43m Rossinavi catamaran Seawolf X newly listed for sale under JCA

The 42.8-metre Rossinavi catamaran Seawolf X has been listed for sale under a joint central agency with Brandon Kummer from Kitson Yachts and Will Christie and Felix Sowerbutts from Christie Yachts.

Recently delivered in 2024, the yacht has a low-profile exterior penned by Fulvio De Simoni Yacht Design and naval architecture developed by Rossi Engineering Design & Services. Inside, an interior by Meyer Davis exudes "subtle New York influence" and is "inspired by sun, sea, and sand", according to her brokers. 

The catamaran has been impeccably maintained with only light charter use after she joined the charter fleet in June 2024 and is now offered for sale for the first time. BOAT  stepped on board for the February 2025 issue to uncover how the Viareggio-based shipyard gave the multihull platform a sharp makeover.

Stepping inside, the yacht's interiors evoke a sense of relaxed luxury through natural textures and eco-conscious choices. A 13.6-metre beam creates an internal volume of 499GT and accommodation is for 12 guests, including a 70-square-metre owner’s cabin located on the main deck forward, with the other four cabins located on the lower deck.

In terms of al fresco spaces, guests can benefit from three outdoor living spaces – comprising an aft cockpit with a pool flanked by sunpads, an expansive sundeck for lounging and a versatile bow area with a hidden pool that can transform into an open-air cinema.

Among her many features, the broker noted her hybrid-electric propulsion package, which reduces fuel consumption by up to 75 per cent, with a 1.5MW battery capacity delivering more than 24 hours of silent, vibration-free operation. Solar integration and lightweight construction further elevate her efficiency.

The yacht for sale has a top speed of 12 knots and a cruising speed of 10 knots.

Seawolf X is asking €36,900,000.
