. Analysis of wave resistance. Ship resistance. 80 c. Assumption of a fixed position (neglect of bodily rise or sink and trim). d. Assumption of a small height-length ratio of waves created by the ship including neglect of the ship form above the water when computing pressure. ACKNOWLEDGMENT This report presents only a skeleton of the subject; by studying the numerous references which, however, do not include important experimental work, it is possible to fill up to some extent the rather sketchy picture. Further, it is hoped that some of the projects now under way at the David Taylor Model Basin will lead to broader applications of the theory. This part of the re- search work, due to its magnitude, must be carried out by large institutions; the development so far has been hampered by the fact that individuals inter- ested in the problems have only occasionally found the necessary support. The present investigation has been initiated and sponsored by the Director of the Taylor Model Basin, Rear Admiral CO. Kell, USN, the former head of the Hydromechanics Laboratory, Captain Forest, USN, and the Chief Naval Architect, Dr. Todd, to whom the author wishes to express his sin- cere thanks. Dr. Todd's help was essential in completing this ample report. APPENDIX 1 THE EQUATION OF THE SHIP SURFACE The axes are chosen as shown in Figure 1. Then the equation of the hull surface may be written y = ± y(x,z) [1]. Figure 1 - Axes of Reference.
