This paper deals with the comparison between the calculated and measured ΔC_<wA> of the Waveless Stern, where ΔC_<wA> means the difference of the wave-making resistance between the models without and with the stern bulb.The observed position of the stern flow separation (named X_S) is presented, together with the comparison between the observed and the calculated area of separation by Buri's method.The conclusions obtained are as follows.(1) The reduction factor β for the stern wave of the finer model C-101 falls by fitting the stern bulb, while for the fuller model C-201,it keeps same.(2) The area aft the observed X_S seems to be an actual separation area. The time-mean and the fluctuation are affected according to the phase (and amplitude) of the bow wave observed at the vicinity of the separation point.
