Industry Database

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.

Founded in 2012, Sharrow Engineering LLC is a nautical and aeronautical engineering company that is dedicated to the research and development of revolutionary high performance propulsion technologies for the maritime and aeronautical industries. Company offices are headquartered in Philadelphia, with additional offices in Detroit MI. Sharrow Engineering LLC has assembled a team of the world’s top aeronautical, nautical, aerospace, and mechanical engineers to assist with the company’s core mission to reinvent the methodologies and technologies used for propulsion in the 21st century.
