SmartPilot Series 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, S2G and S3G systems will adjust the AutoTrim setting automatically dur-
ing the AutoLearn (see
page 31
)
• Non-G systems will require manual adjustment of AutoTrim (see
page 37
)
after the initial seatrial
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
excessive 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, S2G and S3G systems have a ‘FastTrim’ feature within AutoTrim. Select
AUTO TRIM OFF
to turn off FastTrim as well as AutoTrim.
