It is well known that a screw propeller generates free vortexes called tip vortexes and a hub vortex in its slipstream. In this paper, PBCF (Propeller Boss Cap Fins) which diffuses and weakens a hub vortex by changing the flow near by propeller boss cap is proposed in order to enhance the efficiency of ship's screw propeller.<BR>The research and development of PBCF was carried out through Flow Visualization, Propeller Open Test, Self Propulsion Test and On Ship Test to make the PBCF practical.<BR>As the result of various experiments, gains of 3 to 7% in propeller efficiency, gains of approx. 2% in self-propulsion efficiency of 7 m Model ship and gains of approx. 4% in terms of power output on 44, 979 Gross Tonnage PCC “Mercury Ace” were obtained. These data lead us to believe that PBCF can be excellent energy-saving device with its simple structure.
