Developed by Enrico Gobbi's TEAM for Design, the new superyacht concept joins the Amarcord 82, Amarcord 86 and Essence 82 in the growing range of large custom yachts from the Italian builder.
ISA Poseidon 86M Features Sweeping Bow and Sports Car-Inspired Design
Measuring 86m in length with a 12.8m beam, Poseidon features exterior and interior design by Enrico Gobbi - TEAM for Design, with naval architecture developed in-house by ISA Yachts.
Its profile is distinguished by a tall, gently curved bow and an elongated foredeck, with the superstructure positioned further aft. The arrangement gives the yacht a particularly long forward section, while extensive glazing runs along the main accommodation decks.
The exterior design alternates taut surfaces with softer geometries, creating a continuous interplay of volumes that brings movement to the overall architecture."

The builder's signature arch has also been redesigned with a slimmer profile, reducing its visual impact without obstructing views from inside. Sculpted air intakes and angular superstructure detailing draw inspiration from sports cars, an influence carried through to the aft decks and uppermost lounge.
The stern is particularly distinctive, with several tiers of open terraces, low bulwarks and a glazed swimming pool forming part of the motor yacht's aft profile.
Inside ISA Poseidon 86M's Three Pools and Beach Club
One of Poseidon's main features is its three-pool arrangement, with separate swimming and relaxation areas distributed across the main deck, owner's deck and lower-deck beach club. The main deck aft centers on a large T-shaped swimming pool, with a dedicated whirlpool section and a larger area for swimming. Its glazed structure is framed by a sculpted surround inspired by a sports car spoiler, while underwater lighting is designed to emphasize the pool's appearance after dark.
Below, the beach club opens directly onto the water through fold-down side platforms. A sea-facing lounge, bar and glass-sided whirlpool occupy the aft section, with two additional balconies providing further outdoor access.
A passageway leads forward to a dedicated wellness area with a gym, sauna, steam room and treatment facilities, including massage spaces. The aft decks are arranged across several levels, with progressively slimmer deck edges intended to preserve views towards the sea.
ISA Poseidon 86M Owner's Suite Features Private Pool and Helipad
The upper deck is reserved entirely for the owner, with a private suite surrounded by 360-degree glazing. Accommodation includes a study, dressing room and bathroom with a double shower and bathtub.
Directly forward, a long swimming pool occupies the open deck, with sunbathing areas positioned alongside. The forward location provides privacy from the yacht's principal guest spaces, while the same area can also serve as a touch-and-go helipad.
Aft of the owner's accommodation, an indoor lounge opens onto an exterior entertainment area with a dining table for 14 guests. Further above, the bridge deck accommodates a panoramic sky lounge and Jacuzzi. Its roof follows a low, curved profile inspired by the shape of a sports car cockpit, allowing the additional lounge to sit within the yacht's streamlined superstructure.
Poseidon offers six or seven cabins accommodating 12 or 14 guests, with 18 crew housed in 10 cabins. Designed by Enrico Gobbi - TEAM for Design, the interior features a main deck salon with lounge seating, a cinema and formal dining area, alongside extensive glazing and separate crew access routes. Full details of the interior finishes have yet to be revealed.
17-Knot Top Speed and 5,000nm Range
Poseidon has been developed with a high-strength steel hull and aluminum superstructure, with a full-load draft of 3.6m. Twin MTU 16V4000M63L engines, each rated at 2,240kW (approximately 3,004hp), are specified to deliver a maximum speed of 17 knots and a cruising speed of 14 knots. The projected range is approximately 5,000 nautical miles at 12 knots.
Tender storage is divided between a forward garage for a rescue tender and water toys, and a second garage amidships capable of accommodating a tender measuring up to 9.5m. The larger tender garage is offered as an alternative to the gym.
ISA Poseidon Becomes Fourth Large Yacht Collection Project
According to YachtBuyer MarketWatch, the largest yacht database in the world, Poseidon follows three other superyacht concepts introduced by ISA Yachts during 2026, as the Ancona-based builder expands its offering in the 80m-plus sector. The collection began with the 82m Amarcord, followed by the larger 86m Amarcord. The 82m Essence subsequently became the third design before the introduction of Poseidon.
A 100m GranTurismo superyacht is also under construction and is expected to become ISA's new flagship. The builder operates under Palumbo Superyachts alongside Columbus Yachts, Mondomarine and EXTRA Yachts.
