+1 on Josh’s comment: That chain plate and those bolts looks pretty suspicious on their own.
I pulled my ~ 30 year old port shroud chain plates in August, 2015 and on the surface looked a bit better [less apparent rust] than yours, but the sides of the plates that were against the bulkhead were very rusted and pitted [stainless and lack of oxygen never a good thing] and several of the bolts holes had cracks in the steel radiating out to the edge of the stainless plate. These cracks were not visible to the eye on the exposed surface. All of the bolts were quite rusted, two sheared off as I removed them. Was not expecting to need to replace them but was not worth risking the rig over $500 to have new chain plates fabricated and a handful of new SS bolts.

Tabbing from the back/bow side might be a trick. I'd cut the exposed tab, remove rot, grind to clean fiberglass. Generously goop thickened epoxy onto the remaining tabs and clamp your pre-fabbed G10 into place. Then filet and tab on the exposed side. Be sure to inspect thoroughly for cracking in the SS fasteners and chain plates... Or simply replace. Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD
