Munif et al. had proposed a 6 degree-of-freedom (DOF) nonlinear mathematical model for predicting extreme roll behaviors and capsizing for a ship in astern waves with a moderate forward velocity. To validate this model, the authors carried out several numerical runs at the condition corresponding to the free-running model experiment by Hamamoto et al. The comparison in time series and capsizing boundaries between the model experiment and the numerical simulation shows a reasonably good agreement. Furthermore, by comparing with the 4 DOF mathematical model excluding heave and pitch motions, it is revealed that the effect of heave and pitch motions can be significant when the wave steepness becomes larger.
