I am having some difficulty with the in mast furling main on my 2004 B331. 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. Are those of you with similar size beneteaus using the winch to furl and unfurl the main or are you able to do it by had?
