发明名称 Hydrofoil oar with movable outrigger
摘要 A rowing apparatus comprising, in combination: a boat having a hull with fore and aft ends and an outrigger frame movably mounted onto the hull and having opposite ends projecting laterally outwards from each side of the hull. The apparatus further includes 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 of the legs constituting a blade loom lying generally fore and aft to the boat hull at mid-stroke and having an outer end. A sweep hinge member is mounted onto each opposite end of the outrigger frame and is adapted to rotate about a substantially vertical axis, the sweep hinge member including an oarlock frame adapted to mate with the L shaped oarloom of one of the oars at about the elbow. A teeter hinge member is mounted to each oarlock frame and extends through the mating L shaped oarloom so as to permit rotation of the oarloom about a horizontal axis which is substantially coincident with a plane generally bisecting the right angle defined by the L shaped oarloom. 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 an angle with respect to the plane of the blade mounted to the oarloom on the opposite side of the hull.
