I'm a new member, but I've been a reader for several years There is some great advise on this board and I hope to add to it from time to time. My question is how do you determine what your correct sail number is? I'm in the process of putting a '86 Prindle 19 back on the water and the sails that came with the boat do not have a number. They are probably replacements. Can you tell from the ID number what it is? My number is SURE0142H86. Any help decoding it would be appreciated. The local club (and most others)needs a number for their races. Thanks
