We just have an O'Day 272. I wanted a new main and also ended up talking to Doyle Sails out of Marblehead, Mass. They were just excellent to deal with and will make you very glad you went with them. I ended up with a fully-battened main, with considerably more roach than our original sail had....I am NOT a fan of the extreme roach look so I just wanted more roach but not over-roached. The folks at Doyle made us a stack-pak main sail that just is excellent....It came with lazy jacks, fully battened as I said, and more roach. There has never been an issue with the roach getting caught on the backstay or topping lift.....I've just been very pleased. The sail is so much more powerful and is so easy to do it's almost embarrasing. Pat
