摘要:: 为了研究荷载位置变化对龙骨帆船大倾角稳性的影响程度，采用可变质量位置变化对大倾角稳性影响的计算方法，依据Maxsurf软件与检验规范，并以一艘10 m休闲龙骨帆船为例，获得不同人员布局在满帆操作下的安全操帆风速，计算复原力臂差值，得到影响程度的最大差异可达到10%-33%的结果。研究表明，设计、检验和驾驶龙骨帆船时，要注意人员布局对帆船稳性的影响。

Abstract:: The study was carried out to study the influence of variation of the load position on a large angle stability of a keel boat.A leisure keel boat in length 10m was selected,the software Maxsurf was employed and the test specification was conducted to calculate the large angle stability via the method of variable weight position change.It shows that the maximum difference of righting lever was about 10% to 33% at the security sail wind speed under the full sails.Conclusions were drawn that the design,test and driving should be noticed while concerning the impact of the personal accommodation space on the stability.
