I have just installed a roller furler (CDI) for the jib, and I was wondering how much headstay sag is acceptable. Beating to windward the rig sags off to leward about ten inches or more. My mast is bent aft from the upper spreaders to keep the main flat, so there is plenty of tension on the headstay. I suspect that some is inevetable, but I would like to hear from those of you who are sailing with furlers. Thanks in advance, david
