Abstract
A rowing apparatus which allows an oarsman to face forward while propelling a watercraft such as a canoe (20) forward when pulling on handles (32). The articulated apparatus includes two sheaves coupled by a pair of criss-crossing, adjustable cables enclosed within a housing (24). A detachable, obtuse-angle shaped handle (32) attaches to a handle lever (34), which attaches to an upper side of one of the sheaves. An under side of the other sheave attaches to an oar blade lever (38), which extends to an oar blade (40). Each sheave has an axle (120) supported at its extremities by housing (24) and a canopy (26). A canopy cover (28) encloses each canopy (26), fastens to each axle (120), and rotates with its respective lever (34) or (38). A pair of outriggers (30A) and (30B) pivotally support housing (24) at an outboard location and attach to a pair of thwarts (46) and (48). A pair of webbing straps (50) form an "X" brace between thwarts (46) and (48). Mounting pads (54), which attach with an adhesive to the upper surface of gunwales (22), accept anti-slip pins (56) projecting from the bottom side of thwarts (46) and (48). Counterbalance springs (182A) and (182B) compensate for imbalanc…
