Abstract

See full text

A collapsible blade equipped paddle device enabling an underwater return stroke includes a shaft, which has a blade engaged to a first end thereof. The blade comprises a frame having a panel engaged thereto and extending therebetween. The frame is selectively collapsible so that the blade assumes an open cupped configuration when a forward stroke is applied to the shaft and a collapsed configuration when an underwater return stroke is applied to the shaft. The blade provides thrust to a marine vessel during the forward stroke and minimal resistance during the underwater return stroke.
