Billed as aviation on the sea, the radical concept from a London-based architect flips traditional yacht design on its head with a complete rethink.

The futuristic vessel, called Tetrahedron Super Yacht, ‘levitates’ thanks to a vertical strut attached to a submerged torpedo-shaped hull, but it retains all of the luxuries one would expect on a multimillion-pound ship.

Designed by Jonathan Schwinge, renderings show spacious sun decks, an outdoor dining area, water toys and a set of retractable stairs into the sea.

Made from carbon fibre and duplex stainless steel, Tetrahedron Super Yacht can accommodate six passengers and four crew members in a 70.8-ft long pyramid that has four faces and six leading edges.

It has a ‘flying speed’ of 38 knots (43.7mph) above the water line and a take-off speed of 15 knots (17.2mph), with a range of 3,000 nautical miles.

Thanks to a unique design that controls roll forces, pitch and heave, the yacht would travel smoothly through rough water, said Schwinge.

At low speed the yacht sits gently on three underbelly hulls and at high speed the pyramid rises from the water as the hydrofoils rotate on the submerged HYSWAS (hydrofoil small waterplane area ship) hull.

This type of hull was previously developed by a number of companies, notably the Maritime Applied Physics Corporation in the US.

‘A three-based pyramid consisting of four faces and six leading edges provides fundamental stability and enclosure.’

He added: ‘Its form produces a pure, precise, logical and mathematical "roof” for which to connect to the hull assembly. 

Generally, simple forms are not known in ship and motor yacht construction through restrictions in ocean-going hull design.

‘Long distances are achievable with reduced out-of-water drag and stormy ocean conditions would incur virtually no slamming.’

Marcel Muller of INMAINCO Visionary Marine Management is the project manager and renderings were produced by EYELEVEL UK.
