Tank Tests of Models of Floats for Single-float Seaplanes First Series.
This 1936 NASA technical report presents tank test data on scale models of floats for single-float seaplanes, prepared for aeronautical engineers and naval architects studying hull performance. The pictures are dense engineering charts of draft, trim, resistance and trimming moment plotted against load and speed, drawn as grids of labelled curves in black and grey lines on cream paper, with the parameter values written directly on each curve, so a designer would find only their graph structure and labelling conventions useful rather than any visual style.
