I know they changed stuff on the Trackers but on my '76 23 it was just a sheet of 3/4 ply with a single layer of 22oz roving slapped on top - no resin or glass on the back side and no putty to bed it. When I pulled it the wood was heavy and rotten. I was able to just rip the glass out - very poorly bonded to the stringers - I only had to use the grinder for about 5 minutes to clean it up afterwards. Way easier to get out than I expected (good and bad). I replaced it with 3/4 Coosa and even with glass on both sides the new one weighed about 20 lbs less.

Smelly 3/4 ply w some resin on top. Missing in many spots.

Tried to save it but that made no sense.

Got some bilge coat paint.
Might as well.

My Slacker was made in November which is perfect Sarasota weather for glassing with cool temps, low humidity, and the work is surprisingly good, but they tabbed the coffin to the stringers with woven as well. No glass on the ply other than that, just resin... no glass or resin under deck either.

My boat sits right down when I fill my above deck live well under my arse.
She likes weight which is contrary to many thoughts from the sixties and light, right motahs.

Thanks for all the thoughts and personal experience.
Cheers,
