Under Sail

Under Normal Sailing conditions, the Maxprop propellers posess a low drag shape. Compared to a folding propeller, the extra wetted surface of the Max-Prop blades is offset by the reduction of projected area: A.

In forward

The torque of the prop shaft acting on the "differential" type design will open the blades in unison to the pre-seat pitch at any throttle setting. This will provide maximum efficiency (96% of same size fixed prop) plus eliminates the vibration problems of a folding prop.

In reverse

As in forward, the torque of the shaft will rotate the blades, 180 degrees in less than 3/4 of a shaft rotation, presenting the same leading edge and pitch in reverse. This provides better directional control and 80% greater power than a comparable fixed blade propeller.

MAXPROP automatic feathering propellers come in three different types: the 2-blade, 3-blade, and new VP series.

These propellers offer much higher efficiency rates than normal collapsable propellers, almost the equivilent of a fixed pitch prop. Maxprop propellers are also available in saildrive units.

	2 Blade Classic available Diameter 280mm to 1120mm for shafts 19 to 65mm
	3 Blade Classic available diameter from 280mm to 1120mm for shafts 19 to 80mm
	3 Blade "VP" available diameter from 380mm to 915mm for shafts 25 to 55mm
