摘　　要：小水线面双体船(SWATH)由于具有良好的船舶快速性、耐波性、稳性和效率高等特点,已经成为新船型的代表。根据小水线面双体船的船型结构特点,在操纵运动数学模型的基础上,充分考虑小水线面船的结构特点和双体、双桨、双舵之间水动力的相互影响,采用细长体理论计算了附加质量、附加惯性矩和线性水动力导数,编制了双体船操纵运动预报程序,并结合实例对SWATH的操纵性能进行了预报。SWATH is a new kind of ship types due to its excellent powering and seakeeping performances as well as stability. Taking the characteristics of SWATH ship form and the hydrodynamic interaction among twin bodies, twin propellers and twin radders into consideration, its hydrodynamic force derivatives and added mass as well as added moment of inertia are computed based on theory, of slender body, the program of predicting SWATH maneuverability is compiled using the MMG maneuvering model at sea and illustrated with an example.
