Hi Jim, You have two choices. You can have a small amount of leech from head to clew cut out of the sail in a crescent shape so that the unsupported material that is fluttering is removed (this is called leech hollow by sailmakers) or you can use battens to support the leech that are oriented parallel to the luff so that they line up when the sail is furled. They must be parallel, though so that the battens due not twist and deform when they are furled. They also need to be longer than the previous battens to get into the body of the sail that provides the support they need for the leech. Any sailmaker should be able to do either of these jobs for you for a reasonable cost. FWIW, for the small amount of extra sail area you keep with the battens, I would recommend going the simpler route and just use the leech hollow method. This is what the Hobie 18 jib looks like, for example. Hope this helps!
