| Abstract: | A nonlinear differential yaw equation model of a ship with hull hydrodynamics, screw propeller thrust and auto-pilot force acted on it is established. Wave exciting force and 2-order wave flow force are also taken into account. Considering both ship velocity and encounter angle to waves and auto-pilot parameters as variable parameters, we use numerical integration combined with cell-map method to study broaching attracting basin of ship running in following seas. |

| Keywords: | broaching cell-map attracting basin asymptotical stability |
