British studio Gresham Yacht Design has recently introduced the next best thing in yacht design with their Hydrosphere, an underwater viewing platform that fits up to seven people and lowers from underneath the bottom of the vessel in minutes in order to observe passing sea life.
The Hydrosphere can be deployed while the yacht is in motion (in speeds up to two knots), and exterior lighting illuminates the surrounding water, which allows for both day and night use. Also, unlike personal submarines or other submersibles that require a specialist or pilots to drive and deploy, the Hydrosphere operates simply and quickly at the push of a button.
