Abstract
A strong, lightweight paddle for manually propelling a water craft with increased stroke efficiency comprises a cupped-shaped blade formed of a foam injected plastic, the blade being angularly displaced from the shaft of the paddle, the shaft is hollow and formed of a lightweight metal such as aluminum or a foam injected plastic. The shaft which is of a hexagonal shape includes a T-shaped handle member. The shape and construction of the paddle enables the paddle to be made shorter than conventional paddles but enables the paddle to maintain and even increase stroke efficiency.
