I recently built and launched a little rail skiff/ duck boat out of cypress. My intention was not to build a yacht like thing, but a simple, traditional, purely functional and inexpensive boat to pole through the marsh and swamp. Therefore, I did not want to go through the trouble of screwing and bunging and sanding a bunch of holes. I had the notion that some years from now the boat would have a vintage look, a future antique if you will. So, I used SiBr (anullar) ring nails for all the planking (3/4"). The bottom is nailed on with 6d (2") nails and seems to be fine, but the chine was nailed with 4d (1 1/4) is peeling away from the side plank after only a week in the water. I didn't want to get into 5200 or epoxy or any modern, high-tech stuff here. What did they used to do back in the old days? Maybe I should have clinched the nails from the outside plank through the chine. This just didn't seem right, either, to have so many holes outside the hull right at the waterline. Any constructive comments are welcome. Rivets?
