Sharrow Marine is a nautical engineering and manufacturing company that produces and sells the Sharrow Propeller, a groundbreaking advancement in marine propulsion technology. The company is a subsidiary of Sharrow Engineering, LLC, and is headquartered in the greater Detroit, Michigan area.
The core of the business is the Sharrow Propeller, invented by Greg Sharrow. It is recognized as a significant evolution in propeller design since the 1830s. The unique, patented loop-shaped design addresses and resolves the issue of blade tip vortices, which are a primary cause of energy loss and noise in conventional propellers. By eliminating or significantly reducing tip vortices, the Sharrow Propeller offers substantial performance improvements. Boaters can experience up to 30% greater fuel efficiency, which also translates to an increased range. The design also provides superior handling, particularly at low speeds, and a notable reduction in vibration and noise, creating a more pleasant and quieter boating experience. It is manufactured in the USA using high-strength, CNC-machined stainless-steel alloy and is designed to fit most outboard and sterndrive motors.
Founded in 2012 by Greg Sharrow, a Berklee College of Music graduate, the initial concept for the propeller arose from a completely different field. While working on a project to develop a quiet drone for film and recording purposes, Sharrow used a supercomputer to analyze and model drone blade designs. This research led him to discover the inefficiencies caused by tip vortices and ultimately to the creation of the toroidal, or loop-shaped, propeller design. This accidental discovery was then adapted for marine applications. Sharrow Engineering, the parent company, holds over 100 patents worldwide for this technology.
The company's business model revolves around the direct manufacturing and sales of these premium propellers to the maritime industry. Their target market includes recreational boaters and commercial vessel operators who are looking for enhanced performance, fuel savings, and a better overall on-water experience. The propellers are available for a wide range of boat and engine combinations.
