%X A new weather routing method is proposed that accounts for ship maneuvering motions, ocean currents, wind, and waves through a time domain computer simulation. The maneuvering motions are solved by differential equations of motion for every moment throughout the voyage. Moreover, the navigation route, expressed in terms of a B?zier curve, is optimized for minimum fuel consumption by the Powell method. Although the optimized route is longer than the great circle route, simulation results confirm a significant reduction in fuel consumption. This method is widely applicable to finding optimal navigation routes in other areas.
