In this study, speed performance and operation limit of a high speed ship (HSS) "TSL-A" in waves were estimated. Using the wave data produced by a fine-mesh wave forecast model and the statistical ocean current data, comprehensive weather routing simulations of the TSL-A were performed. The isochrone method was adopted to determine the minimum time route (MTR). From the results of the simulations, the followings were obtained. (1) The MTR of HSS is largely affected by the operation limit in calculating ship's speed in waves. (2) Ship weather routing is very effective also for the HSS if there is wide sea area on both sides of the great circle route to avoid adverse wave conditions. (3) In some wave conditions, the MTR of HSS becomes very sensitive to the departure time. (4) The route optimization not only can shorten the passage time but also can improve the punctualness of operation. (5) The optimum route simulations can be used to determine the speed and seakeeping performance of the HSS to be put into service between the given ports.
