The Maneuverability of twin-propeller twin-rudder ship is reported connecting with previous paper. In the previous paper, it was discussed that the peculiarity of twin-propeller twin-rudder ship appeared in the interaction among the hull, propeller and rudder. Therefore, in this paper, the interaction is discussed concerning with two kinds of hull form. The results of this study are following ; (1) The wake at the propeller is effected by hull form, especially by the type of propeller shaft suspension. (2) The type of propeller shaft suspension also has an effect on the rudder characteristics and the rudder behind the hull in oblique motion is much effected. (3) The characteristics of unbalanced hydrodynamic force caused by propeller running is strong comparing with single propeller ship, especially in oblique motion.
