Transom work

I removed the chainplates, swim ladder, from the back of the boat. The transom is thicker than I thought (about 2 inches). The chainplate holes were mostly dry. The fasteners for everything were rusting.

I overdrilled every hole and sealed with very thick epoxy. I will redrill and remount the chainplates/backstay this evening. The ladder needs to be cleaned up or replaced.
I'm mostly concerned with waterproofing the core with the epoxy fill method.

I may also add backing plates to the chainplates at that time.
