Heesen Yachts has completed the joining of the hull and superstructure for Project Grace, designated YN 21350. The yacht is the first unit in Heesen's new 50-meter Steel class. The operation, which lasted one week, began at the Talsma shipyard in Franeker, where the steel hull was fabricated. The hull was then transported by river and canal to Heesen's facility in Oss, where the main engines were installed prior to the joining procedure.

The yacht is equipped with two MAN engines, each rated at 882kW and compliant with IMO Tier III emissions standards. This is the first Heesen yacht to use this specific engine model.
Peter van der Zanden, Head of the Design & Development / Engineering Department, commented: "The new 50-metre Steel series gave us the opportunity to select the ideal engine for our brand-new platform. The MAN D2862LE438 was the clear choice, offering a power and efficiency profile that is perfectly calibrated for Project Grace's performance targets."

The exterior design is by British studio Harrison Eidsgaard. The design includes features such as low bulwarks and full-height windows. The studio is also collaborating with Heesen's engineering team on the layout to optimize guest and crew areas.

Ruud van der Stroom, Heesen CCO, commented: “Seeing the lines of this first 50-metre Steel yacht take shape is a powerful moment—it’s where the vision becomes a tangible reality. We are confident her iconic design will resonate strongly with a discerning owner.”

Project Grace is currently available for sale, with a scheduled delivery date in the first quarter of 2028.
