At present, various types of high-speed ships are being developed, though, there are still lots of unknown problems in their fluid dynamics aspects. By dealing with semi-displacement type mono-hull ships which have a majority in high speed ships on service, in this paper, tank test problems are discussed and also their fluid dynamics characteristics are investigated on various factors used in the power estimation for an actual ship, mainly by means of model ship experiments. Experimental investigations were carried out on appendage resistance, air resistance of above-water hull, effects of oblique flow and its cavitation on propeller characteristics, scale effects of some resistance components and running condition, and so on. The horse power of an actual ship which is estimated by making use of the results mentioned above is compared with the result of speed trial test in full scale.
