What’s 16 feet long, can travel at 50mph on water and 25mph underwater, and despite its appearance isn’t actually a shark? You may well ask!Californian company Innerspace Productions, was started in 1997, by New Zealand boat builder Rob Innes and certified machinist Dan Piazza. After dallying with a Dolphin-inspired submersible, the pair took the project a stage further, to ultimately come up with the Seabreacher X.The Seabreacher X has a fully vectored thrust system that reproduces the tail action of real aquatic dwellers such as sharks and dolphins. However, few such creatures have a 260 horsepower, supercharged Rotax engine.The craft’s hand-laid compsite monocoque structure has a half-inch thick, impact resistant acrylic canopy. The cockpit and engine bay are rendered 100 per cent watertight by aircraft seals, that inflate to provide a positive pressure seal.Some other high tech features are incorporated into the two-seat vessel. A snorkel mounted video camera transmits live video to LCD screens for the pilot and passenger during dives. The craft also has GPS navigation, and on-board stereo with iPod docking.Although Innespace vessels start at about $65,000 USD, the limited edition X model costs a little over $85,000. The company plans to build just 10 of this particular model.So now you know what to buy that person who has everything. See www.seabreacher.com for more details.
