      I need to buy some plywood to replace the big hole in the sole I made
      glassing in the new fuel tank. The question is: what is this stuff?

      Is it CCA marine grade doug fir plywood or just CCA (non-marine)
      plywood, or something else.

      What are people using these days? I can find CCA plywood (non-marine)
      for about $32/sheet and I can find marine grade, not CCA plywood for
      about $97 a sheet. In any case, I need about a 48 x 48 piece of the
      right stuff. (the CCA 3/4 marine ply sells at the coast for about
      $65/sheet, but I can’t find it here). I wonder if you can just put a
      shipping label on a 4′ square piece and send it via UPS….

      Knowledge and ideas?

      Thanks,

      Pete

      I am in Fort Collins, Colorado. My boat is here for a several year
      restoration. (It is a Blue Water Sailing project boat and you can
      follow the project in their magazine starting this summer with an
      article on trucking the boat out here).

      Pete,
      I don’t know CCA for non-CCA, but clearly the sub-floor plywood I removed
      during my cabin sole hatch project this spring was not marine grade. That
      is, if my knowledge of marine grade is correct – zero voids.
      In any case I had to replace one section of the hatch subfloor and I used
      MDO plywood. I’ll let you know in 10 year or less if that was a good idea.

      The subfloor and beams are not marine grade. The beams are simple 2×3
      douglas fir which is resistant to rot (clearly not if it’s submerged). The
      subfloor is standard 3/4″ plywood, and for the same reason.

      Unless you plan to keep your bilge wet all the time up to the top of the
      keel, I’d say, the stuff lasted 32+ years. Why mess with success.

      Another way to tell is that standard and marine grades of plywood are
      different thicknesses – marine is about 1/64th inch thinner. Maybe a 32nd.
      I forget which. If I were to recommend plywood replacement, I’d suggest
      exterior grade. It’s only marginally more expensive than interior grade.

      At any rate, that’s what mine is, and it’s #8. I seriously doubt they
      changed materials in later models, but who knows?

      I hope that helps and saves you a bit of money.

      I talked with them yesterday in fact. I can get a variety of marine
      plywoods here in ft collins, but I was thinking that I needed to get a
      CCA marine plywood. Still unclear about that.

      Thanks Bob. Mine does look like a doug fir plywood but I thought it was
      treated. Plain plywood 30 years ago was nicer than it is today. Many
      fewer voids, etc. Yes I can get a sheet of 3/4″ exterior treated ply
      for about $30. Makes sense since as you say it will not be directly or
      constantly exposed to water.

      Pete,
      The guys a the yacht club replaced part of our small boat ramp with marine plywood and it truly is the right stuff. I will include a member in on this email to see if he can provide you with the source.
      Niels, where did you find the marine ply for the ramp project?

      I assume you’ve probably seen this.
      http://www.richardcarter.net/boat/sole/

      Unless you want to replace a large part of your cabin sole, you might find
      it easier to use the plywood venere. Laying in solid strips isn’t all that
      difficult however. Especially if you have an odd shape to fit. Its about
      the same price as plywood.

      I am planning to overlay the entire sole with bamboo and teak (bamboo
      for the wide strips and teak for the narrow/ 1/4
      thick. This will be the last project of the refit. After I am done
      making all the rest of the messes.
