I had a profurl unit on a previous monohull
. When it worked, it was great. When it didn't.....
Main problem is precisely lining up the bolt rope
in the luff with the track on the mast
. This is not easy. Raising the main was the bigger problem. Getting it down was less of an issue. I never sailed it with a reef. But I always wondered how good the reef would be without an outhaul
,to tension the foot of the sail (when partially rolled).
Hard to say exactly but I'd sat it worked as it should about 60% of the time. Lazy jacks seem easier and more reliable.
