South Atlantic S 440

It is a servo-pendulum windvane. It is the most widely proven principle for a windvane. This principle offers a great sensitivity-strength balance.

The windvane is a fast and efficient steering system. The servo-pendulum system consists of a [sensor-vane] which transmits the change in the wind direction to the windvane rudder. This moves laterally on reception of the signal. The rudder is attached to the tiller by [lines] which move the tiller or wheel that steer the sail boat.
