This is the second paper on the “Waveless Hull Form” which has been developed at the Tokyo University Tank during last two years. In the first paper the tank experiments on the bulbous bow have conclusively proved that the wave-making characteristics of the bulb can be practically represented by an isolated point doublet. The free wave due to a point doublet has just the inverse phase against the wave due to a continuous source distributian. The latter singularity corresponds to a main hull, and the waves arise exclusively at the bow and the stern. Therefore, if the waves due to the bulbs fitted at the bow and the stern most effectively interfere with the waves due to the main hull, the situation of the “Waveless Hull Form” is to be realized. That is perfectly possible with the combination of the bulbs and the main hull, best adapted to the designed speed. Thus we can realize the ideal of the “Waveless Hull Form”, which means the “Wave-Making-Resi stanceless Hull Form”. The present author began with the investigation on the characteristics of the phase and the amplitude of the waves due to the bow bulbs with the newly designed mathematical hull forms, and attained to the “Waveless Bow” with the two models : one being a fine model C-101F and waveless at the speed of Froude's number 0.26, and the other a full model C-201 F2 and at F. n. 0.27.
