I bought an Intensity Radial sail and am having trouble with it. In light to medium air, I can't get rid of the lump of cloth behind the luff that runs vertically on the entire height of the sail. I think this is a factor of the extra cloth weight and extra resin in the sail, making it stiffer, and I've seen it on a full sized Intensity sail, as well. Normally, one could adjust the outhaul to pull this "lump" out, but it doesn't work with this sail. The mast sleeve is also wider than on my legal sail and I don't know if this is a factor in the sloppiness of the sail. Can anyone who has an Intensity sail guide me? Is there a way to flatten this sail?
