Attorney, Agent or FirmInternational ClassB63H 016/20AbstractThe watercraft has a catamaran hull system with parallel rear pontoons pivoted for side to side oscillation from the trailing end of front pontoons. A rigid frame interconnects the front portions, and back support post is pivoted to both the frame and to linkage interconnecting the rear pontoons, so that the operator can lean to either side to pivot the back support post and turn the boat in the direction he is leaning. Bicycle pedals rotatably carried on the front of the operator support frame, drive a propeller to propel the boat, and the foot pedaling action may be augmented by lines secured to the pedals so the operator can pull each pedal manually on return.Field of SearchPlural-crank typeSliding handle or pedal Including gear means Lever with connecting linkage Having endless drive member Fluid pump Rocking watercraft Having flexible drive shaft Rotary cranking arm OPERATOR POWERED DRIVE FOR PROPELLING MEANS Having reciprocating pull cable Chain and sprocket STEERING MECHANISM Remote control steering excluding manual operation Having laterally disposed skids or pontoons Movably mounted hull portion or hull adjunct Pontoon structure Inflatable | |
