Am I too understand that the self-tacking jib takes no hit? Even though it is a smaller sail the ease of tacking with it makes me think some hit should apply. I planned to use the lower 67.6 which includes a .995 hit for the jib. Ding seems to think a 66.8. I looked into sail size early on and was told the Tiger main is smaller, I cut a foot off the TheMightyHobie18 boom and its still too long for the Tiger main. The mast is only 1.5' taller and this is the old ST main, not the STX.
