Sharrow Props

Fisherman's Report on Sharrow Props After 1 Year/400 Hours at Sea

The Duckworth 30 XL has a 9’6” (2.9 m) beam, 44” (111.8 cm) topsides and weighs 7,140 lbs. (3,239 kg) dry.  Her deadrise at the bow is 39 degrees and 19 degrees at the transom.  She is intended for offshore work at moderate speeds when powered by twin 300-hp Yamaha engines. Her cabin is forward, allowing maximum space in the cockpit for working fish with several anglers aboard or hauling crab pots aboard.

The Sharrow props are an ideal propulsion system to help this vessel perform better than she could ever do with conventional wheels. At 3000 RPM, Yamaha reports that with 15.75 x 15 conventional props, the boat — with one person aboard and full fuel — attained 13.5 mph at 3000 RPM, went 21.5 mph at 3500 RPM and 25.5 mph at 4000 RPM.

With Sharrow props on the twin 300s, 6 people aboard and a full fuel load during our test, we recorded: 3000 RPM — 17.6 mph; 3500 RPM — 24.5 mph; 4000 RPM — 30 mph.  These are big differences and this dichotomy between the two prop designed is why the owner of this Duckworth 30 XL is such a fan of Sharrow props.
