Has anyone used stall mat (firm rubber 1/2" to 3/4" thick) to help spread the load on trailer support pads? I'm using two 6"X 6" fully articulated pads spaced 6" apart on each vertical support. If I could turn the boat upside down I would build pads to the contour of the bottom with fiberglass. This worked great on a plastic kayak.
Checking out boats on trailers with a thin piece of plastic (credit card thickness) placed between the hull and support the only boats with much support were flat bottom. Boats with a compound curve, like a sailboat, had a very small area actually touching the fiberglass until the laminate deformed. Bunks were the worst and I've always thought they were the best. The only place the plastic wouldn't slip through, unless the hull was deformed, was near a support on every trailer except flat bottom boats.
