The 'Catamaran Stern' ship has a conventional fore part and an unusual stern form of catamaran type. This type of ship is expected to achieve very high fuel-saving, without experiencing propeller cavitation, hull vibration due to propeller exciting force, air suction in ballast condition and other problems that are apt to occur to a ship with a single large low-speed-rotation propeller. In order to confirm the fuel-saving effect of this hull form and to better understand the design problems involved, we repeated the trial designing and tank testing. As a result, we have confirmed that the 'Catamaran Stern' ship saves 15 % more fuel than the conventional single-screw ship with the same principal dimensions, deadweight, and service speed.
