"A new special superyacht feature that allows guests to descend through the water to enjoy a submerged viewing experience from their superyacht has been unveiled by Gresham Yacht Design.
Known as the “Hydrosphere”, the concept immerses guests in the surrounding ocean environment through the hull of the vessel. It replicates the experience of diving in a submersible without ever leaving the yacht.
Offering 360-panoramic views of the underwater world, the Hydrosphere can seat seven guests and takes just “minutes” to deploy from the bottom of the boat. It’s this that sets the Hydrosphere apart from a submersible, according to designer and studio founder Steve Gresham."
