In considering the design of marine aircraft, viz., flying boats and
seaplanes, an entirely separate and additional subject is brought in for
investigation, and upon which there would appear to be much reserve as to
definite formulations and data, etc. This subject, which I prefer to entitle
“Hydrodynamics,” can become, besides interesting and absorbing, certainly
most deep in its complexity, and it is realised only too well by those
actually engaged in such investigations, the more that time passes and
experience is gained.
