your belt and braces approach. I really appreciate your tip about the moving belt: ultimately that may be a deciding factor since I sail with a Australian sheppard that is highly attracted to things that move and make noise! I'm getting a bad mental picture.. BTW, welcome to the board! I find that there is an amazingly friendly and experienced group here that always seem willing to help out. I've met a few in person and have always been impressed. Thanks again, David
