With a ship model of single-screw high speed container ship, resistance and selfpropulsion tests in regular and irregular head waves were carried out in the Experiment Tank of Osaka University. The experimental results of ship motions and resistance increase in regular head waves are compared with the results obtained from the theoretical calculations. The significant amplitudes of heave and pitch and the mean increases of resistance, propeller thrust, torque and revolution measured in irregular waves are compared with the values which are predicted from the response operators obtained by the experiments in regular waves and the wave spectra by applying the linear spectral method. The self-propulsion factors in regular and irregular waves are analysed by assuming that the mean characteristics of a propeller are identical with those in still water.
