Rudder damping

If the SPX-5 Tiller system 'hunts' when trying to position the rudder, adjust the rudder
damping value to minimize this. Increasing the rudder damping value reduces
hunting. Increase the damping one level at a time until the autopilot stops hunting, and
always use the lowest acceptable value.

AutoTrim

The AutoTrim setting determines the rate at which the SPX-5 Tiller system applies
'standing helm' to correct for trim changes caused by varying wind loads on the sails
or superstructure.
The default AutoTrim is set as part of the AutoLearn process (see page 43 ).
If you need to change the setting, increase the AutoTrim one level at a time and use
the lowest acceptable value:
• If the SPX-5 Tiller system gives unstable course keeping or excessive drive
activity with a change in the heel angle, decrease the AutoTrim level.
• If the SPX-5 Tiller system reacts slowly to a heading change due to a change in the
heel angle, increase the AutoTrim level.
• If the AutoTrim level is too high, the boat will be less stable and snake around the
desired course.

Response level

This sets the default SPX-5 Tiller system response level setting. The response level
controls the relationship between course keeping accuracy and the amount of helm/
drive activity. You can make temporary changes to response during normal operation
(see your Operating Guide for details).
