Rossinavi Seawolf X Yachts for Sale

Seawolf X is the inaugural model from Italian shipyard Rossinavi’s Sea Cat series, a range of eco-conscious, high-autonomy cruising catamarans.

Said to be one of the most technically ambitious hybrid-electric catamarans in the global fleet, she measures 42.8 metres in length with a beam of 13.75 metres and a draught of just 1.85 metres, with 499 GT. Seawolf X features a modern exterior design by Fulvio De Simoni Yacht Design, with complementary interiors by New York-based Meyer Davis Studio and naval architecture by Rossi Engineering Design & Services. Unique to Seawolf X is her hybrid-electric propulsion system, managed by Videoworks AI software, which continuously optimises energy consumption across three operational modes: full electric for day passages, 90 percent electric for multi-day cruising, and 80 percent electric for transatlantic range, achieving up to 5,400 nautical miles at 8 knots. Integrated solar panels across the low-profile superstructure contribute to onboard generation, and a hibernation mode when at anchor reduces hotel load to a minimum, with the ability to return surplus energy to a shoreside grid or villa.

The clean and purposefully understated exterior design pairs well with the calm interiors, inspired by the 1 Hotel South Beach in Miami, which feature natural materials like stone, leather, and raffia throughout to create warm, textural spaces that strike a balance between sustainability and comfort. Key features onboard Seawolf X include a 100-square-metre main deck lounge that converts to an open-air cinema and a hidden pool in the bow. The Seawolf X accommodates up to 12 guests across five staterooms, including a main-deck owner’s suite, supported by seven to nine crew. She has a top speed of 12 knots and a cruising speed of 10 knots.

key features

AI-managed hybrid-electric propulsion: Videoworks software actively optimises power distribution across three distinct operational modes, enabling near-silent cruising and a transatlantic range of 5,400 nautical miles without conventional fuel dependency.
Hibernation mode with grid energy return: When at anchor, the yacht reduces to minimal power consumption and can feed surplus generated electricity back to a shoreside grid or connected property — a capability with no direct equivalent among superyachts of this size.
1.85-metre draught: The catamaran’s exceptionally shallow draught gives access to anchorages, reef systems, and protected marine environments that remain out of reach for most monohull superyachts of comparable guest capacity.
Meyer Davis Studio interiors: The use of stone, leather, and raffia throughout reflects a conscious departure from conventional interior materials, aligning the onboard aesthetic with Seawolf’s broader sustainability philosophy.
