Simulations of zig-zag maneuver and crash astern in regular waves were carried out. The simulation model used for the stopping maneuver takes only wave drift forces into account to usual maneuvering model in still water. On the other hands, the model for the zig-zag maneuver includes wave-induced motion effects in addition to the wave drift forces. In this paper the validity of the methods are confirmed through comparison with free-running model test results in head and beam waves with various wave lengths for SR108 container ship model. It was found that the simulation methods can roughly predict the zig-zag and stopping maneuvers in regular waves, although there is some room for improvement. It may be needed to make more rational hydrodynamic model or improve the calculation accuracy of wave drift forces.
