Built by Italian shipyard ISA Yachts, Sea Raider X is part of the Gran Turismo 67M series and features exterior styling by Vallicelli Design, interiors by Enrico Gobbi, and naval architecture by Palumbo Superyachts. She is now the largest yacht in the builder's current fleet.
A new flagship refines the Gran Turismo identity
Sea Raider X represents the latest evolution of ISA Yachts' Gran Turismo philosophy, showcasing the sporty styling that defines the series with vast interior volume and owner-focused living spaces. Built on a displacement steel hull with an aluminium superstructure, the yacht features a 10.5-metre beam across four decks. Her striking profile is defined by a black hull contrasted against a silver superstructure, while Vallicelli Design's signature structural "frame" connects the wheelhouse roof to the aft bulwarks, creating the distinctive silhouette.
Resort-style aft deck centred around a 6.5m pool
The standout feature aboard the superyacht is the completely redesigned aft main deck, arranged around a 6.5-metre panoramic swimming pool. Fold-down side terraces significantly increase the usable deck area, while integrated staircases lead directly to the beach club below. A side-launch garage houses a tender measuring more than 7.5 metres, allowing the stern to transform into a full-beam leisure area complete with a hammam, gym and bar once the tender has been deployed.
Seven-cabin layout accommodates 14 guests
Accommodation onboard the motor yacht is arranged for up to 14 guests across seven cabins, including a full-beam owner's suite positioned forward on the main deck. Crew quarters provide accommodation for 13 crew members plus the captain across eight cabins, supporting both private cruising and extended voyages.
Twin MTU power for long-range cruising
Sea Raider X is powered by twin MTU 16V 4000 M65L diesel engines producing a combined 6,092hp, driving conventional twin-screw propellers. The 1,149GT yacht completed sea trials following her launch in May 2026 before being delivered in July. She is scheduled to make her world premiere at the Monaco Yacht Show 2026.
ISA Yachts continues expanding its custom fleet
According to YachtBuyer MarketWatch, ISA Yachts currently has 16 yachts in the order book. Leading the order book is the first ISA 100, due for delivery in 2029. She is a 100m superyacht, designed by Enrico Gobbi with in-house naval architecture; the 2,999GT flagship will feature a steel hull, aluminium superstructure, a private owner's deck, accommodation for 12 guests and a certified helideck, becoming the largest yacht ever built by the Italian shipyard. Another notable model is the ISA Classic 65, a semi-custom platform offering generous interior volume and long-range cruising capability.
