The vane spins at right angles to the ground and can lock to the trim tab in any desired position, as the boat falls off the wind the vane will be turned by the wind and will take the trim tab with it which in turn causes the rudder to move in the opposite direction and thus corrects course. This design causes the side with the larger surface area to be blown away from the wind while the side with the smaller surface area points in the direction of the wind.
