Im filling out my rating form and have been going over the dimension on the web site and comparing them to the phrf definitions,  some things dont match up, help please if you know:  SGF (Spinnaker foot lenght from tack to clew) assuming the 27.9 listed on our site is the foot and not the leach, shouldnt leach be the same as the luff 49.5? How about SGM (Spinnaker mid girth),  Also arent the I and ISP on our boats the same?  thanks.
