Determination of resistance and trimming moment of planing water craft
A 1931 NASA technical report, drawn from the NTRS collection, on calculating resistance and trimming moment for planing watercraft, written as an engineering study for naval and marine researchers. Its pictures are plain engineering graphs: curves of weight, moment and force against speed in metres per second, drawn in black line with fanned straight construction lines and small circled data points, offering a designer a clear model of technical charting.
