electric sailing catamaran

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!

Spanning 115 feet, the newest composite multihull is fitted with Sunreef’s custom-engineered batteries and state-of-the-art electric engines. Solar panels will also be embedded into the hull sides, superstructure, and bimini, allowing the cat to generate power from the sun. The yard has previously added this patented “ solar skin ” to several models, such as the newly unveiled Explorer Eco 40 , the Eco 100 , the Zero Cat , and the 80 Power Eco .

Sunreef didn’t share any details regarding speed or range for the new 35M Eco, but the aforementioned 80-foot cat is powered by 360 kW electric motors that can push it to 10 knots. The newcomer theoretically has an “infinite range,” given it can continuously get power from the sun so long as it’s shining. The clean, emissions-free energy would also power the hotel load at anchor.

The 35M Eco is not only sustainable but also spacious and stylish. With a beam of 48 feet, the yacht offers expansive living areas onboard. Positioned in the bow of the main deck, the owner’s stateroom provides stunning panoramic views and private access to an outdoor terrace. The luxurious guest accommodation, meanwhile, is located in the hulls and is fully customizable.

The 35M Eco offers an abundance of alfresco lounging areas, too. The vast walkaround aft deck, which Sunreef calls the “ocean lounge,” gives seafarers easy access to the sea and a hidden garage stocked with water toys. In addition, the sprawling flybridge features a plunge pool and bar.

Rossinavi Launches 140′ Hybrid-Electric Catamaran

• By Caleb Revill
• May 30, 2024

Italian yacht builder Rossinavi announced the launch of the M/Y Seawolf X , a hybrid-electric power catamaran capable of cruising in full electric mode for 100 percent of the time on one-day trips.

In a press release from the company, Rossinavi announced the innovative yacht carries the BluE label designating the shipyard’s new sustainable philosophy. Seawolf X has a 140-foot length overall, 45-foot beam and is an all-aluminum vessel that combines sleek design with environmentally friendly solutions.

The press release notes that the catamaran can cruise in full-electric mode for 100 percent of the time on day trips and 90 percent of the time on multi-day trips. Rossinavi also states that the vessel is capable of making transatlantic trips while in electric mode 80 percent of the time. 

The Hibernation mode, kicking off when the power catamaran is moored, reduces consumption to a minimum and the energy generated can be given back to the dock or a private property. Rossinavi boasts that the Seawolf X supplies enough energy to charge up an entire villa. The ship’s two diesel generators can quickly recharge its batteries on shore power in five hours.

“After years of study and construction, it is now a source of satisfaction and pride for us to witness the launch of project Sea Cat, now Seawolf X , the first hybrid-electric multihull vessel,” said Rossinavi COO Federico Rossi in a press release. “This yacht showcases remarkable technological innovations in both power management and propulsion technologies, marking the beginning of a new chapter in next-generation vessels.”

Yacht of the future

Rossinavi’s BluE label hybrid-electric yachts are propelled by batteries and solar panels with the goal of reducing CO2 emissions. Energy collected by these solar panels during the day is stored in advanced batteries and released at night, creating a bioluminescent effect similar to glowing plankton.

On top of its environmental perks, Seawolf X also includes an onboard artificial intelligence system developed by Rossnavi. Rossinavi AI constantly analyzes the operation of the vessel and acts as a brain that can learn from observation and predict the needs of the guests on board. Rossinavi AI is able to talk with crew members and monitor the battery pack to keep it in a range of 20 to 80 percent –the ideal range to ensure better battery pack lifespan.

The boat’s exterior architecture is by Fulvio De Simoni Yacht Design , while New-York-based practice Meyer Davis Studio designed the interiors. The Fulvio De Simoni Yacht Design team came up with a sleek and low-profile silhouette, reminiscent of a sports car.

The yacht has three distinct spaces for outdoor living: a lively cockpit centered around a pool, a large sundeck with sunbathing and living spaces, and a bow area featuring a hidden pool and convertible home theater. The yacht design team accurately integrated solar panels into the vessel, ensuring plenty of surface space for energy recovery.

“We set out to envision the boat of the future, unbound by convention yet grounded in feasibility with cutting-edge technology for minimal environmental impact,” said Fulvio De Simoni, founder of Fulvio De Simoni Yacht Design, in a press release.

