Recreational water vehicle, the Seabreacher X from Innespace Productions, resembles a shark and can jump out of the water

Cue up the soundtrack to Jaws. Here comes Seabreacher X.

Want to perform exotic aquabatics in your next high-powered water toy? And do you want to do it in a watercraft that looks like a shark? Then the Seabreacher X is the advanced submersible (yes, submersible) vehicle for you. But you might want to get your order in quickly, because the company making them, Innespace Productions in northern California, plans on turning out just 10 of these made-to-order beauties, and it’s already building number five. (Innespace expects to have number 10 done by the middle of next year.)

More power
At the heart of the Seabreacher X is a 1,500-cc, three-cylinder, four-stroke Rotax engine capable of putting out 215 hp. A supercharged version pushes the output to 260 hp. The relatively quiet, low-emission engine relies on closed-loop water-based cooling and powers an axial-flow waterjet. The waterjet generates thrust, which funnels through a fully articulated vectoring nozzle, letting pilots steer the Seabreacher left or right, and up or down. For reverse, Innespace engineers added a drop-down reverse bucket that deflects thrust forward. The engine gives the Seabreacher X a top speed of 50 mph on the surface and 20 mph submerged.
Air for the engine comes in through a pair of snorkels, one built into the large dorsal fin, the other in the rear vertical fin.

The engine is reliable in salt and fresh water, and is relatively commonplace, according to Rob Innes, Innespace Productions founder. So local watercraft dealers should have replacement parts and be able to service it. The craft carries a 14-gallon fuel tank (regular or premium), which lets it cruise at 5 mph on the surface all day, says Innes. But run it hard, and you’ll be out of gas in 3 hr.
