solar zeitgeist and creating a new meaning for the term ‘powercat’.  Sam Fortescue reports

There is a slow, silent revolution under way in the yachting world. It is a revolution that is introducing tonnes of lithium and a sprinkling of silicon to the spec list of new boats. Holding out the promise of silent mobility, plus limitless domestic power on board, it made a big splash at the last Cannes Festival of Yachting – not least thanks to the new Silent 55 catamaran which debuted there.

From the pontoon side, the Silent 55 looks like a typical modern catamaran, with a big coachroof studded with windows and a flybridge helm. Except there’s no mast. Now, bear with me here. I realise that this is a sailing magazine, but we will shortly get back to more familiar territory. The unique qualities of this catamaran only become apparent from up top, where an expanse of solar panels stretches away fore and aft, embedded into the coachroof. The hard top itself carries yet more panels, and can be folded down flush to give an unshaded solar array of 49m2. During the heat of a summer day in the Med, this is capable of generating 10kW of power and up to around 60kWh in the course of the day.

But to make a solar system work in reality, Köhler had to go back to the drawing board on yacht design. The saloon and hulls have extra thermal insulation to keep air-con losses down, and the use of carbon and aramid in key areas helps reduce the overall weight to a decent 17 tonnes (a Lagoon 52 weighs 22.5 tonnes). He has tried to keep windows out of the direct sun with long overhangs and in contrast to the Lagoon’s 12 deck hatches, the Silent 55 has just two.

Holistic design

On the other hand, it has lots of opening windows, to allow a natural draught to do its job. “It’s a holistic approach – you can’t take the batteries and the drivetrain and drop it into another boat.”

Of course, using the propulsion system quickly takes its toll of the boat’s 140kW battery bank. The model on display at Cannes had two 135kW motors, giving you just half an hour of silent motoring flat-out, albeit at a top speed of over 20 knots. More reasonable 30kW engines and a single-digit speed give you greater range. Nonetheless, the electric drive alone isn’t going to allow you to outrun a storm, or race home after a day at anchor, so the boat is designed to work with a generator hidden in the heavily insulated transom of its starboard hull. At cruising speed of around 5-6 knots, Köhler says there is rarely any need to use the generator, citing an owner who has just emailed him triumphantly about a second year totally generator-free. “In the end, you have to compare it to the performance of a sailing boat,” Köhler says. “It is as fast as a sailing boat in similar conditions – after all, there is no wind without sun.” He went so far as to tell me during the sea trial in Palma, Mallorca, that he believed the majority of sailors would happily dispense with the hassle of sails and a rig if only they could enjoy silent motoring and anchoring. “As soon as people realise the incredible concept of this boat, they won’t understand why they ever did anything else.”

The market does not seem to agree with him – yet. Sales of the boat have been good – they have already sold six, five of which are already in the water. But of those, four customers have taken the sail option, which means planting a 19.7m tall mast complete with boom and rigging slap bang in the middle of the coachroof solar array. “I was a bit amazed,” Köhler admits. “The shade from the rig reduces the energy generated by the solar area, while it costs more and is heavier, so consumes more fuel. Maybe it is for optical reasons.” In fact, the shade of the rig slashes the average yield of the solar panels in half. In the Med, that means around 30kWh per day. But perhaps it figures. The typical profile of buyers is an environmentalist who has a Tesla electric car and is “an early adopter who likes to have things before others”. And at low speeds, with modest use of the air-con, the reduced energy generation should still cover daily consumption.

The performance under sail should be reasonable because of the lightweight build of the boat, its broad 8.47m beam and stub keels added to each hull. Control lines are led back via conduits in the coachroof to the flybridge helm station, to make single-handing under sail a possibility.

More interesting, I think, is a sort of halfway-house option using a kite rig. This optimises the performance of the solar panels and gives plenty of propulsion. On the smaller 55 and the 64, Silent Yachts currently recommends a 19m2 kite that costs around €25,000 – a fraction of the cost of a new mast, boom, shrouds and sails. “The sail automatically makes a figure of eight above the boat, and you can steer it with a joystick or an app on an android phone,” Köhler explains. “It can propel the 55 at up to 6 knots, even in light winds.” Perfect for an Atlantic crossing, then.

