Rossinavi Seawolf X, artificial intelligence at the service of energy saving
The new 42-meter hybrid propulsion yacht stands out for its integrated artificial intelligence that monitors fuel consumption and suggests virtuous habits. A project by Fulvio De Simoni Yacht Design in collaboration with Meyer Davis interior design studio.

At 42,75 meters long and 13,74 meters wide, Rossinavi's Seawolf X catamaran embraces the shipyard's new BluE vision for hybrid-electric yachts to reduce CO2 emissions. Seawolf X's hybrid system allows for three operating modes: for day trips, it can run in full electric mode for 100 percent of the time; for multi-day trips, it can sail in electric mode for 90 percent of the time, while for ocean crossings, it can sail in electric mode for 80 percent of the time. Hibernation mode, which activates when the catamaran is moored, reduces consumption to a minimum, and the energy collected through the solar panels can be returned to the dock or to private property (if connected to the yacht's grid). It is equipped with a pair of diesel generators to recharge the batteries, while using the grid takes just five hours. Seawolf X is also powered by the Rossinavi AI artificial intelligence system, designed to enhance comfort and maximize the yacht's environmental potential. The AI monitors the vessel's operations, acting as an intelligent system that learns from observation and anticipates guests' needs. The AI interacts with crew members, offering guidance on sustainable practices and encouraging low-impact behavior. It also monitors the batteries, ensuring they remain within the optimal charge range between 20% and 80%, thus helping to extend their lifespan.
Federico Rossi, COO of Rossinavi, said: “This is a first step toward a new vision of recreational boating. Until now, the world of catamarans has been divided between sail and motor, but now we have succeeded in developing a hybrid-electric model that introduces a new style even for vessels of this size. Furthermore, we have installed an artificial intelligence system on board to monitor fuel consumption. Thanks to machine learning, it will be self-learning, undoubtedly surprising us in the future. This represents a further push by Rossinavi to create an innovative trend and to highlight its construction and technical expertise. A vision that not only addresses the challenges of the present but also anticipates the needs of the future.”
The 80 square meter main salon is divided into a lounge and dining area, offering a versatile space ideal for hosting meetings or enjoying moments of relaxation. The 70 square meter master stateroom is located on the main deck and features a skylight to increase natural light, a walk-in closet, and a private gym. The stateroom also offers direct access to a mooring area on deck that can be transformed into a private terrace. The 130 square meter sundeck features a sunpad, a shaded seating area, and a bar. It also includes a screen for onboard infotainment, integrated with the AI system. The sundeck is equipped with 202 solar panels covering a surface area of 156 square meters. The lower deck is divided into two symmetrical hulls furnished with a double cabin and a twin cabin with pull-down beds.
Seawolf X boasts architecture by Fulvio De Simoni Yacht Design, featuring a low, sleek profile and a partially recessed helm station, allowing guests on the sundeck maximum openness and visibility forward. The designer explained: “We set out to imagine the boat of the future, one that would break free from traditional constraints while remaining fully buildable. Our goal was to integrate cutting-edge technologies that minimize environmental impact without compromising innovation.” Designed by Will Meyer and Gray Davis, the interior design is distinguished by brushed wood paneling, woven raffia wall coverings, and recycled wool carpets. These elements reflect the yacht's commitment to eco-luxury, while Scandinavian influences and modern warmth create a residential atmosphere in keeping with the owner's aesthetic sensibilities.
