Autostream Self Feathering Propellers

Sail Faster The Autostream propeller blades rotate automatically, presenting a very narrow edge to water ow under sail, drag is substantially reduced, dramatically improving performance under sail. Typically speed increases are over 10-15% compared to xed blade propellers. Point Higher The reduced drag allows you to maintain a course closer to the wind, getting you to the nish line, the bar or your destination earlier. Maneuver with Ease Autostream propeller blades rotate 180 degrees when changing from forward to reverse, giving the same efciency in both directions. Reverse acceleration is faster leading to less ‘prop walk’ and giving YOU full control over which direction you head, not the propeller. The large blade area gives powerful efcient propulsion, without compromise to sailing speed. Other benets include: A better “feel” on the helm due to less turbulence over the rudder. No need for the expense & complication of a shaft brake. Reduced noise and gearbox wear associated with a rotating prop & shaft. Independant forward & reverse pitch adjustment, set forward for cruising and reverse for thrust / control. When it comes to overall improvement to a sailboat, both sailing and maneuvring, Autostream Propellers give you the “Best Bang for your Buck” Australia Pty Ltd 41 London Drive Bayswater, Vic, 3153, Australia TEL: +61 (3) 9761 1633 FAX: +61 (3) 9761 0727 www.seahawk.com.au info@seahawk.com.au

FORWARD THRUST- Large blade area, coupled with the ability to easily adjust the pitch, allows 'fine tuning' to achieve optimum performance & fuel consumption, comparable to a fixed blade propeller. Able to be assembled in either a right or left hand configuration, and with simple pitch adjustment the same propeller can often be used should a future driveline or engine change require a different propeller setup. It is even possible to change rotation of the propeller in the water, should forward gear fail, allowing reverse to get you home in an SI - SHAFT DRIVE MODEL REVERSE THRUST-As...
