What is Counter Rudder?
Quick Tip
You will find it easier to recognize the steering
response in calm sea conditions
Counter rudder is the amount of rudder your S1000 applies to try to
prevent the boat from veering off course. Higher counter rudder
settings result in more rudder being applied. This can be set in the
range 1 to 9.

To determine if your counter rudder setting is appropriate, make a 90º turn
in AUTO mode
Counter Rudder is correct when you make a a smooth continuous
turn with minimal overshoot.
Counter Rudder is too high when the boat ‘fights’ the turn and
makes a series of short, sharp turns resulting in a very ‘mechanical’ feel as
the boat changes course
Counter Rudder is too low when the boat overshoots the turn.
