The butt of those soft padeyes makes the glass patch over it sit about 1/8th inch higher than the surrounding wood. Just a touch on that bulge with an electric sander and coarse sandpaper will rip through the glass and a bit of the padeye, but completely miss the surrounding area. Poke out the old padeye pieces, use a small piece of medium grit sand paper to clean up any grunge on the inside, insert a new padeye, and slap a patch of epoxy-wetted fiberglass fabric over the site.

For those who either don't like to use epoxy,or who are fans of duct tape: They can seal the inside with a square of the 'universal silver solution', and be done in a moment.
