In this report cavitation experiments on a model of the training ship "SEIUN-MARU" are described from the view point of accurate assessment of propeller induced hull vibration. The present experiments include cavitation observation, cavity thickness measurement and fluctuating pressure measurement. These experiments were carried out both for the conventional propellers and highly skewed propellers as performed in full scale. Results of a systematic series of model experiments are compared with the full scale measurement and discussed. The maximum amplitude of fluctuating pressure at first blade rate induced by the highly skewed propeller reduced 45-65% of that induced by the conventional propeller, while the decrease of cavity volume on the former propeller was not so remarkable. The agreement of the measurement results between model and full scale ship experiments is satisfactory concerning cavitation extent, cavity thickness and pressure fluctuation.
