Alva Yachts introduces Ocean Eco 90 all-electric catamaran

The 27M solar catamaran Ocean Eco 90 will be ready by the last quarter of 2021 and will have virtually unlimited range. Engineers and technicians at Alva Yachts are completing the molds for hull and superstructure.

Alva Yachts, German builder of electric catamarans and sail boats, has just announced the introduction of Ocean Eco 90 by Henndesign, a 27M multi-hull yacht with electric propulsion and (claimed) transatlantic range. The model fits the brand’s philosophy, which has sustainability at the heart of their yachts, both motor and sail. Differently to other electric boat brands, Alva Yachts models are designed specifically around electric propulsion, not retrofitted.

The (electric) journey has started

At the end of June 2020, the project of Ocean Eco 90 is completed and the technical specifications are defined. Construction has begun with the molds for the hull and the superstructure, while the yacht will touch the water by the last quarter of next year.

Ocean Eco 90 is a 27.50 meter long catamaran, with an impressive beam of 14 meters, with a hull made for the range of speed of green cruising, which is not about the thrill of speed but rather about enjoying the voyage. She will available with hybrid or fully electric powertrain. The design is by Milan and Holger Henn of the German Studio HENNDESIGN and the Hamburg based naval-engineering studio iYACHTS.

The superstructure is covered with over 200 square meters of solar panels, giving her a transatlantic range and, under right circumstances, a virtually unlimited autonomy, as the panels take the energy from the sun and store it in the battery packs that power the electric engines.

The hybrid version has two 250 kW electric drives and two 456 kW diesel engines, which also replace the conventional diesel generator.

In the full-electric variant, Ocean Eco 90 is pushed by two 500kW electric drives, connected to a 360 kW/h battery pack, which is powered by sun and generators. The solar panels reach 40 kWp (kiloWatt peak), allegedly much more than the best competitors, while the diesel generators produce 100 kW / DC each.

An even cleaner option is available: the diesel generators can be replaced by two hydrogen-fuel cell ones, and according to the shipyard this makes Ocean Eco 90 the first solar catamaran in this range without the additional aid of fossil fuels.

In both cases, the range in only-electric mode (generators off, power coming from the batteries) can reach 60 nautical miles, a good distance for exploring the most recessed and wild parts of the earth, even restricted marine reserves. All of this, in silence, enjoying the sound of the nature and without disturbing the sea fauna.

Ocean Eco 90 by Henndesign has been shortlisted for “Concept Under 40 Meters Award” in The International Yacht & Aviation Awards 2020.

While the process of construction is well underway, the first unit will be launched by the last quarter of 2021. Manufacturing is fully European, with hull and superstructure built in Antalya, Turkey, and interior and finishing made in Germany.
