A Flyboard is a brand of hydroflighting device which supplies propulsion to drive the Flyboard into the air to perform a sport known as hydroflying.

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 15 m in the air or to dive headlong through the water down to 2.5 m
