Inside 112m Hydrogen-Electric Superyacht Concept Aqua

10 February 2020 • Written by Miranda Blazeby

Sinot Yacht Architecture and Design's 112 metre hydrogen-electric yacht concept Aqua was designed for "a discerning, forward-looking owner".

Extensively developed over a period of five months, Aqua was created in collaboration with Lateral Naval Architects, which developed the yacht’s hydrogen technology and naval architecture.

Fusing ground breaking technology with cutting edge design, Aqua features a hydrogen-electric system. The hydrogen propulsion package is based on the use of liquified hydrogen, which is stored at -253C degrees in two 28 ton vacuum isolated tanks.

The hydrogen is converted into electrical energy by proton exchange membrane fuel cells, with the generated energy powering the propulsion, auxiliary systems and hotel services. Water is the only by product of the system, which also sees large batteries buffer the generated electricity. The result is a top speed of 17 knots, cruising speed of 10-12 knots and range of 3750 nautical miles.

Speaking about the concept, designer Sander Sinot said: “For development of Aqua we took inspiration from the lifestyle of a discerning, forward-looking owner, the fluid versatility of water and cutting-edge technology to combine this in a 112 metre superyacht with truly innovative features."

"Our challenge was to implement fully operational liquid hydrogen and fuel cells in a true superyacht that is not only groundbreaking in technology, but also in design and aesthetics."

The interior meanwhile has been designed around providing as much privacy and space as possible. Accommodation is for a total of 14 people and 31 crew. The full 15.4 metre beam owner’s “pavilion” occupies the front half of the upper deck.

Key features of the owner's pavilion include an open plan layout divided by wooden screens, floor to ceiling windows on the port and starboard sides, a large central skylight and crafted wooden structure. The apartment also include a large bathroom, dressing room and spa.

Other interior features include the Aqua room, which is located at the bow at the far end of the owner’s pavilion for far reaching ocean views and a “top-of-the-world” feeling.

Aqua also features an indoor health and wellness centre with a hydro massage room, yoga space and workout floor.

A circular staircase sits at the core of the yacht, linking all five decks. Described as “a true spectacle”, the staircase bypasses the two hexagonal liquified hydrogen tanks, which sit behind a screen of strengthened glass.

The exterior meanwhile has been inspired by “ocean swells”, and features a curved top deck, integrated bow observatory, glass band windows and a raised front profile.
