I am having some difficulty with the z spar in mast furling main on my 2004 Beneteau 331. The sail is fairly difficult to furl and unfurl. I usually need to use the winch. Not impossible by hand but extremely difficult. I lossen the main sheet and vang as suggested, but this only helps a little. I do not beleive I had this much difficulty when the boat was new --although by the end of last seaon the problem was evident. Does this sound normal or should i be able to furl and unfurl w/o a winch?