For the bigger Silent 79, which will hit the water in the summer, a commercial grade Sky Sail system needs to be used – a smaller version of the ones used on cargo ships. This kite can propel the boat at ten knots, but it costs more than ten times as much as its smaller cousin. Both are capable of pulling the boat upwind. So far, so new. But outside the novel energy and propulsion system, the Silent 55 aims to do what many other cruising catamarans are trying to achieve. “Most of our clients order for circumnavigation and long-term cruising,” Köhler says. So the boat is aimed to be as comfortable and capable as possible with watermakers, TVs and an induction hob that all capitalise on the boat’s abundant energy. A flexible configuration allows owners the choice 
of between three and six cabins – the latter designed for charter. The owner’s cabin lies forward of the saloon, under the windows of the coachroof, which provide magnificent views and abundant natural light. There’s a walk-around bed and steps down into the starboard hull give access to an en-suite shower room and heads.

In my view, the best cabin lies aft of this, accessed in the traditional manner down steps out of the saloon. The king-sized bed lies athwartships and the shower is larger than that of the master cabin. There’s more space down here, better headroom and still plenty of light courtesy of the many hull lights.

When I had the chance to sea trial the Silent 55, albeit in motorboat format, I jumped at it. It was a contrary autumn day on Mallorca with 15 knots breeze – just a shame, then, that this wasn’t one of the sailing configured versions.

To start with, getting on board is made really easy courtesy of deep boarding platforms on the skirts. She feels rather square because of that vast, glazed saloon with its deep overhang, and perhaps because of the utilitarian nature of the hard top, which is really about supporting more solar panels. Nevertheless, the side decks are broad and uncluttered. The space up top is designed to concertina down flat, hence the hydraulic rams, fold-down seat back and lowering console. It makes a great sailing position, though, with all round visibility, and is also perfect for sundowners at anchor. When the rain comes down, this feels quite exposed, but there is a fully sheltered helm at the front of the saloon, and it is also possible to drive the boat from anywhere using a tablet thanks to smart electronics. Under power, the handling is superb. The quietness of the motors is astonishing, and I gather they’ll be inaudible on the next boat, which will do away with the gearbox. Even in the aft cabins, directly above the motors, there is no more than a distant hum. The boat responds instantly to the power and the wind seemed to have no impact at all. As with any propulsion system, the power consumption jumps as you pile on the speed – it was sobering to see. At 6 knots, both motors drew 10kW but at 8 knots it was closer to 30kW. I liked the huge saloon with its raised table for 360º views. And the sliding door and window gives great access aft, connecting the saloon and cockpit in fine conditions. The finish was smart and in muted tones, feeling more Scandinavian than German.

Intriguingly, at least it seems to me, Köhler has tapped into something with the concept behind Silent Yachts – but not entirely for the reasons that he expected. Buyers are opting for the sail or kite versions of the boat because they want a comfortable wind-powered craft with abundant, quiet energy on tap. It brings a whole new meaning to the 
term ‘powercat’

A new beginning: the inspiration of Whisper Yachts

After spending an entire year cruising around the world aboard their solar electric motor yacht by Whisper Yachts, Sarah, Thomas, and their son Lucas returned to France, transformed by this unique experience. Their journey, powered by the solar engines of their yacht, exceeded all their expectations, and they came back with new ideas and renewed energy for their future.

The evolution of yachts: from sail to motorization

The evolution of yachts is a fascinating journey through history, marking humanity’s progress in navigation, engineering, and luxury. This evolution mirrors not just technological advancements but also a shift in our relationship with the seas.

• Exploration

A family's quest for sustainable travel

In the pulsating heart of a bustling metropolis, an art gallery transforms into a stage, unveiling the intimate theater of a family. Sarah and Thomas, embodiments of complicity, wander among the artworks, their young son, Lucas, a silent witness to their harmony. Each painting, each sculpture, becomes a chapter in their story, woven with vibrant colors, mesmerizing shapes, and tales whispered to the soul.

