ABSTRACT:
A kayak paddle for increasing paddle stroke efficiency and for improving comfort in paddle handling has a pronounced bent blade to length design of the paddle blade, as compared with prior paddle blades. The paddle has two blades, one blade secured at its top end to each end of a paddle shaft with a longitudinal axis. The bottom end of each blade extends forward of and above the longitudinal axis of the shaft, such that the chord line between the bottom end and top end of the blade intersects the longitudinal axis. The blade's length to radius of its arc is greater than 12 to 1. Through slots can be provided in the blades for stabilization and to minimize flutter. In addition, the paddle shaft is ergonomically shaped to fit the user's hand.
