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.

And, the noise of boat propellers also disturbs, and can even harm, marine life. Now, Sharrow Marine has created the Sharrow Propeller, which helps increase speed and efficiency, produces less noise and vibration, and enables greater control of the vessel while docking and superior handling of tight turns even at high speeds.

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.


New boat propeller promises more speed, efficiency

The Sharrow Propeller™ offers a faster, quieter, and more fuel efficient ride through state-of-the-art design that is custom machined and fitted to every boat. Two-time award winner and the first major advancement in propeller technology since the 1830s.

The idea behind propelling any vessel at sea is chiefly because of two reasons: 1. Manoeuvrability and variation of speed 2. Overcoming the resistance encountered by the vessel at sea Resistance, as we are aware of is a principal phenomenon inevitable in all bodies floating in real fluids.

A radical new toroidal boat propeller is being touted as the single biggest advance in propeller design since the 1930s. Claimed to deliver significant fuel savings across all different types and sizes of craft as well as faster planing, higher top speeds, superior handling and reduced vibration, it sounds almost too good to be true.

New propellers probably won't increase his cruising speed beyond its current 18 knots, but today's propeller designs better match individual boats and engines and improve fuel economy, run more smoothly and quietly, increase performance in the mid-rpm range, and even reduce the need for trim tabs.

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.

The new Wärtsilä propeller design is considered an energy-saving technology reducing also emissions and improving CII rating. A new propeller design, along with reduced vessel speeds and engine power, can lead to propulsive efficiency improvements of up to 15%. Redesigning the propeller can lead to significant efficiency gains for vessels.

Basic Boat Propeller Design. Understanding the basics of boat propeller design can help ensure that boaters get the most out of their engines and boats. The shape of a boat propeller is typically composed of two or more blades connected to a hub at its center. The number, size, pitch and cup (or rake) angle all contribute to how efficiently it.

At the 2020 Miami International Boat Show, Philadelphia-based Sharrow Marine introduced the culmination of a seven-year research and development project called the MX-1 Sharrow Propeller. Unlike every prop that's come before it, rather than blades, the MX-1 has loops of metal attached to the hub. How does this change the dynamic?
