Dolby Family Ventures believes the Sharrow technology could transform an industry. “Sharrow Marine ushers in a new era of environmentally conscious boating with a design platform that results in higher performance and efficiency with lower fuel consumption. The Sharrow propeller offers safety, stability, improved planing, and displacement performance while reducing vibration, cavitation, and noise. The entire marine industry will benefit from these developments,” said David Dolby, CEO of Dolby Family Ventures.

Sharrow Engineering launched its first subsidiary company, Sharrow Marine LLC in 2020 and won the coveted 2020 Miami International Boat Show Innovation Award. Since then, Sharrow Engineering has made significant investments in manufacturing facilities just outside Detroit to meet the rapidly-expanding worldwide demand for the Sharrow Propeller and has plans to more than triple manufacturing output by early 2023.

“We couldn’t ask for a more ideal partner than Dolby Family Ventures," said Greg Sharrow, President, and CEO of Sharrow Engineering and Sharrow Marine. “The Dolby name is recognized worldwide as the visionary leader in sound enhancement and noise reduction for audio recordings, starting with music. And our propeller technology is based on a silent drone blade that I developed while working as an Executive Producer and Director in the video and music industry to capture enhanced drone shots where noise is a critical factor. Together, we will accelerate bringing the Sharrow Propeller technology to a much larger customer base through the marine industry and other propeller driven market segments.”
