This physical modelling approach seems similar to what is in "Canoe and Boat Building: A Manual For Amateurs" which was written in 1889, and which I got off the web in e-book form. One refinement is that they make their original block of wood of several layers of woods of contrasting colors, held together by screws so they can be taken apart and traced. If I understand the illustration correctly, their layers are horizontal (correspond to sections parallel to the water) They also go from plans to a physical model by building the model of layers of cross sections and then fairing.
I only just started reading this book and it's riddled with typos, which are amusing in the text but infuriating in the numbers. How deep is J inches of draft? 7, maybe? S inches is probably five, but what's x? The original scans are available online so maybe I'll be able to puzzle it out. I will probably post more on it when I'm done.
