Kirt, regarding "fear of rollers on hulls", I mean the rollers that roll along the inside of hulls, not under hulls. As I push my boat further forward on trailer, inside rollers begin to rub hard on hulls - not woried about damage as much as nasty black streaks on inside of hulls caused by rollers if I push boat to far forward on trailer.
Thanks for your ideas. Your right, that mast is heavy!
