Yes, Peter. I had new sails built when I bought the boat. North Sails in Kemah, TX put 4 (I think)vertical battens about 5 ft. long in the leech. There is essentially no negative roach with the battens and as long as I'm careful about pulling the end of the boom down before furling there has been no problem binding. After three years, there's no evidence of wear on the sail at the battens. When Craig of SANGARIS and SSCA fame saw the new sails he commented on what a difference the battens make. ;I'd recommend that you add vertical battens if you have to buy new sails. Kent SM 243 KRISTY
