Innespace Seabreacher (or Sea Breacher) is a two-seat submersible personal watercraft, with a shape based on that of dolphin, and the ability to imitate a dolphin's movement.
Designed by Rob Innes and Dan Piazza of the American company Innespace it is the production model of the single-seat Innespace Dolphin. The concept came from VASH (variable attitude submersible hydrofoil), which was invented by Thomas "Doc" Rowe[1] and Dennis "Dusty" Kaiser in 1987 with his boat, Noland Won.[2][3]
The two seat vessel is powered by an Atkins Rotary Marine engine coupled to a Hurth V-drive transmission.
