Abstract:
A manually-operable reciprocating rowing system having a reversible oar for forward or reverse propulsion. The oar has a plurality of pivoting blades mounted in a housing and movable between open and closed positions with each stroke of the oar. In the open position, the blades are positioned to allow water passage through the housing, while in the closed position, the blades are positioned to obstruct water passage through the housing. Gates are provided for stopping the pivoting movement of the blade at the blade housing. A reversing mechanism selectively pivots the gates to allow the blades to pass from one side to an opposite side of the housing, thereby allowing propulsion in a reversed direction.
