Does anyone know where I can buy marine grade plywood in the fredericksburg area?

https://www.marine-plywood.us/douglas%20 fir.htm This site says using pressure treated bc douglas fir is good to use. That stuff is way more common than the marine grade

Dan, you do not want marine plywood. Marine plywood is a structural grade and is NOT waterproof. marine plywood is a structural grade and is not waterproof. It will quickly delaminate when wet. What you want is special pontoon deck plywood. It is available online from pontoon stuff or pontoon specialists and several other sites. It runs about $65 to $70 a sheet. At least it did about 6 7 years ago when I rebuilt a pontoon deck.

If you do go with marine plywood be sure it is pressure treated for exterior use.
