Screws pulled out of rear hatch hinge... suggestions?

How about using blind nuts?

There are many rot proof options out there, they are just too expensive. Even multi million $ yachts use plywood where they shouldn't. Here are some pics of a yacht we just repaired that used balsa core ply in a structural area that gets wet. We cut out the rotten ply and added a piece of Coosa board, glassed it in, faired it out and painted.

How about using blind nuts?

I'm loving that idea. As long as the "anchor" part of the nut will secure to the fiberglass part of the hatch.

I also see what @Murf'n'surf is saying about keeping moisture out. What about filling with a silicone sealant before mounting with these blind nuts?
 
Whatever route you take, make sure it's sealed tight with rtv or silicone or 4200.

The more I look at the blind nuts I don't like them for this application. I think they might open up the would more than expected and possibly crush the glassed area in order to bite.
 
I have to remember to take some pictures of mine to post for some opinions. . . . . . But the "precision" drilled holes for the front anchor hatch don't seem to line up properly with the hinges. As such the counter sunk screws are sitting funny in the hinge. I don't see an immediate problem with it short term. But long term I think an issue could develop. I will post some pictures next weekend when I get back to her.
