<p>A paddle of rigid unitary construction formed in plastics material, for use with boats consists of a hand-receiving portion forming one end-part of the paddle, a longitudinally extending generally planar blade portion of substantially greater length than width forming the other end-part and laterally spaced side members extending longitudinally from the blade portion into the hand-receiving portion. A rigid lateral hand-grip that is relatively narrow in the longitudinal direction spans the side members at a position longitudinally spaced from the blade portion between the ends of the paddle to define a first aperture between the side members, the blade portion and the hand-grip whereby a hand may be curled around the grip. A rigid lateral bracing portion spanning the ends of the side members remote from the blade portion in longitudinally spaced manner from the hand-grip to define a second aperture between the hand-grip, the bracing portion and the side members. Both the bracing portion and the hand-grip lie generally in the principal plane of the blade portion. In use with the fingers of one hand curled around the hand-grip, the hand extends through the second aperture with the lower arm bearing against the bracing portion to restrain the paddle against pivotal movement within the grip while the blade portion is subjected to pressure during propulsion.</p> |
