Yes alien spaceships are coming to an ocean near you. With the design of the Tetrahedron Super Yacht, inspired by re-thinking the form, superstructure and propulsion of the modern superyacht into a radically simple enclosure and an elevated mode of travel above the water line. Conceived by London based architect Jonathan Schwinge, this futuristic concept could very soon become a reality.
The form of the yacht is reduced to the absolute geometry of a Tetrahedron. A three-based pyramid consisting of 4 faces and 6 leading edges provides fundamental stability and enclosure. Its form produces a pure, precise, logical and mathematical ‘roof’ from which to connect to the hull assembly. Generally, simple forms are not used in ship and motor yacht construction due to restrictions in ocean-going hull design.
The Tetrahedron will have the appearance at high-speed of levitating over the water: a boat that can fly. This is produced by a HYSWAS (Hydrofoil Small Waterplane Area Ship) hull, that is comprised of a single vertical strut onto a single submerged torpedo hull. The vessel will lift out of the water at speed on side-mounted adjustable hydrofoils. Long distance, smooth travel through rough water at high speeds will eliminate heeling and slamming in rough waters and would banish seasickness forever.
The hull has two working waterlines for its operation. At low speed the Tetrahedron sits gently onto three underbelly hulls. At high-speed the hydrofoils rotate on the lower submerged hull, causing the effect of mysteriously raising the triangle out of the water.
The concept design of this HYSWAS craft is based upon an existing hull design which was developed by several companies, notably the Maritime Applied Physics Corporation in America, and was proven by their technology demonstrator ‘The Quest’ in 1995.
An auto-pilot ‘fly-by-light’ system taken from the aviation industry would control difficult roll forces and maintain foil born speed. This would also control pitch and heave.
Long distances are achievable with reduced out-of-water drag and stormy ocean conditions would incur virtually no slamming. Improved efficiency is driven by elevated hydrofoil propulsion and would be an inherent performance benefit of this type of design.
The future of a superyacht such as this could come faster than you think. Jonathan Schwinge updated me this week on the project, “We are currently working with a large superyacht yard and the design has been developing forward. Much of the development has a new feel – the ‘Trimaran’ 3 hull has now been replaced by a black coated ‘bat-form hull’ with special retractable ocean landing systems.” The Tetra Project is being managed by Marcel Müller at INMAINCO Visionary Marine Management.