The Revolutionary Electric Catamarans Introduce Zero Emission Cruising

With greater awareness about pollution, sustainable and emission reduction practices have become increasingly salient in the maritime industry. The International Maritime Organization envisions a reduction in CO2 emissions by 40 percent by 2030 across international shipping to combat climate change.

The nautical sector has found a promising solution with the invention of electric catamarans. These vessels are powered by electrical energy, offering a more ecological, energy efficient, and environmentally friendly alternative to traditional cruising.

Making The Switch to Electric Catamarans

Electric catamarans are propelled by electric motors that draw power stored in lithium-ion batteries. These massive batteries are replenished by solar panels, wind turbines, hydrogenators, or a combination of all, allowing electric catamarans to ply oceans with an extended range.

Sunreef Yachts Eco remains at the forefront of eco-friendly responsible yachting with their electric sailing and power catamarans . The shipyard has made impressive strides in pursuing green energy generation for sailing the blue waters, including the installation of battery banks of the future and utilization of renewable energies.

What Makes Electric Catamarans Convenient?

1.  questing for unpolluted waters.

Did you know that one litre of oil is capable of polluting one million litres of water ? What is more is that catastrophic oil spills only account for five percent of the total water pollution, the rest of the major chunk is avowed against engine emissions, oil leaks, and refueling from waterborne vessels. This oil contains hydrocarbons and heavy metals that damage the aquatic environment and adversely affects human health.

To avoid contamination, eco-conscious yacht builders and manufacturers, like Sunreef Yachts Eco, have launched electric catamarans that are less likely to harm wildlife or water users. With electric catamarans, there are no risks associated with spilling fuel as they need not make their way to an oil pump for replenishing.

Apart from rising concerns of water pollution, the traditional marine outboard engines are also known to have detrimental effects on marine wildlife due to the noises generated. This noise impacts breeding cycles, hinders navigation of partially sighted animals, and prevents fishes from hearing their predators. As counterparts, electric engines boast quieter operations, thus minimizing adverse effects on wildlife and making the voyages more pleasurable for yachting enthusiasts.

2.  Greater Environmental Sustainability

An electric catamaran’s engine contributes significantly to a reduced carbon footprint that combats climate change effectively without releasing exorbitant levels of toxic pollutants, such as carbon monoxide, hydrocarbons, and nitrogen oxides, which deteriorate air quality.

3.  Energy Efficiency

Electric propulsion systems tend to be more energy efficient than the traditional internal combustion engines. This is because the extraction of fossil fuels from deep within the Earth, refinement, transportation via great distances, and distribution to oil pumps, accounts for a staggeringly high consumption of energy.

Additionally, the overall energy efficiency of a diesel engine is often capped at 40 percent; the rest of the 60 percent is lost in the name of heat and friction. On the other hand, electric catamarans can be charged directly from the grid, providing renewable electricity, to be more environmentally friendly. This accounts for lower operating costs overall.

Sunreef Yachts Eco employs the latest in yacht building technology to ensure efficient power distribution and hull form. The lightweight hull of our electric catamarans guarantees instant power with little to no drag, resulting in least possible wasted energy.

4.  Lower Maintenance Cost

Electric catamarans require relatively lesser maintenance as they boast fewer moving parts that use low friction magnetic field for operations and experience close to zero vibrations compared to internal combustion engines. They eliminate the need for winterization maintenance, oil changes, and filter, gaskets, or impeller replacements.

Alongside this, replacing greenhouse gas emitters, such as petrol and diesel, is certainly more economical. This also accounts for electric catamarans having a greater resale value on the market.

Understanding The Role of Marine Batteries 

The primary reason why consumers avoided plowing waters with electric catamarans back in the day was the limited range that made variable sea states hazardous. What made the situation worse was their slow charging abilities at limited marinas around the world.

However, the electric catamarans of today offer smooth and silent operations, excellent maneuverability, and emission-free functioning. Additionally, they have torque from the second their shaft is engaged, enabling them to accelerate faster than conventional internal combustion engines.

Sunreef Yachts Eco envisions a more carbon neutral future for its catamarans. But apart from reducing emissions, the shipyard is also determined to find ways to significantly improve performance, range, and comfort onboard.

