tillerpilots

Greetings- I currently have an Autohelm ST2000 tillerpilot for my 32'' Nicholson. It does well in most conditions, but with lots of wind or current it struggles(especially with quartering current on the rudder). I would like to keep this unit as a backup, and possibly upgrade to a stronger autopilot. Any opinions on the ST4000 vs a Simrad 30 model? The Simrad is much less expensive. Is there a reason for the big difference?

I have the Simrad 30 and am disappointed with its performance. I also had the 4000 for a while and did not like it either. I can get things to work when motoring, but under sail is a different story.

Quartering seas are a challenge to steer by hand, let alone for an autopilot. Do you ever trim while the pilot is engaged? I have found trimming to the pilot both fun and beneficial to the autopilot.

Yes, I have found that it does definitely help to trim. I have been pleased with the 2000 so far(about 4000 miles), but the times where it is beginning to be overpowered worry me. Any other opinions on the 4000 vs the Simrad 30?

To maintain a course in quartering seas, you must anticipate each wave and start correcting before the stern is driven sideways. No compass driven auto steerer is going to do that for you. I''ve had three Autohelms. Two worked fine, one was completely unpredictable for the first five or ten minutes, so I would turn it on and leave it disengaged til it got its groove.
