The most revealing view of a large yacht is often from the water beside it. That is where a high-sided vessel can feel like a building you have left behind—or a place that remains connected to the sea. ISA's new Poseidon project makes that relationship central to its design.
Unveiled on October 21, 2026, the 86-metre proposal joins the ISA Large Yacht Collection. Enrico Gobbi's TEAM for Design is responsible for the exterior and interior, with naval architecture by ISA's technical department. This is a design announcement, rather than a completed yacht entering service.
A long profile with the accommodation set aft
The manufacturer's presentation shows a high, gently curved bow, a long foredeck and a superstructure positioned farther aft. Dark glazing and a slim interpretation of the ISA arch help visually connect the decks.
That creates an interesting tension. An 86-metre yacht has substantial volume to accommodate, yet the profile aims to stay light. The design's success will depend on how the outdoor terraces, railings and glazing work at human scale, not only how the vessel looks in a distant side view.
The beach club becomes a destination
ISA describes fold-down platforms, a sea-facing lounge and a wellness area with exercise and treatment spaces. The intention is to give the lower deck a role beyond boarding tenders or storing water toys.
Our reading of that arrangement is straightforward: guests are more likely to use a space when reaching it feels natural. A comfortable route from an interior lounge to a sheltered terrace can be more persuasive than another spectacular room reached through an awkward circulation path.
The same question applies to the relationship between guests and crew. Good service needs practical routes, places to put equipment and enough separation for the working day to continue without taking over the social spaces.
An owner's deck with its own outdoor rhythm
The proposal gives the owner an upper-deck suite with broad glazing and direct access to a forward pool area. Elsewhere, swimming and whirlpool spaces are distributed across the outdoor decks. Their different roles matter more than adding them together into a single pool-count headline.
A private terrace can support a quiet morning while other guests gather aft. That is a useful way to think about space on a yacht: several people should be able to enjoy different kinds of day at the same time. Privacy, shade and a comfortable place to sit can contribute as much as the size of a suite.
The project figures
| Item | ISA's published design |
|---|---|
| Length / beam | 86m / 12.8m |
| Construction | Steel hull, aluminium superstructure |
| Guest layouts | Six or seven cabins |
| Estimated range | About 5,000nm at 12 knots |
Those figures describe a proposed configuration. Range remains an estimate, and the public unveiling does not establish an individual build contract, delivery date or completed sea trials.
What makes Poseidon worth following
Poseidon belongs to a broader conversation about how large yachts are used. Our Feadship HIVE feature looks at another concept organized around life aboard. The useful comparison is how each design supports movement, privacy and social time, rather than a contest over length.
A future detailed specification would show how this proposal balances equipment, usable deck space and the demands of running a vessel at sea. Until then, Poseidon is an appealing statement of direction: a large yacht whose most memorable rooms may be the ones that open directly toward the water.
For a recent physical construction milestone rather than a concept unveiling, see the launch of Baglietto's ninth T52.
