Would you dare to ride this shark? Read more inside and decide.
This seabreacher looks like a great white shark, complete with dorsal fin, gaping jaws and rows of dagger-sharp teeth. At 16.5ft in length, it is even the same size as one.
Unlike the real thing, it also has a 260hp engine, which powers it to 50mph above water, and 20mph below it.
"The seabreacher is really for people with a large disposable income who want to have fun,' explains Rob, the co-creator. "It's pretty popular in the Middle East, but we've also sold them to clients in Korea and the Caribbean."
Rob, 37, is a watersports fanatic. And along with friend Dan Piazza, 52, he has turned his hobby into a thriving business.
The pair built their first submersible 12 years ago and today their company, Innespace, has a year-long waiting list of rich adrenaline-junkies eager to buy one of their custom-built playthings.
Toys they may be, but each one costs about £60,000.
It can jump 12ft from the surface.
So how long does it take to master the controls of an artificial shark? While it is more difficult to drive than a conventional pleasure cruiser, Rob insists he can teach someone the basics in just three to four hours.
