ABSTRACT:
The present invention provides a paddle boat having a hull and a closed loop flexible member which is rotatably mounted to the hull while a pedal assembly longitudinally drives the flexible member around its loop. A plurality of substantially planar paddles are pivotally mounted to the flexible member at spaced positions therealong. The paddles are pivotal between a first and a second position. In the first position, the paddles extend outwardly from the flexible member and propel the hull forwardly as the flexible member is driven by the pedal assembly. Conversely, in its second position, the paddles lie in planes substantially parallel to the direction of travel of the flexible member to permit free gliding of the boat. However, a locking assembly is associated with at least one paddle to lock the paddle in its first position when the flexible member is driven in the reverse direction.