The Batteries on Sunreef’s Electric Catamarans

Sunreef Yachts Eco fully electric catamarans are equipped with custom engineered marine battery banks that offer prolonged battery life and more power despite compact size and optimized weight. With a density below 5.2kgs per kWh, these lithium-ion battery packs are recognized as 30 percent lighter than standard battery systems used worldwide. The reduced weight of the battery accounts for lesser drag, which translates to reduced energy being consumed by propulsion.

Additionally, the battery size is also smaller, leaving more room in the hulls to expand on living space. The ability to charge the batteries of this electric catamaran in harbors across the world, regardless of the voltage, adds a unique level of versatility and convenience for cruising.

It is important to note that Sunreef Yachts Eco equips each model within its range with custom marine lithium battery banks, scaling between 400 to 700V with pack sizes extending up to 1MW. Their capacity allows for nearly two days of air conditioning and house appliances use. These are fast charging, long-lasting batteries with a lifespan of up to 10 years; but even after years of service, 80 percent of the original capacity is maintained.

The Utilization of Renewable Energy on Yachts

Energy regeneration onboard an electric catamaran allows them to have an unlimited range without relying on external fuel sources, making them fully self-sustaining. Installing a clean green energy production to the catamaran’s existing battery pack makes it far easier to run the essential electric components onboard.

Renewable energy produces no GHG (greenhouse gas) emissions despite powering the world’s growing fleet of electric catamarans. To protect the oceans, here are the three major renewable energy types that can be harnessed onboard an electric catamaran:

1.  Solar Power 

The utilization of solar energy on electric catamarans has proven to be a significant step in decreasing the consumption of environmentally damaging fossil fuels such as gasoline. Sunreef Yachts Eco has successfully produced its in-house engineered, patent pending technology, solar panels that can be fully integrated into the composite bodywork of the electric catamaran. The energy produced is stored in lithium-ion batteries.

These are the industry’s lightest solar panels, that can be mounted on the superstructure, hull, or mast, for maximum power generation. In general, multihulls offer a more stable platform for accommodating a large solar array in comparison to monohulls.

2.  Marine Wind Turbines

Marine wind turbines (also known as wind generators or wind chargers) are mounted atop catamarans to maximize the conversion of kinetic energy of air in motion to electricity. This in turn keeps the battery banks charged in the absence of solar power; hence playing a vital role in the energy mix of electric catamarans.

It is generally a stable source of power throughout the day, regardless of whether the vessel is docked or under navigation. That being the case, the more wind pressure the catamaran encounters, the more power the turbines produce. Overall, wind turbines significantly reduce operational costs by minimizing fuel consumption.

3.  Hydro Generation 

Hydro generation allows you to create power whilst sailing in an electric catamaran. Simply put, harvesting the momentum of waves converts kinetic energy into electrical energy, which can later be fed into batteries to supply electricity to the ship.

Sunreef Yachts Eco redesigned their sailing catamarans to draw power from the energy of waves rather than fossil fuels. Because regeneration can even come from the free spinning of propellers when the boat is under sail, it proves to be a viable method for procuring clean, green energy. Additionally, it has proven to be highly efficient on electric catamarans produced by the shipyard as the electric power can be recovered from two engines.

How Innovative is Sunreef Yachts Eco?

During recent years, the Polish shipyard , Sunreef Yachts Eco has grown increasingly aware of the urgency of protecting the environment. Our research and development team has launched ground-breaking inventions in the yachting industry with greener tech, efficient design, and cleaner manufacturing processes.

Air Conditioning

For starters, electric catamarans from Sunreef Yachts Eco are the only ones to boast an energy-saving, gas-based air conditioning system, providing notable energy efficiency for a sustainable yachting experience.

This system consumes 70 percent less energy than the standard air conditioning system. Not only is it capable of running on batteries throughout the night to guarantee a peaceful sleep onboard, but also provides top-notch humidity control in tropical regions.

Smart Water Management

Because freshwater generation is crucial for sustainable cruising, Sunreef Yachts Eco installs advanced water purification systems and highly efficient watermakers onboard electric catamarans. This guarantees unlimited access to clean water which reduces the need for plastic bottles onboard.

Another ongoing project by the research and development team at Sunreef Yachts Eco is the Zero Cat , a 90 feet catamaran with unique clean, green power generation capabilities.  This superyacht ’s fuel cell system will convert methanol to hydrogen onboard for zero-emissions cruising.

