When I set the max rudder angle using setup the acu used the larger angle which made the starboard side vulnerable.
Hope this makes sense
I have cut the bolt just short of the locknut to equalise the angles and reset maximum rudder angle so it is well clear of the rudder stops.
Hopefully, I will have no more problems
Took the boat out today and all seems fine.
Thanks for your help.

You should be able to set the AP max turn to less than the rudder stops. Example, if max rudder is 42 degrees one direction, 35 degrees the other direction, set the max angle on the AP to 30 degrees.

Re: Raymarine Linear drive type 1 not disengaging after a hard night

It would be unusual for the AP to drive the rudder to the stops. Most likely, the normal steering range manually took the drive to its max end limits. This drive can only take 35* travel, so check to make sure you are not exceeding this - both on the ram and the stops.

Sailing downwind in 30 knot winds can put significant loads on autopilots. Following seas round the boat up and the autopilot tries its hardest to bring you back on course. You probably won't have this issue beam and close reaching.
