On our c250 tone of the hinges on the port laz needs reattaching to the boat. I would simply put a bolt through and attach with a lock nut but the other side is a completely sealed compartment.

I could use the next sized screw and hope that holds with epoxy.
I could add the next sized screw and epoxy the hinge to the boat (lame move) in case the hinge fails some day....

Any ideas.....has this happened on your boat?

It's been quite awhile since I did it and it's held up good but I could reach the back of the aft hinge by crawling head first part way through the aft bulkhead. It was tight. I used a small saw and cut a round hole in the liner to reach the back of the forward hinge and then installed a screw in deck plate in the liner. Installed larger bolts, lock nuts and large washers for the hinges. If I recall correctly I also cut, drilled and installed wood backing for the hinges.

Good luck.

Do you have any clues on how Catalina did it? Is this an exterior mounting exposed to weather so bedding is required? I can't see what you're describing, but guessing Catalina attached the hinge after the fiberglass was assembled... Molly bolt? Toggle bolt? Some other sort of sleeve? (If any of those, make sure they're stainless.) If it's with self-tapping screws, that's (obviously) not a good way to mount something in fiberglass if it moves and stresses the mounting.

Some installations on the older C-25s were done with bronze plates glassed inside before assembly, and then drilled and tapped afterward so only a bolt was used to attach something (like a gudgeon). Of course, if the threads eventually stripped in the bronze, then something else had to be done, sometimes requiring cutting and installing an inspection port.

I have heard of epoxying a bolt into fiberglass after coating the bolt with melted wax, so that after the epoxy sets up the bolt can be removed, leaving perfectly formed threads in the epoxy. It's probably more secure than threads in ordinary fiberglass, but I've never done it and wouldn't trust it for a hinge.

Is there enough room or depth to drill out the hole to accept a knurled threaded insert? If you drill out the hole to ensure a snug fit, you can epoxy or krazy glue the inserts in place. The knurled texture usually helps to bite into the fiberglass backing.

Something like this here

I had the same problem a few years ago. I easily resolved this with pop rivets.
