57m full-custom Heesen superyacht Project Setteesettanta launched

22 July 2026 • Written by Gemma Harris and Emily Dawkins

Dutch yard Heesen has announced the launch of its 57-metre full-custom superyacht known as Project Setteesettanta from its facilities in Oss, the Netherlands.

The 920GT all-aluminium yacht (also known as YN 20857) was commissioned by "experienced yacht connoisseurs" and returning Heesen clients who sought a yacht for spending time at sea with family and friends.

Project Setteesettanta marks the second Heesen yacht commissioned by her owners, who returned with a clear brief for their next build. As such, the 57-metre features a shallow draught of 2.3 metres for easy access to shallow anchorages, paired with generous exterior decks and extensive onboard comfort.

Sea trials will commence in the North Sea later this summer, with delivery scheduled for the end of December 2026

The yacht's exterior is owed to Frank Laupman and the team at Omega Architects, while Cristiano Gatto Design is responsible for the interiors. Project Setteesettanta marks the 12th collaboration between Cristiano Gatto and the Dutch shipyard, with the designer additionally entrusted as the owners' representative throughout construction.

"To see this project finally afloat is deeply moving," said Gatto. "Every element of her interior was conceived from scratch and refined down to the finest detail, with nothing left to chance. She has truly been a labour of love. Drawings and renderings can guide the design process, but nothing compares to the moment when a project becomes reality. Seeing the spaces come to life exactly as envisioned is immensely rewarding, and I am deeply grateful to the owners for the trust they placed in us throughout this remarkable journey."

The yacht is expected to have a top speed of 18 knots and a transatlantic range of 3,900 nautical miles at 12 knots

A key feature on board Project Setteesettanta (which translates to "seven and 70" in Italian) is its four-metre infinity pool found on the main deck aft. A set of steps on either side of the pool lead guests down to the swimming platform, which features a hydraulic transformer platform for easy access to the water. Tenders and toys are stowed in the forward garage behind gull-wing doors, with additional storage for toys tucked behind the lazarette.

Project Setteesettanta marks the first yacht in the Heesen fleet to have the bridge on the fourth deck, granting the owners an observation deck above the accommodation. The yard notes that this doesn't affect her silhouette, however, which features a "light [and] unobtrusive" mast by Frank Laupman and flat Starlink panels in place of traditional domes.

The custom yacht features a six-cabin layout, including a generous upper deck owner’s apartment complete with 180-degree views and private access to the nearly 200-square-metre foredeck, which can also function as a touch-and-go helipad. A VIP cabin is found on the main deck, alongside a fully equipped gym. There are a further four guest cabins – two twin and two double configurations – on the lower deck. There is further accommodation for up to 13 crew members. 

The four decks are connected by an elegant oval staircase that runs back-to-back with the crew staircase for improved space optimisation. On the main deck, the dining area, which is located near the stern, blends with the aft terrace via wide sliding doors. The yacht's interior joinery, which has been carefully matched with the marble hand-selected by the owners in Verona, was crafted in-house at the Heesen interior facility in Winterswijk.

The project was last sighted as a bare structure, en route to outfitting in 2024, a year after construction began in 2023

Jeroen van der Meer, CEO of Heesen, added: “It is an honour to welcome these owners back to Heesen for a second yacht. A returning client is the highest compliment a shipyard can receive. Experienced yacht owners arrive with real ambition and set genuine challenges for the yard and its people, and we welcome that, because it is exactly what moves us forward and sharpens our craft."

He continued: "YN 20857 asked a great deal of our engineers and our craftspeople, almost all of it answered in-house, from the naval architecture through to the furniture built by our own luxury carpentry shop in Winterswijk. I am proud of what the team has delivered for her owners.”

There are nine yachts currently under construction at Heesen ranging from 49 to 72 metres in length. In recent news, the Dutch yard delivered its 55-metre Steel superyacht Pa’lante.
