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?
Is this crackling sound 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

Probably not.
Possible.
You could do that.

When it's in the water it might not be so bad, water supports the hull better. I'm sure there is a way to track it down and quiet it, but it might take some work to take down the liner and secure it better.
It's called the liner - so you got it.
My guess is that whatever method was used to attach it and/or the bulkheads to the hull has come loose. That would take a significant collision. Fiberglass hulls are flexible until they are stiffened with the deck and internal structure. You should give the keel (Fixed or movable) a careful look including the fiberglass that support those structures. And the bow for evidence of a repair. The port side topsides around the cockpit is another area to check because that's where port/starboard disagreements get resolved.
A loose liner can be repaired but it is labor intensive. If you have professionals do it the expense will be significant. DIY is manageable if you have the skills and you have access.
