Niels
decisively answered the question I am often asked, "Can I use a DN rig
on my Icester", with a resounding, "NO!". At least, it did not work out
well for him. A DN sail is a full 8 square feet larger than the designed
Icester sail, and it's higher aspect ratio, cheater boom, and greater overall
efficiency combine to load the fuselage with a bit more force than it can
handle. The sides of #28 loosed themselves from the frames under some hard
going. He is going to repair the boat, and try out a smaller soft-water
boat rig, in an attempt to get in some more sailing in what's left of the
season.
