Lapping water where the sound of generators used to be. Fresh sea-air without the taint of diesel. Is this a glimpse of the future?
After turning heads at her MYS 2024 debut, the 43-metre (141-foot) hybrid-electric catamaran SEAWOLF X joins our charter fleet. Builder Rossinavi has combined cutting-edge technology with eco-conscious design in this innovative yacht that is redefining luxury at sea
SEAWOLF X features a state-of-the-art hybrid propulsion system that combines more than 200 solar panels, batteries, electric engines and diesel generators for exceptional, eco-conscious peformance. At its core is Rossinavi AI, a smart system designed to enhance efficiency and optimise operations, reinforcing the yacht’s commitment to eco-friendly innovation.
The exterior, crafted by Fulvio De Simoni Yacht Design, highlights a seamless blend of style and function. At the stern, a beach club is a haven for relaxation, complete with a sauna suite. Its custom-built transformer connects effortlessly to the quayside, but at anchor also drops quietly into the sea, providing easy access to all the water has to offer.
While at anchor, SEAWOLF X features a long list of toys to keep guests entertained. There’s a 5.35m Castoldi Jet 17 tender, two Seadoo Sparks, two Seabobs, two Cudajet underwater jetpacks, a Fliteboard efoil, six SCUBA sets, a pool, a platform, a jetski/Seabob dock, a Subwing, wakeboards, waterskis, donuts, inflatable kayaks and inflatable SUPs.
A recent addition is a SACS STRIDER 13m Chase Boat, which swiftly transports guests to the shore or enables exploration of secluded coves.
Water fun is great, but it’s on board where SEAWOLF X demonstrates her difference. On the main deck, the cockpit centres around a glass-fronted hot tub, flanked by cosy, living areas and a large dining table, ideal for alfresco gatherings. Above, the 130sqm sundeck invites guests to unwind with a mix of sunbathing zones, shaded seating and a spacious bar.
But it’s the quiet that really stands out.
Yes, you can charter SEAWOLF X with a cleaner conscience, given her sustainable pedigree, but it’s the silence that hits you. Imagine full-electric silent running where only the sound of the twin bows splitting the water breaks the peace. And at anchor she's just as gentle, with the rhythmic sound of the water lapping against her hulls. With all systems running, there's no generator noise, no fumes or gases. Just pure silence.
The owner’s vision was clear: to create a yacht that prioritises ecological responsibility without sacrificing luxury. SEAWOLF X delivers on this with its propulsion system, capable of producing around 35kW of power. Three performance modes allow flexibility: full electric for one-day trips; 90% electric for multi-day cruising; 80% electric for transatlantic journeys.
While docked, her Hibernation Mode minimises energy use, enabling the yacht to power a nearby home or quay. Two diesel generators ensure quick battery recharging, while shore power can fully recharge the yacht in just five hours.
Captain Sean Rysenbry says, "Spread across the two hulls she has deck widths comparable to a 70m yacht – whilst her shallow draft means she can slip into secluded bays other large yachts simply can’t reach. But what guests really love is the silent running and the stillness at anchor.”
Inside, New York studio Meyer Davis created an interior that’s both timeless and environmentally friendly. Natural materials like wire-brushed wood paneling and recycled wool rugs reflect the yacht’s eco-conscious ethos.
The main saloon spans 80sqm and offers panoramic views, with distinct spaces for relaxing and dining. The 70sqm owner’s suite on the main deck includes a marble bathroom, walk-in closet and private gym.
Will Meyer, Co-Founder of Meyer Davis, described the project as an opportunity to rethink yacht design: "SEAWOLF X allowed us to create something truly unique – a catamaran that’s elegant yet grounded in sustainability. Rossinavi’s commitment to thoughtful design inspired us to emphasise natural materials and carefully curated details.”
The lower deck – split between two hulls – ensures privacy for guests, with each hull featuring a double cabin and a twin cabin, with Pullman beds for flexibility.
SEAWOLF X is available for charter exclusively with Cecil Wright – offering a luxurious and sustainable way to explore the seas.
