ABSTRACT:
A personal watercraft having a pair of pedal-driven impellers. The watercraft includes an inflatable frame having substantially planar fore and aft portions which are slightly offset from each other. The fore frame portion includes a substantially planar support receiving the upper body of a user thereon. A drive shaft is mounted on the aft frame portion and has offset portions on which pedals are mounted for receiving the feet of the user. The impellers for generating thrust are rotatably connected to the drive shaft and are mounted on the aft portion of the frame. Accordingly, pedaled rotation of the drive shaft causes the impellers to generate thrust for pedalling the watercraft in the desired direction.
