…Over the past six years, Sharrow Engineering has analyzed extensive testing data 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. The research demonstrated that the Sharrow Propeller is 9-15 percent more efficient than the industry standard Wageningen B-series design.
