Abstract: An oar or scull is attached to the racing shell with an assembly that assures all motions required for rowing and restricts others. Over squaring and over feathering of the blade is prevented using stops which also provide positive feedback of blade orientation to the athlete and eliminate oarlock slap and rattle. Pulling on the oar handle inboard approximately 0.2 inches prior to squaring or feathering the blade moves the oarshaft outboard or inboard respectively, changing the leverage or load, at the completion of squaring or feathering. Normal rowing at the selected load is maintained with a steady outboard force of the oar handle. The oarlock is situated on the bow side of the vertical pin pulling the pin toward the bow during the propulsive phase of the rowing stroke. The vertical pin is supported by rigging which extends from the top and bottom of the vertical pin toward the stern.

Abstract: An oarlock (26) for a rowing shell (42) is threaded onto an adjusting tube (10) longer than the oarlock and just shorter than an oarlock pin (16). This oarlock/tube assembly is slipped over the pin and secured so that it is free to pivot. The pin is attached to a sill (28) of a rigger (32). Manual turning of the tube will raise or lower the oarlock without disassembly to make adjustment for height and weight of rowers or changing water conditions.

Abstract: An oarlock for a rowing shell has an elongated housing with a screw member secured therewithin for rotational movement, but not axial movement therewithin. At least one guide member is secured within an elongated slot member and is threadedly secured to the screw member, such that rotation of the screw will cause responsive movement of the guide member or members within the slot or slots. By rotatably securing the oarlock either below a sole guide member or between the guide members around the exterior of the housing, rotation of the screw will effect translational movement of the oarlock pin to facilitate desired adjustment thereof. A manually rotatable adjustment element permits rotation of the screw while the rowing shell is in the water to thereby permit adjustment to the rowing conditions, such as the weight and size of the rower and water conditions. A rigging has struts securing the rigger to the rowing shell and the oarlock rotatably secured to the oarlock pin of the present invention.

Abstract: A rowing apparatus having support tubing that extends over the gunnels of the canoe, and to which the oars are mounted, is angled upwardly to provide added clearance in choppy waters. The elongated track support to which the seat and the support tubing are mounted is provided with repositionable mounting brackets that enable the height from the floor of the elongated support member to be adjusted within a range of several inches to maintain a suitable center of gravity for a wide range of weather conditions. In this manner the rower is capable of maximizing the transfer of power through the rowing apparatus, and still maintain the stability of the canoe. Since wilderness rowing is a physically demanding activity, the rowing apparatus is easily adaptable for use as a training device, permitting the user of the apparatus to use the same device in their home for exercise and training purposes that they can also use in their canoe on an actual wilderness rowing expedition.
