A boat propeller is usually designed with two to five blades (though sometimes more). In the first instance, the number of blades is decided by the weight of the vessel: the greater the weight, the greater the blade area required to push it through the water with a minimum of slip and cavitation.


New boat propeller promises more speed, efficiency

The Sharrow Propeller™ is a remarkable new, patented loop propeller design that CEO and inventor, Greg Sharrow, claims can out-perform conventional propellers in most major parameters of current propeller measurement. The propeller was developed over 7+ years by Sharrow Marine, a Philadelphia-based nautical and aeronautical design firm.

1. Optimize the Number of Blades A lesser amount of blades tends to equal a higher theoretical efficiency while a larger number increases the propulsion. As blades are added to the design, they increase the amount of drag but improve the ability to move water, resulting in a smoother (and less vibrational) motion.
