Other forms: hydroflights
Hydroflight is a water sport: A person rides above the water on a device that is powered by a stream of water from a hose attached to a small watercraft.
The hydro- part of this word means "water," and that makes sense, as hydroflight is basically using water to take flight. Jets of water lift and propel the rider through the air on one of several types of hydroflight devices, such as boards, bikes, and packs that go on your back. Riders can control their height and direction with their body movements. There are even hydroflight competitions in which riders do advanced and daring maneuvers, like flips, spins, and dives.
