A Flyboard is a type of water jetpack attached to a personal water craft (PWC) which supplies propulsion to drive the Flyboard through air and water to perform a sport known as flyboarding. 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 metres in the air or to dive headlong through the water.
