The paper presents a set of experimental results for a group of podded propellers under different cavitating condditions. These model propellers had the same blade sections but different hub geometry so that the comparative study was performed to identify the effects of hub taper angle and propeller configuration on the performance under cavitation. It was concluded that increasing the propeller hub taper angle decreased the efficiency both in pusher and puller configurations at all cavitating conditions. It was also concluded that in general the puller propellers had a higher efficient than the pusher ones.
