Worldwide patents for Sharrow Propeller
The Sharrow Propeller design, that its US inventors claim increases efficiency 9-15 percent, now has 20 worldwide patents.
Over the past 6 years, Sharrow Engineering has analysed extensive testing data for the performance of its propeller collected at the University of Michigan’s Marine Hydrodynamics Laboratory and implemented a rigorous in-water test program using manned vessels in lakes, rivers, and bays. Results from this comprehensive research program demonstrate that the Sharrow Propeller is 9%-15% more efficient than the industry standard Wageningen B-series design. Industry experts have traditionally evaluated gains of 1 percent efficiency as meaningful.
