Royal Huisman has completed another major step in the build of Project 406 – a magnificent 171ft/ 52m six-deck, true sportfish superyacht, set to become the world’s largest – as the main superstructure was skillfully lowered onto the hull by overhead cranes.


The carefully planned installation of the decks took place inside Hall 2 at the shipyard’s headquarters in Vollenhove and was attended by the owner’s team, naval architects, designers and specialist consultants alongside the team from Royal Huisman.

Preparation and fit-out of the remaining four decks of this vessel is now underway. In parallel, the shipyard continues working on the board systems and other technical installations. The work includes innovative features and components, such as laser-powered exterior lighting. Everything will be brought together to complete the perfect fit in the period leading up to her launch in 2023.


Even in the exceptional world of superyachts, Project 406 stands out as a unique vessel. Not only will she be largest sportfish yacht anywhere in the world but, she is meticulously engineered and has all the amenities expected of a superyacht. Her design is extremely distinctive, with a long bow and high bulwarks sweeping through a clear sheer to a low and uncluttered cockpit aft. The high tower offers outstanding views with a downward angle on the water for specialized fishing.

Apart from its practical function, the tower also offers a superb viewing platform for guests, who can follow all the action below. And a further element of surprise: a skylounge that offers an impressive view at the daytime theatre of sportfishing. By night, the skylounge provides the relaxed ambience and stunning outlook of the skies.



Vripack Yacht Design Studio is responsible for the project’s naval architecture, as well as the dramatic exterior and yet-to-be-revealed interior design. Royal Huisman is the builder with a very capable and innovative engineering and production team well suited to delivering such an unique project. The shipyard team has worked together with the owner’s representative and his other team members which includes: Bush & Noble for expertise on sportfishing and classic yacht forms; Hampshire Marine for the day-to-day technical aspects at the shipyard.


Royal Huisman has built its reputation by fulfilling the most ambitious and challenging dreams of its clients,” commented Royal Huisman CEO Jan Timmerman. “… It is a privilege to be selected by the owner’s team to realize this unique sportfish superyacht... Project 406 will be another masterpiece of creativity, innovation and expertise. And always, uniquely, an individual Royal Huisman motoryacht.”
