Design & Construction
Designed around a catamaran aluminium hull and superstructure she features a 13.75m beam and a 1.85m draft. The yacht has an internal volume of 499 GT (Gross Tonnes).
The yacht was designed and constructed in compliance with the Lloyds Register technical standards. Launched in May 2024 this yacht undertook sea trials over the following months. She was delivered to her owners in August 2024.
Exterior Design
Seawolf X looks unlike almost anything else in the 40m market. Designed by Fulvio De Simoni Yacht Design, the 42.8m (140.4ft) hybrid catamaran trades the towering profile of a traditional superyacht for something far lower, sleeker, and more athletic. The silhouette has the stance of a performance coupé on the water, with dark glazing bands, sculpted hull sides, and a flowing roofline that almost appears to hover above the decks.
The multi-hull platform shapes nearly every exterior space on board. With a beam of 13.8m (45.3ft), the yacht gains enormous deck areas and remarkable stability without the need for active stabilisers. That width becomes most obvious in the aft cockpit, where mirrored lounge areas frame a central pool and create one of the yacht’s main social spaces. The layout feels open and relaxed, with broad walkways, deep overhang protection, and direct access to the water.
At the stern, the catamaran configuration creates a raised central section between the hulls that doubles as a diving platform and boarding area. The starboard hull integrates a dedicated spa and sauna space directly beside the swim platform, so guests moving between water toys, swimming, and relaxation areas rarely need to head back inside.
The sundeck takes a different approach to most explorer-style yachts. Instead of formal dining dominating the deck, the space focuses on lounging and social interaction. Large sunpads sit aft beneath open skies while a raised central bar creates the focal point of the deck. Solar panels integrated into the hardtop generate up to 16kW of power and form part of the yacht’s overall energy recovery system without compromising guest areas.
Forward, the bow becomes one of the yacht’s cleverest spaces. A hidden pool rises from beneath the deck and transforms the area into a private lounge with wraparound seating, glass balustrades, integrated lighting, and a drop-down cinema screen. When closed, the area returns to a clean uninterrupted foredeck profile.
The Oyster Grey hull, dark grey superstructure, and black pinstripe detailing give Seawolf X a restrained, technical appearance that suits the yacht’s hybrid identity. Aluminium construction for both hull and superstructure helps reduce weight and improve efficiency, while the teak deck surfaces soften the otherwise architectural look.
Interior Design
Seawolf X marks the first superyacht project from New York studio Meyer Davis, and the interior carries far more influence from high-end residential and boutique hospitality design than traditional yacht styling. Inspired partly by the studio’s work at 1 Hotel South Beach in Miami, the spaces feel calm, tactile, and intentionally understated.
The sheer beam of the catamaran platform transforms the main saloon. At 13.8m (45.3ft) wide overall, the yacht gains interior volume more commonly associated with significantly larger monohulls. Instead of placing the dining area directly behind the lounge, Meyer Davis positions the two spaces side-by-side. The arrangement feels more sociable and open, with lounging, dining, and entertainment all visually connected while still maintaining their own identities.
Materials play a huge role in the atmosphere on board. Oak joinery, textured fabrics, wool rugs made from recycled materials, leather detailing, raffia accents, and locally sourced stone replace the glossy lacquers often found aboard modern superyachts. The result feels warm and relaxed rather than formal.
Large sections of glazing pull natural light deep into the yacht, while skylights in key areas strengthen the connection with the sea and sky outside. Throughout the yacht, the design avoids reflective surfaces in favour of matte finishes and tactile textures that soften the spaces visually and acoustically.
Details also feel carefully thought through for life on board. Lighting responds automatically to guest movement, blinds can close themselves to reduce heat load and air conditioning demand, and the yacht’s AI-driven management system constantly adjusts onboard systems to improve efficiency in the background.
Accommodation
Seawolf X accommodates up to eight guests across four suites, with a layout designed to work equally well for private ownership and charter use.
The standout space is the owner’s suite on the main deck forward. Covering approximately 69m² (750ft²), it occupies the full beam of the yacht and functions almost as a private apartment within the vessel. A skylight above the bed floods the sleeping area with natural light, while full-height glazing and side observation lounges maintain constant views of the sea.
The suite also integrates a private office, large dressing room, marble-finished bathroom with twin sinks carved from a single slab of stone, and an enclosed gym area. Forward-facing lounge spaces built into the hull sides create quiet private corners directly above the waterline.
Guest accommodation sits within the hulls on the lower deck. The layout includes two double cabins and one flexible cabin that can operate either as a twin or double arrangement. Another twin cabin also includes a Pullman berth for additional flexibility during charter operations. Thanks to the catamaran’s beam and freeboard, the cabins gain unusually good headroom and large hull-side windows that bring in far more natural light than many conventional lower-deck cabins.
Each guest suite follows the same soft contemporary styling seen throughout the yacht, with textured fabrics, warm timber finishes, integrated lighting, and ensuite bathrooms finished with stone and matte surfaces.
Crew accommodation supports up to nine crew members across four cabins, including a private captain’s cabin. The multi-hull arrangement benefits the crew areas too, creating a notably large crew mess and generous service spaces for a yacht of this length.
Performance & Capabilities
Seawolf X has one of the most unusual propulsion systems currently fitted to a modern superyacht. Instead of relying on conventional main diesel engines, the yacht uses twin electric propulsion motors powered through a large-scale hybrid energy system built around 1.5mW of battery storage.
Two diesel generators recharge the batteries and supply onboard systems, while integrated solar panels across the superstructure contribute additional renewable energy generation. The yacht can also recharge from shore power in around 5 hours.
The hybrid system allows Seawolf X to operate in several different modes depending on the voyage profile. For shorter day trips, the yacht can run entirely in electric mode. During extended cruising, electric operation can account for roughly 90% of usage, while even transatlantic passages can reportedly be completed with the yacht operating electrically for around 80% of the crossing.
At 8 knots, the yacht can run silently on battery power alone for around 6 hours, while hotel systems can remain active at anchor for 10-15 hours without generators running. Without large diesel engines, stabilisers, or continuously running generators, the yacht eliminates much of the vibration and background mechanical noise associated with traditional superyachts.
Inside the engine rooms, the advantages of the hybrid arrangement become obvious. Without large main engines dominating the machinery spaces, access and working room improve dramatically. The electric motors themselves contain far fewer moving parts than conventional diesel propulsion systems, simplifying maintenance and reducing mechanical complexity.
An AI-assisted power management system constantly monitors energy usage across the yacht, automatically adjusting systems to reduce waste, and lower overall power demand. Even at anchor, Seawolf X can enter a low-consumption hibernation mode and potentially feed excess stored power back into shore-side systems or private properties.
