Having that extra wieght dangling off of the back of the boat while bouncing down the highway has to take its toll on the glass and I doubt very seriously that it outways the benefit of saving three minutes on the beach while setting up. But I guess if it does you can alway call Jake. I hear he has gone into the fiberglass business full time. <img src="http://www.catsailor.com/forums/images/graemlins/grin.gif" alt="" />
