Aqua is fueled by liquified hydrogen, stored at extremely low temperatures, in two 28-ton, vacuum-isolated tanks. A spiral staircase in the center of the boat leads to the bottom deck where these monoliths sit behind strengthened glass, designed to keep the liquid hydrogen stable at -253°C (-423°F)Amongst many other features, this superyacht would have an expansive indoor health and wellness center featuring a gym, a hydro-massage room, and a yoga studio. There are also indoor-outdoor entertaining spaces with a formal dining area that seats 14. The five-deck yacht would accommodate 14 guests and 31 crew members
