Abstract

The oar has a shaft (2) hinged at one end which is fitted with a toothed segment. This meshes with an equivalent one (3) on the handle (1). The pivots are assembled onto a plate which fits over the gunwales and is pinned into position. The blade (7) is free to rotate at the end of the boom, and has a peg (8) in the slot (9) to prevent backward rotation of the blade while still allowing feathering to take place. The boat is rowed by facing the direction of motion.
