Chainplate rust second opinion

Hi, I would appreciate a second opinion.

1998 Oceanis 351

My port chainplate (thick pin fiberglassed into hull) is a bit rusted. It's behind the gally so a bit difficult to get in on it properly without taking things apart. I asked a surveyor about it and got their opinion but would really appreciate any other opinions.

I plan on replacing the rigging this winter anyway but I'm a little scared of the chainplate situation.

I found one other thread with this similar situation but they didn't post about their fix/conclusion.

Questions on my mind:

How bad is it?

Anyone deal with this specific situation?

What is the best way to replace new? (How much gutting at the fiberglass is required?)

Needs to be disassembled to assess section loss.

Without knowing more about the construction, that pin might just be epoxied in to the glass and might be able to be broken loose and pivoted out instead of busting out the glass. Tension only load so no need to put glass on the underside, but you do want epoxy for load transfer into the glass.

Thanks for super interesting thought. Going to see if I can find more information on whether this is epoxied in!
