Click to enlarge

The SA 500, works independently of the main rudder, over an auxiliary rudder but also benefits from the vastly greater steering force delivered by the servo-pendulum mechanism.

Designed for. yachts with centre cockpit and wheel steering
yachts with an hydraulic wheel steering
yachts with aft cockpit and wheel steering
yachts that need a powerful windvane self steering gear and skippers wanting the very best steering performance.

The SA 500, can put the helm over 45 degrees. Double rudders are enormously efficient, as the system operates:
Without transmission lines,
The pendulum rudder and the auxiliary rudder are perfectly matched,
The auxiliary rudder has maximum leverage for turning the boat from its position off the stern and the main rudder can be locked in place to take care of weather helm.
