44 SmartPilot Verado Installation and Commissioning Guide
Rudder damping
Adjust the rudder damping value if the SmartPilot ‘hunts’ when trying to position the rudder.
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 SmartPilot applies ‘standing helm’ to
correct for trim changes caused by varying wind loads on the sails or superstructure.
The default AutoTrim is set during commissioning:
• S1G systems will adjust the AutoTrim setting automatically during the AutoLearn
If you need to change the setting, increase the AutoTrim one level at a time and use the
lowest acceptable value:
• decrease the AutoTrim level if the SmartPilot gives unstable course keeping or exces-
sive drive activity with a change in the heel angle
• increase the AutoTrim level if the SmartPilot reacts slowly to a heading change due to
a change in the heel angle
• if the AutoTrim level is too high, the boat will be less stable and snake around the
desired course
Note:
S1G systems have a ‘FastTrim’ feature within AutoTrim. Select
AUTO TRIM OFF
to turn off FastT-
rim as well as AutoTrim.
Response level
This sets the default SmartPilot 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
SmartPilot Controller
Operating Guide
).
