Is there any point of sail where you feel the wheel is responding in a normal manner.
Have you tried tacking or jybing with the auto helm to see if that works.
Does the boat steer OK under motor
only, in the forward direction at full RPM
speeds. ie 7 to 8 knots.
"don't know if it makes a difference that the configuration is that of the rudder
is in front of the sail drive"
The only time this may
make any difference is when under motor
, where the sail drive is in relation to rudder makes ZERO difference when under sail.
