So I have most of the wood out. Not a fun job. It apears that the rear plywood sheet went down all the way to the hull and the forward sheet sat on the glass that encased the core. I have gone down to the hull the full thickness of transom. The core wood was dry and had the grain going vertical. Is that the later building style?
What is the best way to glue the 2 layers together? I am going to be doing that at the same time I glass them to the skin. I plan to bolt a 2x12 to the back through the holes for the tie down hooks the clamp through the I/ o hole when I install the new wood.
