I have found a Genoa set up for a CDI furler. The luff length seems to be correct at 23ft 9inches, but the foot is 16ft 2 inches. Will this work well on a 22 ft boat? I have already bought it I think. I just wanted to know so if it would not work, I would go ahead and resell the genoa.I see genoas referred to as genoas, 110 genoas, 120 genoas and 150 genoas. What exactly does that mean, and what size would be the one I have found?
