When I was doing the planking on a model sailboat, I found hot hide glue invaluable. Pinning those tiny planks so they form to the hull and waiting for PVA glue to dry was taking forever. When I switched to hot hide glue I could get 3-4 times as many planks laid in the same time it took with PVA. Cleanup was also a joy. No need to worry about glue marks ruining the finish.

One comment I found interesting was when someone said, "I hope you're not going to put that boat in water!" There was some story about a Roman emperor who wanted to murder his wife. He made a boat using hide glue to secure the planking and gave the boat to his wife as a gift. When she sailed it out onto open water.....
