Abstract

Such comprise inverting the working position of the rowlock, so that the oar (9) works on the side branch (7) of the same, opposite the hinge branch (6) on the shaft associated to the bearing structure (1-2) so that the thole-pin for such oar (9) is displaced sideways and considerably with regard to the thole-pin of the rowlock, and therefore with the oarsman's strength, oar length and rowlock bearing structure unchanged, the leverage increases and hence so does the force exerted by the oar stroke.
