Built in steel and aluminum, the four-deck yacht marks the latest evolution of ISA Yachts’ long-running Gran Turismo series, pairing a dark, high-contrast exterior profile with a reworked beach club and aft deck arrangement focused on outdoor living.
Sea Raider X Becomes New ISA Flagship
The launch took place at ISA Yachts’ facilities in Ancona, with Sea Raider X becoming the largest yacht currently delivered under the Gran Turismo line. The project was developed by Italian studio Vallicelli Design, responsible for the exterior styling, while interiors were designed by Team for Design - Enrico Gobbi. Naval architecture was completed in-house by ISA Yachts, part of the Palumbo Superyachts group.
Measuring 67 meters in length, the yacht features a black-painted steel hull paired with a silver aluminum superstructure, creating a sharp visual contrast that emphasizes the yacht’s low, elongated profile. According to the yard, the design continues the styling direction established by earlier Gran Turismo models while introducing a more sculpted and geometric aft section.
A More Aggressive Take on Gran Turismo Design
One of the defining visual features is the contrast between the softer deck lines and the angular architecture around the stern and sundeck. The superstructure profile is organized around a prominent framing element extending from the wheelhouse hardtop toward the aft bulwarks, a styling cue carried across the Gran Turismo range.
The side profile of the superstructure develops around a “frame” element connecting the wheelhouse hardtop to the aft bulwark of the main deck, lending the yacht a strong sense of dynamism and recalling the distinctive styling cues of the Gran Turismo family line."

The aft sections also introduce one of the motor yacht’s main layout developments. On the main deck, a 6.5-meter panoramic swimming pool sits at the center of a large open-air lounge area. Fold-down side platforms expand the usable deck space around the pool, creating a broader waterside social area connected directly to the beach club below via integrated staircases.
Expanding the Yacht’s Waterside Footprint
Sea Raider X places significant emphasis on its lower aft guest areas, with the beach club designed to transform once the main tender has been deployed. The tender garage houses a vessel measuring more than 7.5 meters in length, launched through a side hatch on the lower deck.
Once cleared, the covered aft section opens into a full-beam beach club arrangement that effectively doubles the usable space in this area. The beach club itself incorporates a hammam, bar, and gym, continuing the recent industry shift toward larger wellness-focused lower deck layouts.
The arrangement also improves circulation between the swim platform, beach club, and aft lounge areas, creating a more connected waterside setup across multiple levels of the yacht.
Seven Cabins Across a Multi-Deck Layout
Guest accommodations are arranged for up to 14 guests across seven cabins, including a forward-facing owner’s suite positioned on the main deck. Crew accommodations provide space for 13 crew members plus the captain across eight cabins.
The yacht’s internal layout spans four decks plus a bilge deck, giving Sea Raider X the internal volume expected of a modern steel and aluminum displacement superyacht in this size category.
Broader Growth Across the ISA Portfolio
According to YachtBuyer MarketWatch, the largest yacht database in the world, ISA Yachts’ recent activity places Sea Raider X within a wider period of expansion across several size segments. In February 2026, the yard laid the keel for superyacht K3, an ISA Gran Turismo 68M superyacht scheduled for delivery in 2028, with exterior design by Vallicelli Design and interiors by Team for Design - Enrico Gobbi. The project follows a similar long-range, steel-and-aluminum direction, with accommodation for 14 guests and a projected range of around 5,000 nautical miles.
ISA has also recently introduced its Timeless range, developed with Luca Dini - Design & Architecture and spanning 42m to 82m models, with the ISA Timeless 52 serving as the first detailed platform. At the performance end of the portfolio, construction has started on the second ISA Viper 130, a 39m on-spec yacht due in 2028.
