Servo-Auxiliary Concept

Most auxiliary rudder systems like the South Atlantic S 500 or S 600 on the market are servo-driven – meaning they employ a servo rudder to drive the auxiliary rudder. Instead of lines to the boat’s wheel/tiller to drive the main rudder, there are connected to the unit’s auxiliary rudder. The servo-auxiliary systems are directly steering the boat with their auxiliary rudders.

Advantages

The South Atlantic S 500 or S 600 main advantages:

  • Less complex – does not increase overall length as much. It is possible to remove the servo unit in seconds
  • Ability to remove South Atlantic rudder – servo-auxiliary rudder Lift up
  • Ability to install off center - The same physic laws apply to every system in the hole market-
  • 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.

Self Steering Wind Vane S - 500

south atlantic self steering S 500

Description.
when a servo pendulum self-steering wind-vane like the S 440 can´t fit the requirements of a given sailboat (Hydraulic rudder gear, very big force needed to turn the rudder, etc), auxiliary rudder systems are the way to go.

 

how does our wind vane work

Our Windvane Self Steering : S 500. The S 500 consist of a servo pendulum rudder mounted directly to an auxiliary rudder which is part of the self-steering system. The main rudder then is used to "trim" the main course and the self-steering gear steers "around" that main course according to the changes of the apparent wind.
