Rudder gain
Sets the rudder gain which is the ratio between the commanded angle and the heading error.
Too little rudder Set Course
Too much rudder
Set Course
• Too little Rudder gain and the autopilot fails to keep a steady course
• Too much Rudder gain gives unstable steering and reduces speed
• Low speed requires more rudder gainthan high speed

Counter rudder
Counter Rudder is the parameter that counteracts the effect of the boat’s turn rate and inertia.
For a short time period it is superimposed on the proportional rudder response caused by the
heading error. It may sometimes appear as if it tends to make the rudder move to the wrong
side (counter rudder).
The best way of checking the value of the Counter Rudder setting is when making turns. The
figures illustrate the effects of various Counter Rudder settings.
