The sport of competitive rowing places great demands on both the rower and the equipment used. Rowing itself is a very equipment oriented activity, and there is currently much room for improvement. This project has been an attempt to correct the current situation of one of the most critical pieces of rowing equipement, the rowing rigger. This rigger is essentially an outrigger which supports the oar and provides the neccessary leverage to the rower. Current designs are expensive, overweight, unreliable, and difficult to use and adjust. The focus was thus to improve these features, especially the adjustability of the rigger, a source of great frustration to those using this equipment. In order to proceed in developing of a better rigger, much research and testing has been conducted on current designs. For this project, there was a principle focus on sweep rowing, although the final product could be applied to all types of rowing. This has included finite-element modeling and dynamic stress testing of an actual rigger. This test data has provided accurate and realistic operating conditions for analysis. Several initial concepts were generated and studied, and two were then identified for further refinement. After these concepts were refined and analyzed, a final concept was selected, and detailed design work commenced. The results of the design process have produced a unique final design. The most significant advantage of this design is the elimination of the top stay, which has proved to be source of frequent adjustment problems and highly prone to damage. In addition, one other stay was eliminated, and quick release devices were used to allow adjustment with a minimum of tools. The pitch adjustment relies on the use of Concept II oarlocks produced by Schoenbrod, which utilizes replaceable bushings. Lastly, the rigger allows all adjustments to be made independent of each other, a major concern in the design process.
