• This paper describes the attempts made in Nagasaki Experimental Tank to improve the accuracy of flow measurement in high wake region of single screw ships, Noticing strong downward velocity in the high wake region preliminary approach was made by modifying analysis method with extension of calibration range and by inclining the probe towards flow direction. The results indicated that the normal use of a 5-hole pitot probe (set in horizontal direction) does not yield accurate data of downward velocity component. As a next step an 8-hole pitot probe was developed incorporating a 'normal' and an 'inclined' probe, and it proved to be convenient for measurement of the flow at the propeller plane. Effect of wake peak values on propeller vibratory forces is examined and significance of choosing accurate measurement data is discussed.
