Jet-propelled surf board
The inventors of a jet-propelled surfboard so they are struggling to keep up with demand.
The Jetsurf is a cross between a surf board and a jet-ski and can reach speeds of 40mph.
The flat carbon fibre board has a 100cc engine attached to the back and features a 2.5 litre fuel tank.
Users stand upright on the board and use their body weight to steer it from side to side like a surfer would.
The craft sucks in water from the front and shoots it out behind, helping it to build up speed very quickly.
Meanwhile, an electronic leash which is attached to the surfer's wrist acts as both a throttle and an emergency kill-cord.
It was developed by jet-surf.com and the company says it is struggling to keep up with demand for the £7,000 product.
Technician Ben Gibson said: "It handles like a surf board and the weight of it isn't much more than a kite board or a surf board.
"Out of all the sports out there it is actually closest to snowboarding, as you are not getting pulled around or waiting for waves like on a surf board.
"We make 20 boards a month, all handmade, and constantly have a waiting list for them."
