Counter rudder
Counter Rudder is the parameter that counteracts the eff ect
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 fi gures illustrate the eff ects of various
Counter Rudder settings.
