While reading the documents produced by Thompson about their boats they refer to the planking as having a phenolic overlay for durability. My understanding is they are referring to a paper that is on the outer layer of the plywood that was used. Am I understanding that correctly? I understand it as a paper that is coated, or soaked in a phenolic resin, and that resin would be some type of epoxy.

Yes, this is the paper overlay on the plywood planking. Today it's called MDO for medium density overlay.
It made a very smooth surface for painting and minimized checking of teh wood, thus the finish.
Thompson Bros. Boat at Peshtigo started using this about 1963. T & T Boats and Cruisers, Inc. both used it as well. T & T used "Crezone" brand. Not sure what brand was used by the others.
Don't sand thru it when stipping the old finishes off the hull. You'll regret it.
