Abstract (en)
Improvements in oars of boats which consist of an oar with a toothed articulation (5, 6) which divides the oar into two parts (1, 2) in such a way that when the oarsman (3) bends his forearm and drives the part (1) backwards, the part (2) of the blade (4) is also driven backwards making the boat (10) move forwards, said articulation (5, 6) being mounted in a tilting way on the bulwark (12) so that pushing downwards the part (1) of the oar its blade (4) rises leaving the water to return to the initial position. <IMAGE>
