Relaying on wind driven, sailing vessel is a kind of self-navigator which carries out different types of missions in the complex ocean environment. Survey, investigation, freight and other various tasks are capable of being completed by AUSV(Autonomous Unmanned Sailing Vessel). Differing from general USV (Unmanned Surface Vessel) which must carry lots of battery and fuel, AUSV can use wind power merely. Better still, it has more advantages in the mileage of voyage. To solve the problem caused by energy shortage and environmental pollution, it is very important to research on navigation process and to carry out autonomous voyage, which is of great significance to our country's increasing demand for navigation. At first, the stressed sails of a ship are studied in this paper and a separating model test bed is built in three directions including lateral, longitudinal and yawing oscillation, which establish the MMG three-degree-of-freedom motion model. Combining with the model of force on sails and the model of MMG, the motion model is well established. Runge-Kutta methods are used to insure accuracy and reliability.
