Re: what can I expect to se
Not sure about Trackers specifically, but generally aluminum hulls will have foam and aluminum stringers that tie in the deck to the hull. I'm guessing you have spray-in foam which is a bit more difficult to deal with, especially if it's waterlogged.
Some(like my '79 Starcraft) had solid sheets of foam from the factory but the industry switched to spray for unkown reasons(probably cheaper).
Good news is...tin cans are MUCH easier to work on than 'glass and you will be able to replace the foam with closed-cell that doesn't absorb water.
Check the pictures in my resto link below if you want to see some examples of what you may see. Any late 80s Sea Nymph/Starcraft/Sylvan restoration thread should be close to what you can expect.
