Gresham Yacht Design is taking the party below the surface with the introduction of the Hydrosphere. The concept deploys a glass pod from the hull of a superyacht, where seven people can get a 360-degree underwater view. Onboard lighting will illuminate the surroundings for the lounge area, putting a spotlight on passing sea life and giving guests a full, submarine-like experience. Unlike a sub, it'll launch in a matter of minutes, even when the vessel is traveling at a maximum speed of up to two knots. When not in use, the Hydrosphere retracts back into the hull and is protected by an external hatch above the waterline.
