Royal Huisman presented SKY, an 81-metre ready-to-build sloop concept with a 93-metre mast and design input from Malcolm McKeon Yacht Design and Winch Design.

Royal Huisman presents SKY, a rare opportunity for a visionary owner: a pedigree 81 meter / 264 feet sloop crowned by the world’s tallest mast. Malcolm McKeon Yacht Design (MMYD) developed the ambitious naval architecture and the contemporary, head-turning exterior styling. Winch Design created the elegant and inspiring interior of this super-sized sailing yacht. The carbon rig by Rondal will have an air draft of 93 meters / 305 feet, which equals the towering height of the Statue of Liberty from ground to torch.

With the design and the majority of engineering already completed, SKY is ready to build: the realization of the Ultimate Expression of Personal Freedom. A Spring 2030 delivery — rather than the customary six or more years for the full process from architect briefings, multiple design meetings until delivery — means SKY turns ambition into ownership easier and sooner.

The world’s tallest sloop SKY is created for world cruising with strong sailing performance. Her long waterline, lift keel, full aluminum construction with optimized weight distribution, combined with a powerful Rondal rig, will make SKY a true XXL superyacht. She sails faster than the wind and faster than a similar length motoryacht. At the helm, the controls, integrated sailing system and twin carbon composite rudders will provide the maneuverability and simplicity of a performance sailing yacht under 50m / 164ft. The flybridge and various seating areas enable the versatility of both open air living, superb visibility and protection from the sun. Owner and guests will experience a close connection to the water due to the aft beach deck with extendible swim platform, full-beam mid lazarette with folding platforms either side and cockpit with folding bulwarks.

SKY will build on the successful collaboration with Royal Huisman and MMYD, who created Sarissa, the 60m / 197ft high performance sloop and winner of 10 prestigious awards in 2024
