The present results reveal that the hydrodynamic model and roll reduction technique developed here can be regard as an efficient tool for naval architects to analyze the ship maneuvering behavior with roll reduction by rudder control in waves at the preliminary design stage 本文所发展的数学模式与减摇方法可用于初步设计阶段，来评估船只在波浪中进行操舵减摇的操纵性能。
