The ship maneuverability has been described with the first order linear equation or the second order linear equation. However, we are under the necessity of the adoption of the second order equation with a non-linear term as the mathematical model of the ship maneuverability, especially in case of full ships. This mathematical model is expressed by [numerical formula] This paper relates a new approach to the parameter identification of this mathematical model. The authors propose the adaptation of the parameter optimization method to the above problem. The outline of the method may be described as follows; the response of mathematical model to which the values of parameters are provisionally given is compared with the measured response of real ship, then the values of parameters are corrected with the particular criterion, and these procedures are repeated. In this paper, the result of analysis applying this method to the motion of real ship is described. Moreover, the authors wish to investigate the applicability of the second order non-1inear equation to the ship maneuverability.
