When it comes to super yachts, oneupsmanship is the name of the game (note: what if you actually called your boat the Oneupsman Ship?!). That is, until the U-010 Undersea Yacht changed the vertical axis of the game. Now, it’s all about onedownsmanship.

Though still just in its conceptual phase, this  66.5m mega yacht is designed to travel both above water and below using diesel and electric power respectively. It’s also designed to traverse above and below the Great Blue in the utmost luxurious comfort. Including in its design are ports for a detachable mini-sub and two above-water personal watercrafts. Check out the pics below for more fantastic, wet luxury travel. Via Born Rich.
