Good morning John,
I'm interested to see your progress and final product. I also have a 1976 23' inboard and the rear deck is basically solid with a couple small soft areas and a slight sag in the middle. My deck appears different underneath as it is only about 1/2" thick with 6 or so transverse sisters (1/2" - 3/4" x 1 1/2" high beams) running the entire width except for where the hatch meets the deck. Was your rear hatch seam caulked to eliminate water intrusion? Do you have any pictures of your hatch that mounts in front of the console and partially slides underneath? Mine appears to have been modified (molested) over the years. I'll send you a PM also. Thanks.

Barry
