: Thanks Dave.
: Actually I meant 3/8 only at bow and stern sections (if not so
: wide) and 1/2 for the other sections.
: The seller writes that ply is for internal use but also claims the
: clue is WBP (wheather and boilled proof).
: WBP is not for "water proof" but i think even marine ply
: is not.
: Half price is charming... I just doubt about the birch.

How many ply? It's veneer core, right? The face grade is probably not important, but sometimes cheaper plywood has a lot of voids in the interior ply, and that could be a problem. In the worst cases I've seen voids under paper-thin face veneer, which would be a bummer on a kayak, especially if you have really thin cross-sections, because it will weaken the bulkhead. If it's baltic birch ply you'll be fine even if it's not aircraft certified, because they don't allow knots or voids.
