Good point on the warp, that's why I recommended the fir because it will not not warp like pine, and OSB is junk. Just so we are clear, I'm saying you don't need treated plywood unless the boat sits open and uncovered outside. If you paint the CDX fir (that's an exterior grade plywood to begin with), that's water proofing it plenty... and your boat will be lighter. Pick-up a sheet of either treated and then a sheet of CDX at the lumber yard, you will notice a big difference in weight. | |
