I installed a Raymarine auto pilot on Hibou. I don't remember the model number and it isn't listed on the Raymarine website. I should have spent the extra bucks and got the model with a gyro compass that can "learn" how the boat responds to the helm. As it is the one I have works....sometimes...when the stars and planets are aligned. ;-)

I just installed a Raymarine autopilot on my mariner 31. I got the rotary drive unit model. I have a ton of pictures and more details that I've been meaning to post. Now that you've asked, I'll really do it.

I got the unit without the gyro. I required a bit of messing around to find the right settings but now that I have, it works great. It steers like a champ even in choppy following seas.

I'll try to post more details in the next few days.

Would you care to share your settings for your auto-helm?

Hi Craig,

I can't remember all of the settings off the top of my head but I do remember that the rudder gain setting seemed to make the biggest difference. I ended up with it near the top of the range. I think it goes to 9 and I think mine is now set to 8. Before I did that it wouldn't stay on course with following seas. After I made that change we went around Point Conception with short period, eight foot following seas in 20 - 25 knot winds and the autopilot steered great. We motored through that but also sailed down wind on auto during other parts of the trip.

I think I also significantly increased the level of the autotrim. That lets the pilot apply more standing helm and seemed to make a big difference while we were under sail.

I won't get a chance to get down to the boat until next weekend. If you'd like, I can try to get the exact settings for you but I suspect they'll be a little different on everyone's boat and that you'll need to adjust them for different conditions. In that respect, the gyro-compass model would be nice but with enough manual tweaking mine seems to do pretty good.
