How Does our Wind vane Self Steering Work?

The servo-pendulum system consists of a [sensor-vane] which transmits the change in the wind direction to the wind-vane rudder. The steering force of the servo oar is transmitted to the main rudder by two lines. The rudder is attached to the tiller by [lines] which move the tiller or wheel that steer the sail boat.
