The most extreme superyacht concepts in the world

Extreme feature: a spider-like exterior design with four legs

Realised by Christian Leyk of coquine![design], Tobiko translates from Japanese as "flying fish roe". The 40-metre concept, with its imposing arachnid-like design, is a SWATH (small waterplane area twin hull) vessel that gives the illusion of flying low over the water. Although the yacht has parts that remain below the sea's surface, the living platform is "virtually unaffected by the waves", according to the designer. Most of the hull of this extreme superyacht concept does not exist, with just a shield against the waves and tender garage clipped to it. Instead, the studio strengthened the backbone of its inter-deck space and put all the yacht's systems inside. There’s one lounge, two guest suites, a semi-open galley area and a small crew space, while the upper deck has a bridge and sundeck space.

Extreme feature: able to "fly" at exhilarating speeds

Plectrum is a 'flying' yacht concept that takes inspiration from the more contemporary America’s Cup sailboats - specifically the Luna Rossa design - and would be the largest example of foiling technology installed on a yacht. Designed by Lazzarini Design Studio, the yacht would have an eye-watering top speed of 75 knots thanks to three hydrogen-powered motors, capable of 5,000hp each. Plectrum is also envisioned with an adjustable beam of up to 20 metres that can be reduced to 15 metres when the yacht is berthed or at anchor.

Extreme feature: its futuristic hull shape

This 80-metre catamaran concept was designed by Andy Waugh Yacht Design, who took his inspiration from the automotive and aeronautical advances seen in the 1920s. The futuristic SWATH hull would allow for several technical developments, such as an estimated 70 percent reduction in pitch and roll movements compared to a conventional monohull superyacht, for greater comfort and safety while on board. Renderings also show retractable inflatable sails, suggesting that the yacht will benefit from added wind power.

Extreme feature: a huge indoor garden

This entirely carbon-neutral, 110-metre superyacht was revealed by German studio 3deluxe and comes complete with a "garden-like" interior. VY-01 will be powered by fuel cells driven by hydrogen and recharged by bio-methanol alongside silent electric engines, for a range of 3,240 nautical miles. Described by the studio as "a floating garden of Eden", the interiors benefit from sensor-controlled louvers that wrap around the superstructure.
