the bowrail mounts are rotted.
so I have to continue to cut this 1.5" ditch all the way up to the bow and remove all the rotted plywood.
Can't reach to put backing plates or even washers where the bow rail has rotted out.
my idea was to First cut a ditch and remove all the rotted wood. Epoxy oak in it's place and glass over. Re-drill and attach the bow rail.
Was thinking if I put an access hole here
I could reach inside afterwards with needle nose etc. and install washers, lock washers and nuts. Then glass over those holes and be done. Continue that process for each mount.
There is dead space where the thru bolts are now and can't be reached.

What are some other ideas? Aluminum plates epoxied in place then drilled and tapped afterwards?
