A complete tank test of a model of a flying-boat hull-N.A.C.A. Model No.11
A 1933 NACA technical report, NACA Technical Note No. 464, issued by the National Advisory Committee for Aeronautics in the United States for aeronautical engineers and naval designers studying seaplane hulls. Its pictures are plain black-and-white line charts of tank test resistance and trimming moment curves against speed, plus a drafted hull lines plan, useful to a designer for the restrained grid-and-curve vocabulary of technical engineering graphics.
