In recent years, the highly skewed propellers tend to be used for the prevention of the growth of ship vibration and noise. On the other hand, however, the blade strength of the highly skewed propeller under the ship operating condition has not been measured up to the present time, in spite of the need for the judgement on the blade strength. Therefore, the authors measured the blade stresses of the highly skewed propeller which was fitted on a Pure Car Carrier.<BR>After analyzing the measured data, it has been found that the maximum principal stress induced on the pressure surface of the blade at the point of 0.4 R with 90% camber length from leading edge became maximum in value when the propeller chip clearance became minimum.<BR>Furthermore, the measured principal stress mode within one revolution has been compared with the calculated result by the FEM analysis and the both have a similar tendency in the mode.
