(eds.), Multidisciplinary Approaches to Coastal and Marine Management. Journal of Coastal Research, Special Issue No. 116, pp. 593-597. Charlotte (North Carolina), ISSN 0749-0208. The loss of stability have been regarded as a major cause of marine accidents in small ships which have continued to increase over the last decade. In most them, it is known that a strong hull load generated by a sudden wind attack often causes small vessels to capsize. In this regard, it is necessary to analyse the effect of wind load on ship motion in order to operate them safely. Therefore, the present paper aims to develop a procedure to assess the effect of wind loads on the motion of small ships. Further, the present study includes the numerical results under three conditions: wave only, uniform wind speed, and the NPD wind model. Details of the proposed procedure are presented in a flow chart. The applicability is demonstrated using an example of a 9.77-ton fishing boat under sea state five. Wind loads acting on the fishing boat were estimated in the authors' previous paper. The numerical analysis was performed using AQWA.
