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. The Sharrow Propellerâ„¢ 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.
New boat propeller promises more speed, efficiency
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. Jan 14, 2019 Introducing the New High Efficiency Sharrow Propeller P hiladelphia design firm Sharrow Engineering, LLC announced that the company's propeller design has been awarded patents in the U.S., Japan, Canada, and European Union with further domestic and international patents pending. No problems. Over the course of two days, BoatTEST's captains tested a pair of Sharrow Marine props and a pair of Yamaha Saltwater Series II props on a World Cat 325 DC..

Sharrow and MIT have both been working on toroidal propellers which have shown incredible results.In this video we look at a new design of propellers known a. The Sharrow Propellerâ„¢ 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. 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? VEEM has over 50 years of experience in boat propeller design & manufacturing as well as cavitation resistance and variable pitch technology. Exclusive agreement signed with Sharrow for VEEM to commercialise revolutionary new propeller design October 2, 2023. Media. VEEM Marine x NautiStyles October 1, 2023. ASX Announcements Media. VEEM.

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. Advertisement High-tech propeller design aims to improve your boat's speed, economy and handling. By Capt. Vincent Daniello Updated: January 18, 2017 These Rolla surface-piercing props on Arneson drives, with half the prop and no running gear in the water, reduce drag by 50 percent. Twin Disc Rolla
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.

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 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.
