What is Rudder Gain?
Quick Tip
Boats can vary widely in their response to helm, and by adjusting the
rudder gain you can change the S1000's steering characteristics.
Rudder gain is a measure of how much helm the S1000 applies to
correct course errors – higher settings mean more rudder is applied.
This can be set in the range 1 to 9.
You will find it easier to recognize the steering
response in calm sea conditions

To determine if your rudder gain is appropriate, make a 40º turn in AUTO
mode
Gain is correct when you make a crisp turn followed by an overshoot of
no more than 5˚.
Gain is too high when you overshoot the turn by more than 5˚ and
there is a distinct ‘S’ in the course (A)
Gain is too low when the boat’s performance is sluggish and it takes a
long time to make a turn. There is also no overshoot (B)
