Seaplanes floats and hulls. Part I
A 1927 technical report on seaplane floats and hulls, issued by the NASA Technical Reports Server collection and drawn from aeronautical research of its era, written for aircraft engineers and designers. Its three pictures are engineering charts: a grid of curves plotting load against speed for floats, a family of labelled weight-and-speed lines with a set of diagonal guide lines, and a tall plot of float dimensions against a vertical scale, offering a designer a sense of how technical data was once drawn.
