Research on the Matching of the Trawler Ship Machine and Propeller based on Self-propulsion Test

In this paper,through the ship model self-propulsion test of trawler,researched the interaction between the ship hull and ducted propeller,good matching performance between hull,machine and propeller,It fore—cas t ed the ship performance,determined the relationship betweenmain engine power,speed and the speed of the ship,reached the shipspeed prediction,to meet the design requirements of the task.
