¼ Note: There is no configuration when using an SG05 PRO. No Rudder- or Feedback calibration
is required.
Advanced rudder settings
Minimum rudder
Some boats may have a tendency of not responding to small rudder commands around the
course keeping position because of a small rudder, a rudder deadband, whirls/disturbance of
the water-stream passing the rudder or it is a single nozzle water jet boat.
By manually adjusting the minimum rudder function, the course keeping performance might
be improved on some boats. This will however increase the rudder activity.
¼ Note: Only set a value for minimum rudder if it proves to give a better course keeping
performance in calm sea. It should be set after the autotune has been performed and a fine
tuning of the rudder parameter.
Rudder deadband
Prevents the rudder from hunting caused by high rudder speed and/or overshoot in the
steering gear.
Deadband mode
Auto or Manual (default: Auto).
• Auto: The rudder deadband is adaptive and is continuously operative. It will also optimize the
deadband to the speed of the vessel and the pressure on the rudder.
• Manual: If the Auto setting doesn’t perform properly due to extreme rudder speed and/or
overshoot, it can be adjusted manually.
Find the lowest possible value that will prevent the rudder from continuous hunting. A wide
deadband will cause inaccurate steering. It is recommended to check rudder stability in AUTO
mode at cruising speed to get pressure on the rudder. (Slight hunting observed dockside may
disappear at cruising speed.)
Range: 0,1 – 4 (default: 0,5)
