A JetLev jetpack in use. The JetLev is a water-propelled jet pack powered through a floater derived from jetski technology attached through an umbilical to the backpack which contains two nozzles and two control arms, in a configuration like traditional rocket belts and gas turbine jet belts. The JetLev also functions underwater, allowing users ...
Jetlev water powered jet pack A Flyboard with its distinctive configuration of having the nozzles located below the pilot's feet. The 21st century has seen a new approach to jet packs where water is used as a high-density propulsion fluid. This requires a very large mass of fluid that makes a self-contained jet pack infeasible.
A Flyboard rider stands on a board connected by a long hose to a watercraft. Water is forced under pressure to a pair of boots with jet nozzles underneath which provide thrust for the rider to fly up to 22 m (72 ft) in the air or to dive headlong through the water down as far as one is willing to go.

A jetboat is a boat propelled by a jet of water ejected from the back of the craft. Unlike a powerboat or motorboat that uses an external propeller in the water below or behind the boat, a jetboat draws the water from under the boat through an intake and into a pump-jet inside the boat, before expelling it through a nozzle at the stern.
On December 3, 1787, inventor James Rumsey demonstrated a water-jet propelled boat using a steam-powered pump to drive a stream of water from the stern. [6] [circular reference] This occurred on the Potomac River at Shepherdstown, Virginia (now West Virginia) before a crowd of witnesses including General Horatio Gates. The 50-foot long boat ...
There are five categories of Sea-Doo models: Recreation, Tow Sports, Touring, Sport Fishing, and Performance. [14]The Sea-Doo jet-powered sport boats included a four-seater Sportster 150 with 155 hp or 215 hp, a four-seater Speedster 150 with 255 hp, and a seven-seater Speedster 200 with 310 hp, and a Speedster 230 with space for up to twelve people.
Beriev Be-200 filling water tanks in the Mediterranean Sea while in operation during the 2010 Mount Carmel forest fire. The Beriev Be-200 Altair (Russian: Бериев Бе-200 «Альтаир») is a jet-powered amphibious flying boat of utility type designed and built by the Beriev Aircraft Company.
Moving water, river flow or strong tidal actions have posed the biggest danger to participants. When the jet ski and the floating rider move with the water, the 20+ meter long hose can hang up on underwater obstructions. This can pull the rider, and potentially the jet ski under water as the hose becomes taut.
