What type of Plywood?
 

I need to replace the cabin wall in my 71 Seafari. The panel that is there now is some type of plywood laminated on one side. Do I need to buy marine plywood or can I use a regular type wood with finished sides? I plan on painting it white with an automotive grade paint to seal it. Also looking for ideas for a cabin door and a place to buy what I need that is local to Brockton, MA. Thanks

For some interior panels on my boat I used regular old Luan from the HD. The same stuff they use to level floors in 1/4" thickness. I laminate it to the thickness I need. The advantage is it is skinned with a low grade Mohaghany and actually looks pretty good when covered with Cetol. Bonus is it costs about $12 a sheet and is void free, just a thought. A little labor intensive but I think you end up with a quality piece of wood that is very stable. I used Epoxy to laminate but you wouldn't have too. Check it out.

I dont know about other ply woods but marine grade plwood is A/B firr it is smooth on both sides you can get A/C firr (half the price) and it is still exterior grade same as marine but only smooth on one side. I hope that helps. Jose

One place to try in Mass. is Boulter Plywood (24 Broadway, Somerville, MA). I'm not sure how competitive their pricing is, but I have bought both solid teak and marine ply with teak veneer laminated on both sides from them, and was very happy with the quality of the stock. Good luck.

If you are going to use plywood impregnated with resin and use fiberglass for strength and to avoid delamination with a damp environment, use Fir plywood. Fiberglass will stick to Fir. I recommend using a good grade of oil based primer to raise the grain, sand, apply a second coat, then your color coat, all of good oil based paint. If you're considering a two-part epoxy, go with their recommended primer from the get-go. Have fun.
