Ah ha. I understand. Concern with respect to the head foil can be an issue. Didn't have that worry on a J-24. I have roller furling (Pro Furl) on Nice Pear, and have not seen any issues. HOWEVER, it does raise some fodder for discussion with respect to the hank on jib discussion. In light air, on the J-24, (and it seems to work on the 30), the more headstay sag the better. Does this give the boat with the wire headstay an advantage?
