金枪鱼围网渔船的快速性分析

Analysis of resistance and propulsion for tuna seiner

在搜集大量金枪鱼围网渔船资料的基础上，对金枪鱼围网渔船的快速性进行了分析，认为金枪鱼围网渔船的快速性应是在不影响捕捞作业性能所要求的回转性情况下考虑的。同时对棱形系数、宽度吃水比、浮心纵向位置、球艏的参数等提出了建议。

Based on a lot of collected data about tuna seiner, the analysis of resistance and propulsion is executed. It is considered that the resistance and propulsion should be counted on the occation that the requirement of turning ability for tuna seiner fishing is not affected. Some propositions for prismatic coefficient Cp, ratio of breadth to draft B/T, LCB, and parameter of bulbous bow etc, as well as the measures for improving resistance and propulsion are discussed.
