Italian studio Cristiano Gatto Design has unveiled the first interior renderings of Heesen's full-custom superyacht Project Setteesettanta, ahead of her anticipated delivery at the end of December. The 57-metre motor yacht is currently under construction at the Dutch yard's facilities in Oss and was last sighted on sea trials in August, a month after her launch.
The 920GT all-aluminium project (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.
She 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, generous exterior decks and extensive onboard comfort.
Longstanding Heesen collaborator Frank Laupman, founder of Omega Architects, led the project's exterior design, while her interiors were born from the boards of Cristiano Gatto, founder of Cristiano Gatto Design. Project Setteesettanta stands as the 12th collaboration between Gatto and the Dutch shipyard, with the designer also entrusted as the owners' representative throughout the yacht's construction.
"Setteesettanta is the result of an exceptional relationship with owners who know exactly what they want from their yacht," said Gatto. "Their extensive experience of life at sea has been fundamental in shaping the project. Our objective was to translate that experience into spaces that feel entirely natural to them, with the right balance of privacy, comfort and functionality."
He continued: "Every decision, from the overall layout to the smallest detail, has been driven by the way they intend to use the yacht. That, to me, is the true meaning of full-custom design."
According to the studio, the design philosophy on board stems from the concept of "artistic craftsmanship", where each element is not merely functional or decorative but "an individual artistic expression". The interiors have been designed to explore the relationship between material, light and form, with aesthetic details such as 20 different door designs (each incorporating references to artists or artistic movements) and sculptural surfaces where light appears to emerge from within.
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, in addition to quarters for up to 13 crew.
Her 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.
A key feature on board Project Setteesettanta (which translates to "seven and 70" in Italian) is its four-metre infinity pool on the main deck aft. A set of steps on either side of the pool leads 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 is also 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 previously noted that this doesn't affect her silhouette, however, which features a "light [and] unobtrusive" mast by Laupman and flat Starlink panels in place of traditional domes.
The yacht features Van Oossanen Naval Architects' Fast Displacement Hull Form, which is expected to offer a top speed of 18 knots and a transatlantic range of 3,900 nautical miles at 12 knots. Her interior joinery, which has been carefully matched with the marble hand-selected by the owners in Verona, has been crafted in-house at the Heesen interior facility in Winterswijk.
Exclusive BOATPro data reveals that Heesen has eight yachts currently under construction ranging from 49 to 72 metres in length, including its largest Steel superyacht to date.
