What is Rudder Gain?
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.
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)
