Because of the continuous growth of the quantity of ships at sea in the world, the turning performance of ships has received increasing attention. It is a common method to improve the maneuverability of ships by installing swash plates on rudders, but their installation positions and sizes have an irregular influence on maneuverability. Free-running ship model test is an important means to evaluate maneuverability, but it is very expensive and time-consuming. In this paper, body-force method is chosen to take the place of a real propeller for numerical calculation to distinguish whether the turning performance is improved after installing a swash plate. Numerical calculations and ship model tests are carried out under two different conditions: bare hull and hull with swash plate. The numerical results and the experimental ones match well. The conclusions acquired here can provide evidence that using the body-force method to conduct the numerical simulation of turning motion can not only reduce the amount of calculation largely, but the accuracy of the calculation can also meet the needs of projects.
