At that point you have to grind off the fiberglass and move to Arizona
for a month or two.

This must really sound weird to the thousands of plywood sailboats
owners. There are plenty of 30 to 40 years old boats still sailing. Well
painted marine plywood is very durable.

I was talking about marine plywood skinned in fiberglass.
The fiberglass will eventually get cut or broken. And then
moisture will migrate in the plywood core. This happens a lot
faster on driftboats than sailboats. But the process is inevitable,
at least for plywood that stays in contact with the water a lot.
