A theoretical method for analyzing the roll reduction by rudder control, either single ship or two ships, is developed in the paper. The basic ideal is when the rudder is operating, the yaw and roll moment will be generated and affect the rolling motion. Using the well developed strip theory which is available for one or two ships advancing in waves, yaw autopilot and roll stabilizing feedback system, can be considered together and a better set of gain coefficients may be predicted priori. It is found that the suitable rudder control indeed can reduce the rolling motion especially at the resonance frequency.
