Abstract

SUMMARYSummarizing we state: Theory has given a broad picture of the wave resistance phenomena over the whole speed range. It has indicated the sensitivity of resistance to small changes of form in some speed ranges and thus given a useful guidance to model technique. Calculated resistance curves for a large variety of normal ship forms will soon be available. The quantitative agreement between calculated and measured resistance data is reasonably good under certain conditions, but should not be overemphasized. Theory fails to give correct values for full ship forms at low speeds. Although much is left to be done on the influence of the actual proportions of the ship and still more of viscosity effects on wave resistance, theory proves to be an indispensable tool of research and it is expected to become a valuable help in design.A rather comprehensive list of references can be found in reference [3]. The present list does not acknowledge properly, among others, the decisive contributions made by Havelock and Wigley in this field.
