This new hydrosphere attaches to superyachts for epic underwater views – Robb Report

Sailors may soon have an exciting new way of seeing the world beneath the waves. Gresham Yacht Design has unveiled a remarkable new concept called “Hydrosphere” which will allow you to explore the ocean without ever leaving your ship.

The London outfit has yet to provide detailed information on the new contraption except for a stunning two-minute video on Vimeo. According to the accompanying blurb, the Hydrosphere immerses you in the surrounding ocean environment by pulling on the hull of the superyacht.

Much like a more sophisticated underwater version of Willy Wonka’s glass elevator, the ingenious structure deploys from the bottom of the ship in minutes. It can accommodate up to seven people, each of whom can soak up the seascape without ever getting their hair wet.

Essentially, the Hydrosphere will provide some of the views you might experience with a submersible. What sets it apart from a standard submarine, however, is ease and speed. You won’t have to spend time preparing a separate ship for launch, or organizing a dedicated captain and crew. You can simply walk down the stairs, take the “elevator” and enjoy unparalleled underwater views.


Special lighting illuminates both the interior space and the surrounding ocean.

Additionally, the Hydrosphere is equipped with special on-board lighting to illuminate the interior, as well as deep blue all-encompassing. This means it can be enjoyed whenever you want. In fact, the structure can even be deployed while the superyacht is sailing up to 2 knots. Conversely, when not in use, it retracts into the shell where it is protected by a durable external hatch.

Gresham has built a reputation for its innovative marine concepts. Earlier this year, the studio unveiled the 394-foot gigayacht Emir concept, which features an epic two-level ballroom at its center. And in 2020, Gresham’s 328-foot gigayacht Thor Explore made waves for a futuristic interior that looks straight out of a sci-fi movie.

This latest innovation may have a smaller footprint, but it’s easy to imagine the Hydrosphere becoming the newest water toy (on board) in the yachting world.
