1983 Charger Firefox

I have a pretty good condition charger Firefox 185T. It’s all solid except for the front deck on the sides. Solid in the middle. Looked at inspection hold and it looks thin on the sides. Has dry foam under the deck. Drill holes to test wood and dry wood came out but seemed very thin. Is this normal to have flew in this type of deck? Doesn’t look rotted from 2 holes drilled.

Bud, Bayliners were so thin you shine a flashlight from the inside and the whole side of the boat glows. If
chargers were made thin, it has not let you down yet, I wouldn't worry about it.

Okay. When is it something i should worry about? Ha
