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: revolutionary self-heating masts

Steve Kozloff lifted the lid on an 170-metre superyacht concept that comes complete with foldable masts and its own dedicated aircraft hangar. The masts represent a groundbreaking feat of engineering that would be able to rotate, tilt, heat up to avoid icing and set their own sails. The yacht is a luxury vessel first and foremost, but it has also been designed with scientific research in mind and will boast an ice-classed hull.

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.

Extreme feature: its delicate folded superstructure

ilGatto's origami-esque lines are courtesy of Turkish designer Aras Kazar, who was inspired by "the regal spirit of the Leo zodiac". Built in aluminium and tempered, lightweight glass, the design sees all glazing able to be fully opened – heightening guests' connectivity with nature and allowing ocean air to circulate throughout the vessel. It also encourages outdoor play with an expansive floating dock and tender garage, able to store limousine tenders and a variety of water toys. Leisure features abound on this 140-metre model, including a helipad, swimming pool, cinema room and fully-equipped gym.
