Sunreef is at the forefront of eco boating with its latest innovations in hybrid and electric propulsion, photovoltaic panels integrated into the hull, and sustainable design. The recently launched Sunreef 80 Power Eco is a prime example of their commitment to sustainability.
Sunreef currently employs 2,400 people and is expanding with a new 65,000 sq.m site in Ras Al Khaimah (UAE). Founded in Gdansk, Poland, over 20 years ago, Sunreef specializes in large, luxury catamarans. Initially focusing on sail-only models, they have expanded to motor-only and custom-made superyachts. Sunreef has been a pioneer in hydrofoil, energy conservation, and hydrogen propulsion, establishing itself as a leader in high-end multihulls.
The latest model, the Sunreef 80 Power Eco, combines electric propulsion and integrated photovoltaic panels for a sustainable and visually appealing yacht. The upcoming Ultima series will feature hybrid sport motor catamarans ranging from 14 to 27 meters, built at the new Ras Al Khaimah site.
Sunreef’s Zero Cat Project
Sunreef’s next major innovation is the Zero Cat, a sailing catamaran with hydrogen-powered electric motors. This yacht will use a hydrogen generator to produce hydrogen from methanol on board, powered by the yacht’s solar power system. The fuel cell system will generate clean energy with zero emissions for both propulsion and hotel loads. The use of methanol addresses regulatory issues and storage challenges associated with hydrogen. Sunreef plans to launch the Zero Cat by the end of the year.
With Nicolas Lapp, Sunreef Yachts CTO and Co-Founder, we talk about the latest developments at Sunreef
What are the main technical features of this technology?
Sunreef Yachts develops in-house solar panels with a composite-integrated solar power system. These highly efficient cells achieve a peak performance of 24%. The panels are extremely flexible, shock-resistant, and can be replaced if needed. They can be strategically placed on any yacht surface, maximizing energy generation.
What about its performance?
An 80 Sunreef Power can feature up to 200 sq.m of solar panels (weighing around 360 kg) that deliver 40 kW peak per hour. This efficient setup allows the yacht to operate solely on renewable energy, especially at reduced cruising speeds, matching the output of two generators weighing around 800 kg. Sunreef Yachts leads in advanced solar yacht solutions to achieve the highest efficiency in the market.
These panels are particularly lightweight and impact and abrasion-resistant, right?
Yes, with a thickness below 1 mm and weighing approximately 1.8 kg per sq.m, they are significantly lighter than average solar panels (8-15 kg per sq.m). They have high resistance to shock and abrasion, allowing them to be used on any surface, including hull sides.
Why did you build the hydrogen-powered boat Zero Cat?
The owner of Zero Cat requested a boat with hydrogen propulsion. The project involved replacing the diesel genset with a hydrogen fuel cell while ensuring compatibility with existing equipment.
How did the decision to expand come about?
Sunreef Yachts is expanding its capacity with a new facility in Ras Al Khaimah, UAE, in partnership with RAK Maritime City.
This state-of-the-art facility spans 65,000 sq.m and will incorporate the latest technologies in luxury yacht building, meeting the highest standards of sustainability and energy efficiency. The grand opening is scheduled for February 2024, with the shipyard operational since the end of 2023.
What are the main features and strengths of the new site?
The new facility offers a comprehensive approach to yacht manufacturing with advanced workshops for painting, carpentry, upholstery, and stainless-steel work. It is equipped with state-of-the-art machinery and robotics, emphasizing sustainability.
How did you select the workforce?
The workforce selection began with Polish experts training the initial staff. Components manufactured in the UAE were shipped to Poland to enhance production at the Gdansk shipyard. The Ras Al Khaimah shipyard is recruiting nearly 100 individuals, including 30 experienced engineers from diverse global regions, led by a Managing Director with extensive marine industry experience.
Sunreef 80 Power Eco: The Future of Electric Catamarans
An electric catamaran measuring 23.8 m in length and 12 m in width, featuring about 200 sq.m of photovoltaic panels integrated into the hull and superstructure. It includes a 990 kWh battery bank.
Innovative Design and Performance
With the Sunreef 80 Power Eco, the Polish shipyard addresses the challenge of balancing luxury, performance, and energy conservation in modern boating.
Yacht with Wow Factor
The first unit of this 23.8 m long and 12 m wide catamaran debuted at the Cannes 2023 boat show. The second unit, Sól, featuring more powerful thrusters and a record-breaking battery bank, was showcased at the Fort Lauderdale boat show. The yacht’s standout feature is its 200 sq.m of photovoltaic panels seamlessly integrated into the hulls, bimini roof, windows, and flybridge structure, delivering 36 kWh peak power to support the onboard engines and hotel services.
Photovoltaic Panels and Battery Bank
Sunreef has revolutionized photovoltaic panels, turning them from unsightly technical elements into strategic components of both the energy system and yacht aesthetics. The design includes a pair of 360 kW e-motors and a 990 kWh battery bank on Sól, the largest installed on a boat under 24 m. These batteries are nearly 30% lighter than typical systems, allowing the yacht to sail up to 300 miles on electric power alone. The charging system adapts to any voltage available in global ports, supporting shore power from 100v to 450v. A hybrid version of the Sunreef 80 Power Eco is also planned.
Spacious and Luxurious Onboard
Sól offers 356 sq.m of space for guests, including four cabins (master and three doubles, all with ensuite facilities) and accommodations for four crew members. The large salon connects to the aft cockpit, which is protected by the flybridge and features a large dining table and forward lounge. Guests can access the aft platform with jet skis and water toys from the cockpit. The flybridge includes an outdoor command post, sunbathing area, bar, and dining area.
