ISA delivers Sea Raider X, a 67m flagship and the yard's largest
The yard's biggest, and a change of scale
Sea Raider X measures 67 metres, wears a black-painted steel hull under a silver aluminium superstructure, and spreads her layout across four decks plus a bilge deck. She was launched in Ancona on 8 May 2026 and has now been handed over after a summer of trials. In a yard history that runs back a quarter of a century, she is the largest yacht ISA has ever built.
The exterior lines are by Vallicelli Design Studio, the interior by Team for Design with Enrico Gobbi, and the naval architecture was drawn in-house. The accommodation runs to 14 guests in seven cabins, with a full-beam owner's suite set forward on the main deck; a crew of 13 plus the captain is housed in eight cabins.
A pool, a beach club and a side-launched tender
The social case for the boat sits aft. A 6.5-metre panoramic swimming pool anchors the main deck, and a beach club at the waterline carries a hammam, a bar and a gym. Opening side platforms fold out to widen the walkable surface once she is at anchor, the Gran Turismo line's stock move for turning hull volume into deck.
Stowage is built around a main tender of more than 7.5 metres, launched through a side hatch rather than lifted off a deck. That keeps the top decks clear for guests and reflects the choice, on a boat this size, to treat the tender as a garage problem rather than a crane one.
Why the owner cares
ISA sits inside Palumbo Superyachts, a group better known for refit yards and production-rooted builds than for one-off flagships. Sea Raider X is the evidence that it can deliver a full-custom 67-metre in steel, a different survey, flag and resale pool than the composite boats a tier down. For anyone speccing an Italian yacht above 60 metres, that is a new name on the shortlist.
The Gran Turismo badge traces back to the 66-metre Okto, still one of ISA's most copied profiles. Sea Raider X carries it up a size and into heavier displacement, which is the real signal here: the line that made the yard's reputation now tops out higher than it ever has.
