Innespace Seabreacher (or Sea Breacher) is a two-seat semi-submersible personal watercraft "submarine", with a shape based on that of a dolphin, and the ability to imitate a dolphin's movement. History The watercraft was designed and developed by two engineers—New Zealander Rob Innes and his partner American Dan Piazza—who are also the founders of the American company Innespace Inc., which markets, builds and sells the semisub watercraft to customers. 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 and Dennis "Dusty" Kaiser in 1987 with his boat, Noland Won. Specifications The two seat vessel is powered by an Atkins Rotary Marine engine coupled to a Hurth V-drive transmission. Seabreachers are available in a wide array of colour specifications and insignias. References External links See also DeepFlight Merlin Personal water craft brands Personal submarines
