The floor is done!!!
I used 1/2" exterior grade plywood commonly available at home depot or lowes. I used cardboard to create a template. I ended up doing 3 sections leaving a 1/4 inch or so gap around the edges. All wood had at least 3 coats of resin before I put it in the boat. This includes the edges.
I laid matt cloth along the top of the stringers and wet it down and then thicked resin along the edges allowing each section to harden before I moved to the next.
