Can you hand sketch a section of the hull deck joint? I see where the deck overlaps the transom in your picture and is screwed or through bolted as I can see the heads of the screws under your epoxy. But I'm not sure what happens down the sides of the boat. Most manufacturers either have mating flanges turned in or turned out. Ours don't seem to have that. I don't know if the 1/2"x3" horizontal rib is part of the hull or deck. I would assume the hull. If so, does the deck turn down and overlap the hull (like the transom) and rest on the 1/2"x3" rib? The hull then should turn back up after the rib about an 1" to make the joint. Is that rib solid glass or just a turn in the mold of the hull?
