Jet Board By Beluga Extreme is a type of water jetpack attached to a personal water craft (PWC) which supplies propulsion to drive the Jet board through air and water to perform a sport known as Jet boarding. A Jet board 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 (49 ft) in the air or to dive headlong through the water down to 2.5 m (8 ft).
