The unsteady wake wash generated by a high speed vessel with decelerated motion is numerically investigated. This situation may be similar to that the vessel reduces the speed in the harbor/channel. By means of a time domain panel method based on the potential theory, the unsteady wash is simulated in deep and shallow canals. Propagation process of the wake wash generated by the vessel is realistically demonstrated: the waves made in the steady moving period pass and propagate upstream after deceleration and stop of the vessel, and the waves become considerably large when the vessel decelerates from the vicinity of the critical speed in shallow water. There is a possibility that such the unsteady wash influence the facilities of the harbor. The present calculation method is useful for analysis of the unsteady wash.
