Do you feel the structural design of the beam-hull bolting system was meant to support the DOWNWARD force of hanging your hulls? The entire weight of a bouncing hull being trailered would be held up by the treaded mount in a fiberglass deck lid and hull socket. It might not matter with a 165 pound A-Cat but a 400 pound F18 could be more than the joint was designed for. I could see a disasterous ripping out and dropping off a hull as you bounced over some railroad track crossing. Yikes!
