Royal Huisman is taking sloops to new heights, literally.

The Dutch yard is building a 264-foot sailing yacht with what it says is the world’s tallest mast. The aptly named Sky, previously known as Project 411, will be fitted with a record-setting Rondal rig that will tower 305 feet. That makes the yacht roughly the same height as the Statue of Liberty from ground to torch. After launch, Sky will become the tallest sailing yacht on the seas. (That title currently belongs to the 417-foot Koru, reportedly owned by Jeff Bezos, which has three masts that span between 213 and 280 feet.)

In addition to that very tall and powerful carbon rig, Sky showcases a sleek aluminium body with optimised weight distribution that will make her quicker than the wind and faster than a motor yacht of a similar length, according to Royal Huisman. A lift keel and twin composite rudders also give her the manoeuvrability of a smaller sailer measuring under 164 feet, while an integrated sailing system makes her easy to handle.

Sky will be a head-turner, too. Malcolm McKeon Yacht Design penned a stylish contemporary exterior, while Winch Design created an elegant and inspiring interior. Inspired by nature, the living quarters showcase clean, sculptural lines, natural textures, and neutral palettes. The indoor-outdoor layout includes six spacious cabins, with the full-beam owner’s suite offering direct access to a large aft beach deck with an extendable swim platform and fold-out terraces. Expansive full-height windows and a raised bed in the suite also provide the owner with sweeping panoramic views of the ocean.

There are, of course, many spaces to relax and unwind, including a spa amidship with a sauna, a steam room, and a folding platform that opens to the water. There’s also a watersports centre for any budding explorers. In addition, Sky can carry a 39-foot tender, another crew/rescue tender, two water scooters, and additional water toys. 

“Every detail is designed to enhance life onboard—from wellness zones and water sports areas to entertainment spaces filled with natural light,” designer Andrew Winch said in a statement. “Sky is the next generation of sailing yachts with a unique signature in design for a true sailor and innovator.”

Royal Huisman first presented Project 411, originally nicknamed Noir, in April 2024. It was being built for an experienced yachtsman, but now appears to be seeking a new owner. The yard says the design and the majority of the engineering is already complete, with Sky expected to hit the seas in the spring of 2030. 

“Ready for an owner who wants to sail the world, Sky is set for delivery in spring 2030: a super-sized sailing yacht developed to explore the far corners of the globe in the most eco-friendly way compared to XXL motoryachts,” adds Royal Huisman CEO  Peter Naeyé.
