Driving back from the coast, a lawnmower shot what must have been a large carriage bolt just over my family's heads and into the bottom of my Chesapeake 17. The head of the bolt penetrated the hull just under the front hatch and left about 2" of threadmarks below the hole.
I'm looking for advice on the fix. My current plan is to apply epoxy in the hole to seal the wood and mix with wood flour to fill any remaining gap. Then I was going to start the sanding, glassing and varnishing routine. Any other suggestions?
