One Mast. 280 Feet. Royal Huisman's Record-Breaking Sloop.

There's nothing particularly unusual about an 85-meter superyacht anymore. Until someone decides to put a single mast on it. Royal Huisman's Project 410 stretches 280 feet from bow to stern, making it the world's largest sloop-rigged sailing yacht upon completion. Recently unveiled at the Monaco Yacht Show, the Dutch-built giant is approaching completion at the shipyard's facility in Vollenhove, Netherlands.

Frers Design handled the naval architecture and exterior, developing a long, arrow-shaped hull with a relatively small glass deckhouse and an enormous carbon-fiber rig engineered by Rondal. Despite its size, Project 410 is intended to sail efficiently in lighter winds, with a low-draft, high-stability hull designed to minimize heel. The engineering is ambitious, but the objective is surprisingly simple: build a yacht this large that still feels like a proper sailboat.

Inside, Wetzels Brown took an unconventional approach, developing the living spaces before the exterior architecture was finalized. Oversized hull windows, skylights and a double-height entrance bring natural light below deck, while the main salon connects aft to a veranda and beach club. Underneath it all, a regenerative energy system captures power while sailing, feeding large battery banks that support quieter operation and a silent mode.

Project 410 will rank among the ten largest sailing yachts ever built, but its most interesting feature isn't its length. It's the commitment to doing something increasingly rare at this scale: letting the wind do the work.
