Heesen Yachts has launched its latest full-custom superyacht, the 187-foot Project Setteesettanta, at the builder’s shipyard in Oss, the Netherlands. Built entirely in aluminum for repeat Heesen owners, the yacht is scheduled for delivery before the end of 2026 following sea trials later this summer.
At approximately 920 gross tons, Project Setteesettanta was designed as a long-range family cruising yacht with a relatively shallow 7-foot, 7-inch draft that allows access to destinations where deeper-draft yachts may be limited. Exterior styling comes from Omega Architects, while Cristiano Gatto Design handled the custom interior and also represented the owners throughout the construction process.
The yacht spans four decks, highlighted by a private owner’s deck that includes the forward-facing master stateroom with 180-degree views and direct access to an expansive private terrace. The terrace, measuring nearly 2,150 square feet, also serves as a touch-and-go helipad. Guest accommodations include a VIP stateroom on the main deck, along with four additional guest staterooms on the lower deck, allowing the yacht to host 12 guests. Crew accommodations are provided for 13.
Inside, an oval staircase connects all four decks, while the main-deck dining area opens directly onto the aft terrace through large sliding glass doors to create a seamless connection between indoor and outdoor living spaces. According to Heesen, the interior joinery and custom furnishings were produced in-house at the company’s luxury carpentry facility in Winterswijk, with finishes selected in collaboration with the owners.
Project Setteesettanta also introduces a first for the Dutch builder by placing the bridge on the fourth deck. That arrangement creates an observation deck above the owner’s accommodations while preserving the yacht’s low-profile appearance through a lightweight mast designed by Frank Laupman of Omega Architects and flush-mounted Starlink antennas. Aft, twin staircases wrap around a 13-foot infinity pool that leads down to the swim platform.
The yacht’s aluminum hull was tested at the Wolfson Unit in Southampton before construction. Powered by twin MTU 16V2000 M72 diesel engines producing 1,931 horsepower each, Project Setteesettanta has a reported top speed of 18 knots and a transatlantic cruising range of approximately 3,900 nautical miles at 12 knots. Quantum F45 electric-hydraulic stabilizers are fitted to improve comfort both underway and at anchor.
Project Setteesettanta will now undergo commissioning at the Heesen yard before heading to the North Sea for sea trials later this summer. Delivery to its owners is expected in December 2026.
