In order to reduce the amplitude of the propeller shaft vibration, it is useful to apply the hydrostatic bearing to the stern tube bearing.<BR>This paper describes the theoretical and experimental investigations on the reduction of the propeller shaft vibration by using a hydrostatic bearing.<BR>The theory is based on the finite width hydrodynamics.<BR>The calculated results give very good agreements with the measured ones. Also the hydrostatic bearing gives a high degree of reduction efficiency of vibration, which reduces the vibration amplitude to 60-70% of that of conventional type.
