Set for 2029 delivery, the 100-meter vessel will eclipse the shipyard’s current flagship Okto by more than 30 meters, marking a major new chapter for the Italian builder.

Palumbo described the contract as “a fundamental step for the world of Giga Yachts,” underlining the shipyard’s long-term vision of uniting advanced engineering with distinctive design at large scale. For Gobbi, the 100-meter platform presents an opportunity to evolve the ISA identity, building on the brand’s established styling language while reshaping it for the upper end of the market.
Design Vision
The ISA 100m Custom yacht has been conceived as a “grand coupé of the sea,” with a streamlined, automotive-inspired profile and an assertive bow. The yacht carries forward the yard’s iconic ISA arch, here reinterpreted with a new dynamic strength than seen on earlier models such as the 65-meter motor yacht S5.
The profile of the new yacht emphasizes both form and function, with fluid lines improving balance and visibility at sea. The motor yacht is built with a steel hull and aluminum superstructure, the vessel is projected to reach a gross tonnage of 2,999 GT.
Interior Arrangement
Accommodation on board the superyacht will be arranged across six double staterooms, including a VIP suite with its own lounge. The owner’s suite will occupy an entire dedicated deck, ensuring privacy and space for personal use. Service will be provided by a complement of 31 crew, supporting high standards of operation.
Among the notable features is a certified helideck, expanding options for embarkation and long-range travel.
Technical Profile
Propulsion will come from twin MTU 16V 4000 M65L engines producing 2,560 kW each, delivering a top speed of 17 knots. The setup has been selected to balance reliable performance with efficiency, supporting extended voyages at sea.
Context in the ISA Fleet
Once delivered, the ISA 100m Custom will become the largest project in Palumbo Superyachts’ portfolio and a significant advance beyond ISA’s existing flagship, the 66.4-meter Okto.
According to YachtBuyer Market Watch, the world's largest yacht database, ISA Yachts currently has 12 yachts on order or under construction, spanning from 38 meters to the new 100-meter flagship. This includes the 80-meter project scheduled for 2027 delivery, with the ISA Continental 80 Yacht listed for sale with TWW yachts.
Looking Ahead
For Palumbo Superyachts, the contract marks a decisive step into the giga-yacht sector. The ISA 100m Custom will expand the yard’s capabilities at the very top of the market, with delivery in 2029 set to establish a new benchmark within the ISA fleet.
