The Tetrahedron Super Yacht is a very unique yacht, even in the concept yacht world. The company who designed the concept explains it best:
The design is instigated by the re-thinking of the form, superstructure and propulsion of the modern super-yacht into a radically simple enclosure and an elevated mode of travel above the water line. The superstructure form 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 known in ship and motor yacht construction through restrictions in ocean-going hull design.
The boat is only a concept but compared to some of the worlds most expensive yachts it may not be too over the top to exist in the near future. The details of the boat are where you start to realize it may only be a concept. Especially how it looks when it is under way. The yacht is technically a hydrofoil, and lifts above the surface when moving; It starts to look a bit more like a spaceship than a boat.
The strange design of actually being above the water is thought to actually have some benefits such as reducing drag from plowing through the water. The mechanisms for driving it are thought to be taken more from the aviation industry than the boating world.
There are no updates in recent years whether or not this concept will reach production but we may find out soon. It would certainly be difficult to fit in post ports and dockage around the world…
