摘　　要：论述全回转拖轮的阻力性能特点,通过船模试验结果验证全回转拖轮在自航状态时兴波阻力是总阻力中的主要成分,结合有关实船论述船舶主尺度、船型系数及线型对阻力性能的影响,阐明如何设计和建造阻力性能好的全回转拖轮。The resistance characteristics of the Z-propeller tug is analyzed. The experimental results of model test verified that the wave-making resistance is the main part of the total resistance. Taking a real Z-propeller tug as an example, this paper discusses about the influence of principal dimensions, hull coefficient and forms upon the re- sistance performance in order to design and build a good Z-propeller tug with fine resistancepefformance.
