Dutch yard Royal Huisman has marked a major construction milestone on its 81-metre sailing yacht known as Project 412, with the hull successfully turned at the yard’s facility in Vollenhove.
With the hull turning now complete, the team will proceed with the next stages of construction, focusing on onboard systems development and outfitting. The bow section, currently nearing completion in hall three, will be joined to the main hull within the coming days.
The project was first announced in May 2025 as an 80-metre-plus “super-sized” aluminium sailing yacht commissioned by a returning owner. Now confirmed to measure 81 metres, the build is progressing as part of the yard’s Trident 810 series, with the hull turning signalling the transition from primary structure to outfitting and systems integration.
A hallmark moment in any superyacht build, the turning of the aluminium hull offers the first clear view of the yacht’s scale. The construction features a distinctive chine running from bow to stern, while the vessel is being developed as a contemporary flybridge schooner designed for world cruising.
As previously reported, Project 412 will be equipped with a state-of-the-art carbon rig supplied by Rondal, combining performance with sail-handling comfort and innovation.
Royal Huisman’s new CEO, Peter Naeyé, commented on the latest milestone. He said: “The hull turning is always a proud moment because you see the result of thousands of hours of craftsmanship in its full presence.
With Project 412, we are again pushing the boundaries of true sailing at superyacht scale, and we are excited to see this fine second edition of the Trident series progress to the integration and finishing phases that define the Royal Huisman experience.”
Project 412 is the second hull in the Trident 810 series, building on a proven platform first delivered in 2020. According to the yard, the series allows owners to benefit from a shorter construction timeline while still achieving a fully bespoke result.
According to BOATPro, the mammoth build will be joining two other projects at the yard’s facilities in Vollenhove: the 85-metre Project 410, also known as the world’s largest single-masted sailing yacht, and the 81-metre Project 411.
