Rosscoe .... The bunks of the trailer happen to sit right on the stepped portion of the hull that the floor sits on. The upper portion has relaxed, and I'm ok with that for now as I am pulling things out. Before ANYTHING goes back in, I have measured the width of the deck at 4 points. I used those measurements to cut a piece of wooden closet rod for each point. I will place a screw through the hull where the rub rail would attach and secure it to the ends of the closet rod (no doubt it will require someone on each side of the hull pushing together. Then, I'll pull a chalk line from the center of the bow to the center of the transom and measure each "half" of the closet rods. If I've got the same measurement on each side of the chalk line, I will assume I'm not twisted. If one side is longer than the other, I'll have to push that section of the hull in. I may have to lay another piece of wood (a very straight piece) across the center like a spine and ribs. That's the plan, anyway. It will look like an obstacle course as I work on it, but I'll get my floor in and some lateral support pieces cut. Then I'll put the deck back on before I put the lateral supports in (like the bulkhead). I can lay on my belly and glass those in. At least this way they're glassed in with the deck in place & if I remove the deck it should hold it's shape a little better than now.
