SKY — THE WORLD’S TALLEST SLOOP IS READY TO BUILD – An 81-metre vision of power, poetry, and engineering excellence!
Winch Design unveils Project Sky, an extraordinary 81-metre sloop set to become the tallest sailing yacht mast ever built. Conceived through an exceptional collaboration between Winch Design (interior), Malcolm McKeon Yacht Design (naval architecture and exterior), and the world-renowned Royal Huisman shipyard, Sky represents a groundbreaking chapter in next-generation sailing superyachts.
A sailing giant with unmatched performance
Designed for effortless world cruising, Sky combines elegance, power, and state-of-the-art engineering.
Her long waterline, lifting keel, full aluminium construction with perfectly optimised weight distribution, and a powerful Rondal rig place her firmly in “XXL superyacht” territory.
Featuring the tallest sloop rig ever created — exceeding today’s world record by four metres — Sky is engineered to sail faster than the wind and outperform motor yachts of similar length.
Twin carbon-composite rudders, an integrated sailing system, and intuitive controls bring the handling characteristics of a sub-50m performance yacht to an 81-metre vessel. Precision, ease, and exhilaration blend seamlessly at the helm.
A sanctuary of light, nature and refined serenity
Winch Design’s interior for Sky draws inspiration from the harmony of natural landscapes. Sculptural lines, organic textures, and a soft, calming palette create a serene retreat for up to 12 guests. Every detail is crafted to blur boundaries between inside and out, offering an elevated architectural interpretation of coastal beauty.
At the heart of the yacht, the full-beam owner’s suite opens directly onto the expansive aft beach deck. Bathed in natural light from floor-to-ceiling windows, the stateroom features a raised bed positioned for uninterrupted ocean views. By day, it is airy and radiant; by night, it transforms into a cocooning sanctuary — a sensation akin to sleeping beneath the stars.
The suite includes his-and-hers dressing rooms and bathrooms, each featuring striking cylindrical showers.
Across all guest accommodations, contrasting timbers, ambient lighting, and refined materials create a cohesive aesthetic. Spacious layouts and subtle textures ensure an atmosphere of quiet luxury and connection to the sea.
Wellness, tranquility and the spirit of exploration
Midship, a dedicated spa sanctuary invites total relaxation, complete with sauna, steam room, and a fold-out platform opening directly to the ocean — a dreamlike spot for cooling off after a long day under sail.
This area connects effortlessly to the watersports embarkation lounge, featuring a self-service bar nook and direct access to the sea. Whether for adventure or reflection, this zone forms a harmonious balance between energy and serenity.
Ascending the sculptural staircase to the main deck, guests are welcomed into an open-plan lounge and dining area finished with flamed dark timbers, polished metals, bold stone, and soft textures. Full-height sliding doors dissolve the boundaries between interior and aft deck, extending the living space into the open air.
Outside, the cockpit offers elegant alfresco dining, sculpted seating, and fold-out balconies on both port and starboard, enhancing proximity to the water. Low-level lighting enriches the evening ambiance, while panoramic views remain uninterrupted from bow to stern.
A unique opportunity — Sky is ready to build
With design, naval architecture, and most engineering already completed, Sky is fully ready to enter construction. Scheduled for delivery in Spring 2030, she offers a vastly accelerated build timeline compared to the traditional six-year creation process.
This presents a rare opportunity for a visionary new owner to personalise the layout and interior style, bypass years of development, and bring to life a truly one-of-a-kind supersized sailing yacht.
Project Sky is more than a yacht — it is a bold new benchmark in the world of large performance sailing vessels.
