American studio Gary Grant Design has unveiled a new 153-metre hybrid superyacht concept, which, if built, would be the largest hybrid superyacht in the world.
Intending to redefine design, speed and sustainability at a "giga-yacht scale", the mammoth yacht concept is centred on an advanced hybrid propulsion system, offering zero-emission capabilities alongside speeds of up to 50 knots.
Studio founder, Gary Grant, explained: "This design has been in the works for 12 months and has been developed around the propulsion system as well as numerous mathematical performance models."
Power is from Wärtsilä 31 engines, a hybrid electric system including a large energy storage system, as well as electric drives powering two waterjets. Additional twin Rolls-Royce MT30 engines also power two further Wärtsilä waterjets for maximum performance.
Alongside quick top speeds, the yacht's hybrid propulsion allows for silent, battery-electric cruising in both sensitive marine reserves and eco-regulated ports. A smart energy management system also distributes power flows to ensure a minimal ecological footprint.
With a portfolio of unusual, eye-catching designs, including Crazy Me, Adler II and Margaux, the studio has once again brought its trademark sculptural aesthetic to the 153-metre.
A signature use of formed and sculpted glass characterises the yacht's profile, while floor-to-ceiling glass walls and ceiling heights exceeding 5.2 metres in the main saloon define the interior. An open-plan layout is championed on board, alongside a "convertible" beach club for immersive indoor-outdoor living.
