At the 2026 Monaco Yacht Show, Royal Huisman presents a world premiere. The 85m / 280ft Royal Huisman Project 410, the world's largest sloop rigged sailing yacht.
The unveiling offers the clearest impression yet of this groundbreaking megayacht as she enters the final stage of completion at the shipyard in Vollenhove, The Netherlands. Her overall concept, exterior design and naval architecture are by Frers Design, with interiors by Wetzels Brown.
Project 410 has deliberately remained highly secretive since the shipyard team first announced its new commission, only limited information and selected glimpses of her design and construction have been shared. The most recent major update came with the spectacular turning of the super-sized aluminum hull in summer 2024.
Now, two years later, completion is drawing closer. In November, Project 410 will leave the newbuild facility in Vollenhove for transport to the shipyard's deepwater location near Amsterdam, where she will be launched, followed by stepping of her immense Rondal carbon mast and matching boom. The new visuals unveiled in Monaco provide the first opportunity to discover considerably more of her distinctive character.
A true sailor's yacht
She will become the world's largest sloop and rank among the ten largest sailing yachts in the world. Yet the brief has always gone beyond scale. The ambition is to create a true sailor's yacht. She will be elegant and comfortable, conceived to be ready to sail in a matter of minutes and to deliver rewarding performance even in lighter airs. Frers Design began with a hull form providing enough volume for two decks around a single mast and a proportionally small deckhouse.
Relatively high freeboards enhance privacy and protection, while the naval architecture combines low draft and high stability for reaching destinations at very low heel angles. Mani Frers of Frers Design: "Pure deck lines form a single arrow shape from bow to stern, incorporating the glass pilothouse, while the raked mast and uniquely engineered boom reinforce the yacht's dynamic profile."
The yacht's technical platform also incorporates solutions aligned with Royal Huisman's Tidal Shift sustainability program. Energy regeneration while sailing, a large-capacity battery storage system, quiet operation and the ability to operate in silent mode are among the technologies intended to reduce energy use while enhancing onboard comfort. The carbon mast, boom and integrated sailing system have been created by Rondal, Royal Huisman's sister company, bringing shipyard, engineering and specialist rig expertise together at an exceptional scale.
Designed from within
Unlike typical superyacht design, the story began from within. Wetzels Brown developed the interior experience as a foundation for the yacht's architecture and its relationship with the sea, before working with Frers Design on the naval architecture and exterior. The result is intended to combine the presence and performance of a powerful sailing yacht with the atmosphere of a private, relaxed retreat. Extra-large hull windows draw the horizon into the interior, while skylights and generous ceiling heights bring changing daylight, a strong sense of volume and spectacular view on the towering mast.
The principal living spaces, offering complete privacy, are arranged on one level within the hull beneath a refined deckhouse. A double-height main entrance leads toward the salon. Moving aft the veranda connects naturally with the beach club, creating a continuous sequence between interior, shade, sunlight and water. Forward, daylight guides the transition toward the private owner's suite. Gillian Brown of Wetzels Brown adds: "For us, the interior is about creating an environment where people can relax, feel close to the sea and create memories. The exterior, interior and experience of sailing have been developed as one continuous expression."
With the current project of the shipyard now approaching the water, this closely guarded project is entering a new phase. Peter Naeyé, CEO of Royal Huisman, adds: "Project 410 represents an extraordinary combination of vision, scale and innovation. The ambition was never simply to build the world's largest sloop, but to create a stunning sailing yacht that remains true to the pleasure and performance of sailing. Seeing her now approaching completion makes us immensely proud. She is an exceptional team achievement."
