Amazing Flyboard Power is controlled by a throttle on the PWC

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 (49 ft) in the air or to dive headlong
through the water down to 2.5 m
The first Flyboard World Championships took place in Doha, Qatar in October 2012
