I bought a capri. First boat. Got a great deal and this might be why. The luff groove is spread about 15" below the top of the mast. Is it possible to pinch this back in some way? I will slide a bar in the groove to insure it doesn't close too much. But just wondering if there is any ideas on what to use. heating ect. This is my fist post and glad to see you guys are here. Thanks.
