hi, i have a two part quetion. i remeber when i sea trialed my hunter roller furling main the previous owner always kept main centered and let outhaul create sail shape. just for fun i tried sailing this way and it does work. no gybing of boom. was this in any way correct? if heeling in 20 knot winds then just let boom out.2nd quetion. what would cause clutch (exterior arm) on raymarine 4000+ auto pilot to occasionally snap into off position?has done this in only 10 knot winds. thanks alan

My two cents
1. Yes, that's fine to let out the foot. But bear in mind that it does so in a rounded fashion which could mitigate the sail plan. As you suggest, let the boom out instead in heavier wind to keep the mainsail flat. 2. Perhaps too much wind disables the autohelm. I don't have one.

On the 4000+
I have no experience with a furling main...sorry. But I do have a 4000+... There two things to try first, both of which require an Allen wrench (may be metric, can't remember for sure) of the appropriate size. There is a machine screw in the center of the lever that also holds an adjusting cam. On mine, the screw backed out slightly and loosened the clutch just enough to cause the same symptoms without being obvious. Tightening the screw fixed the problem for me. If that is not the problem, the clutch may need adjusting. This is done by loosening the same screw turning the disk (clockwise...I think, but don't hold me to that...it's been a couple of years since I had to mess with it and I am suffering from chronic CRS). The clutch is designed to release under pressure to avoid burning out the motor. There is a section on this in the owners' manual. If yours is gone, you can download it from the Raymarine Support website.
