My father had a converted lifeboat (North Deal, iirc) from about 1890. 45' long, built as a rowing boat, it had two layer diagonal planking.Diagonal planking persisted well into the 20th cent. One lair at about 90degrees to the other. Made a very strong construction. Expensive yachts, ww2 patrol boats and RNLI lifeboats spring to mind.
