This is my second Profurl unit in as many boats . I found both units hard to furl , I am going to take a look at the bearings on my present set up , if I don't see any yuk in them I would have to say it's a design problem and a Harken
will be on my short list.
The only experience I have had with a Harken furler was on a 26 boat I had many years ago and the loads were no where near as high.
Other people I have talked to , who have had experience with both the Harken and Profurl say the the Harken is easier to furl under load .
