Which Autohelm Unit is this? I have recently installed an ST 4000+MK2.
As long as we are on this topic, is it normal for the Raymarine fluxgate
compass to constantly vary its reported heading +/- 3 degrees from the
magnetic compass heading even when the boat is tied securely to a wall in
calm conditions with no moving, rolling, pitching or yawing. No one is down
below moving large iron masses, the engine is not running and all other
electrical or electronic equipment is off.
If this message is too far off topic, I apologize.

Autohelms can do this - they can steer with an accuracy that seems beyond
any mortal. We have found the best way to steer downwind flying a
spinnaker, or with the headsail out on the end of a whisker pole on the
side opposite the main (goosewinged) is with one person not at the helm but
with a finger poised over the unit feeding in one degree correction changes
as necessary.
