J Prop: the self-retracting variable pitch propeller

The most important feature of all J Props is the ability to position the blades while under sail. This happens in a very easy and quick way.

The effect of this characteristic is to minimize the resistance to the forward motion of the boat, allowing those who sail to increase in speed. For the same reason, the shaft and, consequently, the engine are not dragged into rotation by the movement of the propeller in water as occurs with fixed blade propellers.

Moreover, in motorized navigation – when switching from forward to reverse – the J Prop automatically invert the pitch. This allows you to have the same thrust in both positions and, therefore, to have better manoeuvrability in reverse, which can also be valuable on vintage boats.