Sailing with Whisper Yachts in 2024

This commitment takes the form of an unparalleled sailing experience aboard their solar electric yachts, a perfect fusion of luxury, technology, and ecological awareness.

Returning to nature, an escape from contemporary chaos

In a world where every second counts, where the incessant notifications from our devices constantly remind us of our duties and responsibilities, the anxiety of immediacy has become a tangible reality. Crowded streets, ever-present screens, and the breakneck pace of modern life have created a stifling atmosphere, leaving little room for serenity and contemplation. The relentless waves of often alarming information overwhelm us, leaving us in search of a sanctuary, an escape.

A unique adventure across Mediterranean and Atlantic coasts

As the days turned into weeks and the familiar coasts of the Mediterranean faded into the distance, the family aboard their Whisper Yachts discovered a new dimension of sailing, where sustainability and luxury became one.

Merging luxury with ocean conservation

Since the earliest days of terrestrial existence, the oceans have been the stage for an eternal dance of life. These vast expanses of saltwater, stretching as far as the eye can see, witnessed the birth of the first life forms and have been the silent observers of the evolution of millions of species. These deep and mysterious seas have inspired countless legends, myths, and tales of adventure, reflecting the fascination and reverence they educated  humanity.

Sunreef shows off gorgeous 80-foot solar electric luxury yacht ahead of US debut this month

Eco-responsible shipbuilder Sunreef Yachts had given the public its first glimpse of its new 80-foot solar electric yacht before it makes it US debut in Fort Lauderdale, Florida later this month. The 80 Sunreef Power Eco is a fully-electric luxury catamaran that could very well be one of the most advanced solar electric yachts built to date.

Sunreef Yachts was established in 2002 in Gdansk, Poland where its shipyard and office still operates in addition to a presence in the the UAE. A year into its existence, the company was touting the launch of the world’s first 74-foot luxury oceangoing catamaran with a flybridge and has been innovating ever since.

Today over 140 Sunreef Yachts are sailing waters across the globe, and the shipbuilders clientele includes Tennis great Rafael Nadal , plus F1 champions Fernando Alonso and Nico Rosberg. As the company looks to delve further into electrification, its latest vessel – the 80 Sunreef Power Eco has already garnered a German Design Award 2023.

Its touting some truly unique solar technology you can see below, and if you happen to be in the Miami/Fort Lauderdale area this month, you can check out Sunreef’s solar electric yacht in person.

Top comment by dan b.

To be clear, I'm not a boater and not fond of being on water that much. In my younger days, I did have a couple boats and was on the Mississippi quite a lot as well as a larger lake in NW IL. The thing that I recall not so fondly was the smells and fuels, putting fuel in them, the spills in the water, the nasty exhaust fumes and film in/on the water, etc. That's always bothered me and I feel that the boating industry may be one of the dirtiest as for pollution along with motorcycles. The fact that boats spend so much time baking in the sun makes them totally great for solar.

So I'm happy and grateful for the fact that boats and motorcycles seem to be moving well into the EV power and using renewable energy as well. It gives me hope for the future where people can still enjoy recreational activities while greatly reducing emissions.

In addition to the new images of 80 Sunreef Power Eco above, we’ve learned that its makers are already declaring the solar yacht “world’s most advanced electric luxury catamaran,” due in large part to is emission-free in-house technology.

The 80-foot vessel is propelled by two 360 kW motors, powered by a massive 990 kWh battery bank. Sunreef says these custom-engineered banks offer an energy density less than 5.2 kg per kWh, nearly 30% lighter than the typical systems most commonly used in the yachting world today.

What may be most impressive about this electric yacht is Sunreef’s 36 kWp composite-integrated solar panels, which have been seamless placed along the catamaran’s hulls, bimini roof, and superstructure. Sunreef describes the technology as a “solar skin” around the yacht.

The interior features 4 luxury cabins and customizable layout to comfortably sleep eight guests. unfortunately, that’s all Sunreef is sharing about the 80 Power Eco at the moment, but the public can learn more at the Fort Lauderdale International Boat Show , taking place October 25-29. It’s there that this beautiful Sunreef yacht will make its US debut. If you happen to go and see her up close, please send me pictures. If you buy one… please invite aboard. TYSM.
