Sounds like the plywood under the cockpit fiberglass is rotted......been there done that....do a search with the words cockpit floor as a search and you'll find some info
Any thing you need to know about the 32 just ask......I have a 10 year always doing a project to make it better
This is from a post I answered back in Dec.
"Well you came to the right place cause when I purchased my 32 I had the exact same problem and at first I was going to cut the fiberglass from above then after I studied the situation I realized what mistake that would have been

so plan B for me was to remove as much stuff as possible from my engine room which is below my center
cockpit and then after removing the steering pedestal and all the old laminated plywood, I then placed about 6 cement block on top of the
cockpit floor(you'll see later why) then I got a sheet of 3/4 marine plywood all cut to fit and propped it up with a bunch of 2x3 crutch's then after I was satisfied I removed the crutches and whipped up a batch of West System thick like peanut butter and placed the plywood up with the crutches and additional shims to get it good and tight, the cement blocks helped the deck from bowing.....the next day I removed the shims and installed another sheet of plywood with epoxy and screws giving me a 1-1/2 thick deck that has held up nice for the last 9 years
BTW: make sure you cover as much of your body and other boat parts as possible cause West epoxy sticks and won't come off! I used a few boat seat/cushions to lay on and still have them with epoxy all over them and there's still a few globs on my heater hoses "
