============================

That's partially correct but you need to look underneath the layup to
find the real price cutting. The use of non-marine plywood as a
coring material, and inadequate or non-existent core encapsulation are
some of the major issues which lead to lack of long term durability,
regardless of manufacturer.

Once the wood core in a boat is damaged (bulkheads, transom,
stringers, floors, decks), the boat is pretty well shot since repairs
are not usually cost effective in a low end boat.

If the plywood is properly encapsulated, it not a problem. However *I DO*
see your point if that encapulation fails....

If it isn't the right kind of plywood, it could be a problem, even if it
is encapsulated.

Absolutely right, marine plywood is built with higher grade wood,
minimal voids in the plies, and with better glue. Surprisingly
enough, that costs more.

Hmmm.... I never thought of that. Seems right to me. Curious, within
Non-Marine Plywood are there different grades? Just wondering...

Many different grades, depending on appearance and intended purpose.
