: Looks like these are my only local options in marine plywood.

: Douglas fir A/D quality 1/2" is $55 a sheet

: Another supplier has Meranti or Okume but only 3/8" thick or 3/4".
: 3/8" Meranti is $97.50 and okume is $112 a sheet.

: I have someone asking me to build them a boat. I am trying to decide on which
: plywood to use. I am leaning toward the 3/8" Meranti because I feel
: like it will be better quality ply. Playing with some 3/8" plywood
: mockups I don't really think that is going to be an issue. If were were
: beating around the surf then maybe.

: The Douglas fir is much cheaper but it is A/D quality and I am afraid the
: core will have voids in it. I don't know this of course, just a feeling. I
: realize I could turn the A face toward the cockpit and put the ratty side
: away but I don't like having a ratty side period.

: Given these choices what would use? Shipping in 1 or 2 sheets of plywood will
: not save me anything. Shipping costs are just to high. So I need to buy
: local (for now).

Hey Jeff-

I'm not sure what the specs are for marine plywood. I know that BS 1088 requires no voids to be certified, but you can check the specs for the A/D Doug Fir at the site below if your dealer doesn't know. The Okoume and Meranti should be BS 1088. Why can't you laminate two layers of 3/8"? A Yost doesn't require more than a 4'x8' sheet does it? You could cut one set of bulkheads, laminate on another thickness of material with a rough shape cut, and pattern rout it to make sure you've got identical pieces.
