Rotational flows exist in the propeller slip stream in any ships. If any method is developed that can recover the rotational flows (energy loss) efficiently, it will surely contribute to the energy saving of ships. The authors have made efforts to develop a practical apparatus for this purpose and finally developed Kawasaki RBS-F (Kawasaki Rudder Bulb System with Fins, called "RBS-F" hereinafter, patented). To date, RBS-F has been installed on more than 40 ships, mostly large full ships, because of its practical characteristics. This paper describes the development of RBS-F and its application to full scale ships.
