  • Ergonomically improved kayak paddle
    Patent number: 5820424
    Abstract: An ergonomically improved kayak paddle and a method for making the same is provided which improves the overall strength of the paddle while substantially reducing hand and arm fatigue for a user. The kayak paddle utilizes non-concentric gripping regions between a substantially longitudinal shaft and paddle blade sections. The gripping regions are interconnected to the shaft at non-abrupt predetermined angles of curvature and in a geometric configuration which reduces structural stress and fatigue at critical portions of the paddle while allowing a paddler to orient the paddle by touch alone.
