THE SERVO PENDULUM WINDVANE CONCEPT
A servo pendulum system pulls a line that is attached to the steering wheel or tiller. In order to steer over the boat’s main rudder to bring the boat back on course. The servo pendulum system has a wind sensor, the pendulum includes a blade or paddle. This blade swing from side to side in the water, like a pendulum, directed by its wind vane sensor. As the boat falls off course, the wind angle changes and the vane is pushed over.
The movement of the vane rotates the shaft of the servo blade. Once moved from its neutral position, the flow of the water pushes the blade to one side with force. This movement pulls the connecting line to turn the wheel or tiller so the main rudder moves to bring the boat back on course. Once on course, the vane flops back to vertical/neutral and the servo blade reverts to trailing in the wake. A servo system pulls a line, which moves the wheel or tiller of the sailboat, a very efficient way to do the job better than us!.
Self Steering Wind Vane
South Atlantic Self Steering Wind Vane S 301 This is our S 301 Wind Vane Self Steering Gear for small Sailboats. It is a servo-pendulum wind vane, the most widely proven principle for a windvane. This principle offers a great sensitivity-strength balance and is lightweight.
Our wind vane is a fast and efficient steering system, your best sailing crewmember at sea!. 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
