Heesen Marks Major Milestone as Project Grace Hull and Superstructure are Joined

September 16 2025

Heesen Yachts announces a key milestone in the construction of YN 21350, Project Grace, with the joining of her hull and superstructure. Project Grace is the inaugural yacht in Heesen’s new 50-metre Steel class.

The joining of the hull and superstructure marks the culmination of a week-long operation that began in Franeker, in the North of the country, at Talsma, Heesen's partner for steel hull fabrication. The hull was then transported via the country’s rivers and canals to Heesen’s shipyard in Oss. Upon arrival, Heesen’s engineering teams installed the main engines before completing the joining procedure.  

For the first time, Heesen has equipped a yacht with two MAN (IMO Tier III) engines, each delivering a maximum power of 882kW.

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."
