Awesome. I understand about weight. At 240#, I sail a modified Prindle 18-2 and am most of the crew weight. I had been taking the weight factor, but am going to just add 40# to the boat and get rid of one of the correction factors. I have also put a set of carbon sails on the boat which almost eliminates the downhaul use. I can pull a couple of inches and that is it... Most of the time, I don't bother with it at all.
