Gorg027, I was faced with the same decision several years ago for my H-26. I carried my original 1994 mainsail to my local sail-maker to have him replace some web-sewn slugs. Before I spent any money on it, I asked him to inspect the sail condition. He spread the sail out and carefully inspected it. He told me my boltrope was shrunken and would affect my sail shape. He cut some stitches, stretched the boltrope, and told me it still had 65% life remaining on the sail, and it had a very good shape. I think he charged me only for the replacement of the sail slugs. All told, it was under $50. The bottom line, I think a TRUSTED sail-maker could tell you if you need a new sail. BrianW