Sunreef Yachts Eco also aims to be the first shipyard to incorporate hydrogen on its electric catamarans as a substitute to conventional energy. Combining hydrogen power with electric propulsion would enable the 80 feet sailing catamaran to achieve unrivalled autonomy for eco-conscious cruising as it powers both onboard appliances and engines.

Future Plans

The idea encapsulated here is to continue making sailing more accessible for people around the world, but with minimal impact on seas and oceans. Sunreef Yachts Eco aims to commission 40 electric catamarans in 2024 that embrace latest propulsion technologies such as electric motors, advanced lithium-ion battery chemistries, and regeneration capabilities that rely heavily on renewable sources of energy to help protect the planet.

If there’s one shipyard cementing itself even further as a leading superyacht builder, it’s Rossinavi, with the recent launches of 59-metre explorer yacht Akula , 49.9-metre No Stress Two and 65.7-metre Alchemy , which took home the prestigious Motor Yacht of the Year at the World Superyacht Awards 2024.

Just when it seemed Rossinavi had reached its pinnacle, the shipyard stunned the global yachting industry by venturing into the catamaran market with the launch of what it calls its “most innovative project” to date. The 42.8-metre hybrid-electric catamaran named Seawolf X , previously known as Sea Cat, features cutting-edge innovations, such as solar panels and AI, a testament to Rossinavi's commitment to the environment through its BluE initiative, which launched in 2022.

BOAT sits down with Rossinavi’s COO, Federico Rossi, to unpack some of the superyacht’s standout features…

“This kind of propulsion philosophy works very well on multihull vessels,” Rossi explains. “Catamarans are very efficient when it comes to navigation as they can reach good speeds with little power. They are also very stable boats, so they rely less on stabilisation systems that use lots of battery power. The wider beam also allows more surface area for the solar panels.”

Nature-inspired design

The exterior of this "futuristic" catamaran is the work of Fulvio De Simoni Yacht Design , boasting a streamlined, low-profile silhouette reminiscent of a sports car. The design includes three distinct exterior living areas: a sociable cockpit centred around a pool, a spacious sundeck with areas for sunbathing and relaxation, and a bow area featuring a hidden pool that transforms into a home theatre.

The designer also incorporated solar panels, optimising surface area for energy recovery as part of the shipyard’s commitment to environmentally friendly features. The hull's efficiency was enhanced through lightweight solutions, including an anchor installation that met weight standards and improved the vessel's aesthetics.

Inside, the design draws inspiration from nature, evoking the sun, sea and sand. "We used natural materials and, when possible, natural colours, to achieve this," says Rossi.

Energy-efficient features

The model operates with three distinct “performance scenarios”. For one-day trips, the catamaran can cruise entirely in full electric mode. On multi-day voyages, she maintains electric mode for 90 per cent of the time. Even on transatlantic journeys, she manages to cruise in electric mode for 80 per cent of the time.

“When the owner is not on board, the vessel goes into ‘hibernation’ mode when only the fundamental systems on board are in use," Rossi notes. The hibernation mode activates when the catamaran is moored, minimising consumption and allowing the excess energy generated to be supplied back to the quay or a private property. Seawolf X produces enough energy to power an entire villa.

Additionally, the catamaran is equipped with two diesel generators capable of quickly recharging the batteries. She also features fast charging, meaning she can fully recharge at shore power within just five hours.

Embracing the power of artificial intelligence

The catamaran features an onboard artificial intelligence system known as Rossinavi AI, designed to enhance comfort and maximise the yacht’s environmental efficiency. The AI constantly monitors the vessel’s operations, acting like a brain that learns from observation and anticipates the needs of guests.

Rossinavi AI maintains continuous communication with the crew, advising them on how to adopt lower-impact behaviours and promoting conscious cruising. “For example, if the chef is cooking in the galley and there is laundry in the washing machine and dryer at the same time, the system picks up a peak in consumption and informs the crew,” Rossi says.

The AI software also monitors the battery pack, ensuring it remains within the optimal range of 20-80 per cent to prolong its lifespan. Additionally, it supervises and interacts with the crew to maintain efficient operations.

Looking ahead, Rossi envisions advancing AI capabilities in future Rossinavi models, with the potential for the system to alert guests when dolphins or other wildlife are nearby, ensuring they don't miss the chance to enjoy such sightings.
