bow eye ring replacement question

[Tom Bare]

The bow eye ring is shot. Lucky the boat did not come off thge trailer. Looks like 3/4" of thread out of hull on the bottom.

There's no access to the ring from the inside. Was thinking of Dremel for cutting a rectangle out to get to it.

Is there a backing plate, is it glassed in, etc. Will I need to glass the piece back in or will 5200 work [for future access].

Anyone with experience on the best fix who's willing to share thoughts would be apreciated.

Thanks!

Tom.
