A rowing apparatus comprising, in combination: a boat having a hull with fore and aft ends and having an outrigger projecting laterally outwards from each side of the hull and at least two oars located one on each side of the hull, each of the oars comprising an L shaped oarloom including two legs joined at an elbow, one of the legs constituting a handle loom having a generally athwartship position at mid-stroke and the other leg constituting a blade loom laying generally fore and aft to the boat hull at mid-stroke and having an outer end. A blade having a hydrofoil shaped surface is mounted to and below the outer end of each blade loom, the blade lying in a generally vertical plane which at mid-stroke is located at a divergent angle with respect to the plane of the blade mounted to the oarloom on the opposite side of the hull.
The rowing apparatus further includes a seat for the oarsman which is movably mounted to the hull and foot restraints for securing the feet of the oarsman. The seat may be located either behind the handle loom with the oarsman facing forwards toward the fore end of the hull or ahead of the handle loom with the oarsman facing rearwards toward the aft end of the hull.
