Heesen Yachts launches YN 20857

Heesen Yachts has launched a 57-metre full-custom, all-aluminium motor yacht of 920 GT at its shipyard in Oss, the Netherlands. Project Setteesettanta, YN 20857, was commissioned by owners who previously built a yacht with the shipyard.

The exterior is by Omega Architects, the interior by Cristiano Gatto Design. The yacht has a draft of 2.3 metres, four decks, a private owners' deck and an observation deck, accommodation for 12 guests in six staterooms and 13 crew. It is fitted with an electric/hydraulic hybrid power system and Quantum F45 stabilisers.

The owners have reserved the entire upper deck as their private area. The master stateroom lies forward, with 180-degree views and a private terrace of almost 200 square metres that also serves as a helipad. A VIP cabin sits forward on the main deck beside a gym, while four further staterooms, two twins and two doubles, are on the lower deck. An oval staircase runs through all four decks, and the main-deck dining area, towards the stern, opens onto the aft terrace through sliding doors.

YN 20857 is the first yacht in the Heesen fleet with her bridge on the fourth deck, a layout that gives owners an observation deck above the accommodation. A mast by Frank Laupman of Omega Architects and flat Starlink panels, used instead of traditional domes, keep the hull's profile slender. Aft, a double staircase runs around a four-metre infinity pool down to a swimming platform at the waterline.

The hull was tested at the Wolfson Unit in Southampton. The yacht is powered by two MTU 16V2000M72 engines of 1,440 kW each, for a top speed of 18 knots and a range of 3,900 nautical miles at 12 knots. The interior joinery, including marble selected by the owners in Verona, was built in-house at Heesen's Winterswijk facility.

"To see this project finally afloat is deeply moving," said Cristiano 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 journey."

"It is an honour to welcome these owners back to Heesen for a second yacht," said Jeroen van der Meer, CEO of Heesen. "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. YN 20857 asked a great deal of our engineers and craftspeople, almost all of it answered in-house, from the naval architecture through to the furniture built by our own carpentry shop in Winterswijk. I am proud of what the team has delivered for her owners."

Project Setteesettanta will remain in Oss for the commissioning of the systems before leaving for sea trials in the North Sea later this summer. Delivery is scheduled for the end of December 2026.
