RE: Boothbay Oyster boat
Kevin I guess this is the way I will go then. The idea of the ballooons was just a loony idea that hit me as I was about to close the post. Having the frames sealed off in the transom area is great. The shot should find its way to the lowest point which would be the keel area, then adding resin which will always find its own leveling height. Thinking of doing it this way I can seal off the hole like you did with silicone. I can then just add a wall which will fit under the transom hatch to the top of the deck and look normal.
