|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 emergency.
DRAG FREE SAILING- The high strength of the 2507 super duplex stainless steel blade allows a very thin design, symmetrical in section and virtually flat, resulting in minimal drag. This becomes most apparent in light winds, when it is most important. Typically sailing speed improvements of 10-15% are realised compared to a fixed blade propeller, as is an ability to point closer to the wind. Turbulence over the rudder is also reduced, giving an improved feel on the helm. Revised internal gearing and blade design means Autostream propellers stay feathered at sailing speeds in excess of 25knots, WITHOUT the need for a shaft locking brake.

|SAIL DRIVE MODEL
The Autostream saildrive feathering propeller has these additional features…
The Autostream propeller blades rotate automatically, presenting a very narrow edge to water flow under sail, drag is substantially reduced, dramatically improving performance under sail. Typically speed increases are over 10-15% compared to fixed blade propellers.
The reduced drag allows you to maintain a course closer to the wind, getting you to the finish line, the bar or your destination earlier.
Manoeuvre with Ease
Autostream propeller blades rotate 180 degrees when changing from forward to reverse, giving the same efficiency 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 efficient propulsion, without compromise to sailing speed.
Other benefits 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.
Independent 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 manoeuvring,
Autostream Propellers give you the “Best Bang for your Buck”
