摘　　要：通过分析拖网渔船在作业时所受的阻力 ,探讨渔具阻力对拖网渔船的稳性、横倾角和吃水的影响。结果表明 ,拖网渔具阻力的作用使渔船的初稳性高度降低 ,产生可达 4°的横倾角和 0 .7m尾倾。Through analysing trawler resistance at working, research effect of trawler on stability of fishing gear , angle of heel and trim, it can be concluded that initial stability height of trawler decreases and caused 4° angle of heel and 0.7 m trim by stern. On this basis, Safe operation of trawler has also been analysed.
