I recently purchased an old Sears inflatable boat with a soft rubber type bottom, no seats etc. I would like to put a hard floor in it so that I could fish out of it. It does have a transom that mounts off the back of the tube, and I have a small trolling motor and battery. I have some marine plywood and 2 inch styrofoam insulation board. Do I just cut it to shape and slip it in after blowing it up? Do I cut it to size from the bottom of the boat and just make it a 1/2 inch smaller? Do I need to cover the plywood with something?
