What jake said…

There was a guy on this forum, I want to say a year or two ago from NYC. He had a prindle 18 and cut down a backup main. I can’t remember the final outcome exactly, but what he was planning on having a small piece of very low stretch line attached between the ring and sail to make up the difference for the shorter sail. He then attached a small diameter line to the ring to allow him to be able to unhook the ring without too much trouble. If my memory serves me correctly he was very happy with the setup.
