I feel your frustration. Can you tell us more about the type chainplate, the boat, and post a photo of the area, ect? Lot of smart people here but we could use a little more info.
Thanks. Does anyone use food coloring or some sort of tracer to aee where water us getting in? I swear I locked down that chainplate with butyl.If the deck core is soaked, then that can continue to weep water through any opening. Water from leaking deck hardware can definitely travel to another area and come out there.
I did pull the chain plates….Fiberglass does not rust, Stainless Steel chain plates do and I suggest that may be the staining you see. You need to remove those plates for a proper inspection. All the fittings shown below are at end of life.
Not great resolution but the first photo certainly appears to have some significant pits and fine fractures at the bottom hole. I suggest you have a rigger look at them.I did pull the chain plates….

The photos below are an x-ray of a single pit on a prop shaft and what that shaft looked like when inside when it broke, the principle is the same. A single pit, pinsize on the outside is very likely hundred of times larger on the inside.
Decay of FRP on the deck or even delamination or blisters is highly unlikely. You just need to seal everything well. I'm surprised the butyl failed, I've never seen it fail before ... you did seal it from the outside right ?Thanks!
i guess my question was. Can a non-cored deck still rot, get soft, delaminate and have cleats etc pull our under load?
clearly I need to rebed everything… and probably get new chain plates fabricated. That may cost more than what i paid for theboat😃
The bottom hole is of little concern. This area that is buried in the deck, however, is of great concern.Not great resolution but the first photo certainly appears to have some significant pits and fine fractures at the bottom hole. I suggest you have a rigger look at them.
Thanks that is really considerate! Next time i pull them i’ll do that.Send me a sketch with dimensions and I'll send you a Cad DXF file that you can send to SendCutSend.com and they will laser cut you new plates fairly inexpensively. Choose 316 stainless.
