Rossinavi unveils 43m hybrid-electric catamaran concept Solsea

Italian shipyard Rossinavi has unveiled a new, 43-metre catamaran concept known as Solsea. The yacht would be capable of cruising in full-electric mode for 80 per cent of a transatlantic crossing, following in the footsteps of Rossinavi's first multihull project, the 42.8-metre Seawolf X.

Solsea has been designed in collaboration with world-renowned product designer Yves Béhar, who is the keynote speaker at this year's Superyacht Design Festival. It is Béhar's first foray into yacht design.

"As an active ocean explorer for the last 40 years, I have sailed, kited and surfed across all continents, contributing to ocean preservation initiatives," explained Béhar. "My deep respect for the oceans informs every aspect of the design."

This includes a battery and solar panel system said to reduce operating costs by 80 per cent while cruising and by 100 per cent while wintering. Recycled ocean plastic has also been used for certain manufacturing projects, including furniture on board.

The catamaran is said to offer numerous living configurations, though the owner's suite is proposed as full-beam and has been designed with an integrated office, living space and private deck connecting both hulls. The dining area has been envisioned with a sea-inspired ceramic chandelier and custom dining chairs, while circular cork flooring by Amorim features throughout as a green-minded and comfortable alternative to hardwoods.

The two hulls posed a challenge for the shipyard - this area of a catamaran can often look "visually cluttered" and lack adequate space for a beach club. The solution is a full-width hydraulic rear door that seals the boat and stairs when Solsea is in transit. When stationary, the door converts into a platform for watersports and other sea activities. 

Another interesting innovation sees the pool cover serve as both shade and a solar surface, moving up when the boat is stationary and down while she is cruising.

The sundecks are flexible, capable of multiple dining and lounging configurations, though the top deck features integrated sun lounge seats and a continuous wood bar that leads to a "viewing lounge". According to the shipyard, all amenities and controls would also be accessible to the owner via an app.

"Solsea was conceived with active owners in mind – those who are passionate about exploring the seas, participating in ocean sports, and undertaking long-distance crossings without refueling," concluded Béhar. "She is a return to a simpler, more respectful way to enjoy the ocean." 

According to BOATPro, Seawolf X was officially delivered to her owner in August 2024. She then went on to debut at this year's Monaco Yacht Show, where her interiors were revealed for the very first time.
