This is the third year I have had my hunter and the first time I have had a problem with the in mail furling. I noticed on a recent sail that the top of the mail sail was wringled aand could not be straigthen out. We went up the mast and pulled the sail out, but it went right back to the same situation. Our boat yard said that this was a design flaw with the furling rod and could not be corrected. Has anyone had this problem and found a solution?
