Hi Steve, I have always put a long wood 1x2 with the bottom shaped to fit the hull & epoxy or AC glue it in. It is to take #6 or #8 x 3 1/2 " wood screws to go thru the base & the pedestal & into thr 1x2. I even did this or something like it when I built wood plank on fraame models. They might be 3" screws.
