Joe, I asked Les Homan how much he used on his red XL and he said he used a little less than 24 yards so that is what I ordered. I have not covered mine yet though. I can't tell you for sure if that is enough. The 60 inch width looks like it will be plenty wide enough for overlaps. My wing came out to 54 and 1/2 inches front to back. The peelply is not certified in the 1.8 oz dacron.
