The two New Zealanders Rob Innes and Dan Piazza started out 25 years ago as Innespace, later Innespace Productions in Northern California, with small, fast and also limited submersible watercraft of various propulsion types. For almost 15 years, they have been building fish-shaped high-performance fun boats by hand - expensive, but unique and spectacular. Their latest coup is the "Jet Shark", a further development of the "Seabreacher", which is delivered to solvent customers in exclusive small series as a 5 metre long shark, dolphin or orca, individually airspray-painted with a 1.5 litre supercharged four-stroke engine (230 hp) and water jet propulsion.

"Jet Shark" is larger, has a navalised 500 hp V8 Corvette engine in its belly and can accommodate four people in the air-conditioned gullwing cabin. It can glide on the water at up to 50 knots, but can also perform all kinds of tricks in and above the water - almost like a real dolphin. Even with this propulsion system, it can travel submerged under water at 20 knots for up to half a minute - not deep, but just enough so that the periscope camera in the dorsal fin can be used to observe what is happening above water. Although the "Jet Shark" is still a prototype, the demand for the racy predecessor model suggests that there will also be considerable demand for the more spacious fun vehicle.

With this propulsion system, it is not yet the diving-swimming-flying wool-milk sow at sea, but equipped with an electric drive and equipped for operational applications, such platforms would certainly also have a future in military areas. At least the combat swimmers would have fun with it!
