Went to check out a 85 Mac 22, when I was moving around inside the cabin, there's this loud crackling sound coming from the hull, is this normal?

Good question, wish I had more experience to help, there’s so many variables. First thing I think of, what is it sitting on, is it bunk noise (trailer) could be in/on under the new plywood. I can’t see it being the hull itself just something shifting on it. Looks like someone has put quite a bit of work into her.

It's on trailer, I asked seller about it today,he said it's the plastic inside the cabin. I don't know what it's called, it's the plastic mold/liner that covers the inside wall and berth. Had a 74 Mac 22 years ago and that one didn't have the liner, just paint over fiberglass.

Is there was to get rid of that noise or at least minimize it
