Second solar cat sold

ALVA Yachts, the German builder of electric solar catamarans and sail boats, has sold its second OCEAN ECO 90 Open.

01 December 2022


The ALVA OCEAN ECO 90 Open is a 27.5-metre multihull yacht with electric propulsion and transatlantic range.

The largest of its catamarans, the first OCEAN ECO 90 is due to be on the water at the end of 2023, currently with the first hull complete and awaiting its interior fit out. The second will be ready for the water at the end of 2024.

As with all ALVA catamarans, the OE 90 has been designed with responsible yachting at its core and fuses form and function together. Its expansive roof has been specifically conceived for its integrated solar panels, giving her a transatlantic range and virtually unlimited autonomy, as the panels take energy from the sun and store it in the battery packs that power the electric engines.

The OE 90 offers modern shapes, and a clear futuristic feel with classic colours and materials creating a well-rounded exterior design for forward-thinking owners.

The first OE 90 sold was its Explorer version offering an enclosed flybridge, carbon and stainless-steel reinforcement for the hull structure and many other modifications.


The main saloon doesn’t feature a helm station, while the huge enclosed upper bridge can be a large saloon/ skylounge or an owner’s cabin with a 360-degree view. It features an additional hot water heater and tropical air conditioning.

The second sale is the Open version of the OE 90, which boasts an open flybridge and helm station as well as a sky lounge, cocktail bar and jacuzzi on the top deck.

Both versions offer a large beach club, water-sports and entertaining areas, coupled with spacious above-deck living and entertaining zones that provide a modern ocean lifestyle.

The full-electric OE 90 is powered by two 500 kW electric motors, connected to a 140–360 kWh battery pack, which is powered by sun from 200 m2 of solar panelling and generators.

Access to the water is easy from her twin bathing platforms. From bow to stern, this remarkable 14-metre beamed catamaran offers impressive space, modern style and stable sailing.

The aft deck is appointed with plush U-shaped seating for eight guests, perfect for al fresco dining or sunset cocktails. From here, guests can access the enclosed saloon and spectacular entertaining area.

The generous galley comes complete with full-size fridge-freezer and features a large separate island with bar and stools. To starboard, a large dining table for 10 provides the perfect spot for family and friends to enjoy a meal.

A large L-shaped observation seating area accompanies the helm station with commanding views forward. Mid-ship two side companionways lead to the lower deck and accommodation.

The generous master suite boasts spacious lounge seating areas either side of the bed, a private study and walk-in wardrobe leading to a large ensuite with dual sinks. The starboard side is complete with a twin guest room with ensuite. Further guest accommodation is located within the portside hull and features two ensuite double rooms and two single rooms, perfect for staff.

The foredeck provides another social space with two separate seating arrangements plus oversized sunbeds, complete with ample storage and refrigeration options.

Its unique main deck, penthouse-style salon, and luxurious staterooms offer a new-found design direction and material selection providing elegant interiors to enchant any owner. The layering of textural elements and the mix of furnishings and fabrics feels timeless with a modern twist that exudes quality, simplicity, and sophistication.

Milan Henn, Head of Design at ALVA Yachts said, “The OCEAN ECO 90 is our flagship vessel and is the mother to our range which includes the OCEAN ECO Cruise 50, 60, 78 and 90.

“We’re delighted to have sold the second one in production – it demonstrates its popularity for the lifestyle we imagine our owners to lead.”

The OE 90 breaks new ground in yacht design and cruising efficiency and is truly one of the finest examples of modern-day superyacht building. Its vast open outdoor space, large open flybridge and expansive saloon have the wow factor. It’s 100-percent electric, self-sufficient and fuel cell ready.”

ALVA Yachts is bringing yachting into a new era with electrified solar catamarans and sailing yachts that combine self-sufficient, long-range cruising capabilities and class-leading design, delivering the best boats for forward-thinking explorers.
