I have a question about main sails. I have a radial cut pentex main, but I noticed that there was not a single radial cut main at the NA's. I looked at the rules and there does not seem to be a restriction on how the sail is cut, just material. Is this correct? If so then have people found there is no advantage to a radial cut main?
