All stern drive boats have fiberglass skin over wood transoms. Most wood is plywood (called core) encapsulated by the fiberglass skin. However, many production boat builders do not do a very good job of sealing the cut-out for the drive and over the years water can (and will) migrate into the plywood core.
As for the stringers.....same thing. Most are glass over wood core, but not all. Your 1994 Chris most likely has wood core. It gets a little more complicated than this, but you get the gist of it.
At 21', I am not sure if your decks are cored or solid fiberglass. But another reason for hiring a qualified surveyor is that voids or delmaniation can also be discovered in the fiberglass bottom or deck.
Just because a boat is fiberglass does not mean there cannot be problems with the lay-up of the glass.
I am surprised that your lender and/or insurance company is not requiring a survey.
