Investigations and Tests in the Towing Basin at Guidonia
A 1939 NACA technical memorandum on experiments in a towing basin at Guidonia, published by NASA's Technical Reports Server from NACA archives. The first plate holds wiring and pulley diagrams, graphs and sketched hull profiles, and the second shows photographs of a ship's stern, a finned or coiled cylindrical object, a rigging line, and a crewman on a deck ladder. A designer could take the crisp black-and-white diagram layouts, plotted curves and grayscale ship photographs as a restrained technical plate style.
