I lucked out and was given a set of sails for a 18'hobie. I cut the bottom off where the normal 16 would be reefed. I resewed in a rope. It is a little narrower than the normal 16. I'm going to give it a try in a couple of weeks. I also got the boom from the 18 and will try it on the 16. It is a loose foot with internal out haul.
