Abstract:
A personal watercraft is disclosed comprising a pair of longitudinally connected pontoons suitable for supporting a user on the surface of a body of water. A slip-joint comprising a pair of concentric cylinders, one attached to each pontoon, provides desired lateral fixation between the pontoons while allowing relative longitudinal movement. Floating outriggers are provided to enhance the stability of the watercraft, and a set of hand rails helps the user balance on and operate the device. Paddle elements can be provided on the bottom surface of each pontoon to allow the user to operate the watercraft by using a striding motion similar to that used when cross-country skiing. The watercraft may have a rudder to help steer the craft, and it may also have a removable seat. A sail option is also provided. The pieces of the watercraft are removably connected to allow quick and easy assembly and disassembly, for transport to and from the water.
