The short story is that if the detabbing is at the bulkhead and the

just wedging it open, flowing in epoxy and then screwing it down will

That sounds reasonable if as you say the bond area has not been
contaminated. If the gap is large, consider "Plexus" a thick gap
filling adhesive widely used in new boat construction.

If the gap is thin, temporarily wedging the tabbing open and pouring
in liberal amounts of epoxy, and temporarily screwing the tabbing back
to the bulkheads will do it.

On our 30' last boat, the survey noted a few instances of de-bonded
tabbing. In my inexperience, I took an angle grinder and got in
lockers, closets, and under bunks and ground out almost all the
tabbing and re-tabbed with new material. Lots of work but it didnt'
take that long- about 1 month working most evenings after work.

If you do have to re-tab some areas, use epoxy; the fumes alone from
polyester in close quarters will be unpleasant to say the least.

The outside pics don't seem that bad, and retabbing bulkheads etc.
don't sound that bad, except for the areas of limited access like the
refrigerator. In those areas where you can get at one side, lots of
tabbing on the one side is nearly as good as both sides and is
probably quite acceptable.

If you think the boat is still worthwhile don't let the insurance
company scrap her on you. Negotiate, bargain, etc!

Good luck to you,
