Dutch shipyard Royal Huisman has successfully turned the hull of Project 410, also known as the “85m New World Sloop,” which will become the world’s largest yacht with a single mast.

Project 410 is a collaboration between the owner, Frers Design—responsible for the overall concept, exterior design, and naval architecture—and Wetzels Brown, which is handling the interior design. The project is being engineered by Royal Huisman’s in-house team, with the support of specialised co-makers.

Initially revealed at the St. Barths Bucket Regatta 2022, the project has remained largely undisclosed to date.

The aluminium hull, constructed at Royal Huisman’s Vollenhove shipyard in the Netherlands, required an extension of Hall 2 to accommodate the vessel’s size.
