Re: Plywood Again??? Forget Marine Ply!!!
- The APA (American Plywood Association) stopped certifying
domestic "marine" plywood in the early 90s due to inability to
certify that inner plies had no acceptable voids .....
didn't see anything about re-instituting the grade
So it's imported (non-US) or exterior grade (glue used on inner
plies) at Gougeon they always recommended a "boil test". Cut a small
corner at pop it in a pan of boiling water for an hour or so. If it
doesn't delaminate then you should be in good shape.
I always got mine at Detroit Lumber excellent prices for 3/8" AC

- That's exactly what I did. I don't know how thick their skins are; but If I
were in a position to order a boat build that way I'd insist on a filling of
the slots at leats with more foam.
I really don't claim or want to argue my point beyond the fact that I looked
at it in a very amateurish way; but decided I didn't trust this method; or
voids and gaps between skin sheets in a composite.
Now no matter how wrong I might be; I'm never going to be particular happy
in a boat that has this issue; so I avoid it.
