Looks good, the cuddy deck more than likely the ply they used is compromised. Rot from screw penetrations and top cleat and even the sliding deck brackets. I’m currently doing same repair on my project using 3/4” ply and glass. The pins that slide in hatch brackets may need to be longer so sliding hatch doesn’t come out of brackets? Wonder if someone modified it before.
The deck glass has wood bonded to it underneath for strength. Both my FF boats they only put resin on the exposed wood on the inside. Look from inside cuddy , is it carpeted or covered?
Ok , Yea they stripped the old wood out. Originally Aquasport installed some wood runners that ran along the sliding hatch opening on both sides underneath from the bulkhead to bow front. Between them was ply forward of sliding hatch opening. The bolts go through deck top runners and and lower runners. My 222 FF runners the hatch slides in are stainless steel. Not sure they were original all I have seen are wood as with my 79 19.6.
