Philadelphia based design firm Sharrow Engineering has received patents in the USA, Japan, Canada and the EU for its propeller design that promises to increase efficiency between nine and fifteen per cent.
This propeller design developed by Sharrow Engineering provides a wider peak efficiency curve for greater utility over a wide scope of operational ranges and claims a seventeen per cent reduction in torque whilst accelerating.
Third Party Validation
The propeller has been in development for over six years and has been subjected to an in-water test programme using manned vessels in lakes, rivers and bays. The design has also been validated through independent third party computational analysis. Test results showed the propeller being between nine and fifteen per cent more efficient than the industry standard Wageningen B-series design.
Available in All Traditional Alloys and Materials
The Sharrow Propeller can be manufactured in all traditional propeller alloys and materials, matching any size and blade configuration and retrofit without engineering challenges. The propeller is claimed to be suitable for among others cargo ships, tankers, workboats, and recreational craft.
