For our sustainable development, it is required to reduce CO_2 emission also in the field of the shipping. There seems to be a possibility of reducing CO_2 emission by improving the navigation. The conventional weather routing system provides a minimum time route using the isochrone algorithm. However, from the environmental point of view, a new weather routing system aiming to reduce CO_2 emission must be provided. Therefore, in order to reduce CO_2 emission from ships, a new weather routing system for a novel sail assisted ship is developed. The new system has features that not only choose sea route, but also adjust ship speed. In the calculation of the new system, a bulk carrier of the transpacific route is selected as the novel sail assisted ship. Equilibrium equations of longitudinal force, lateral force, yaw moment and heel moment are solved to estimate ship speed in actual seas. From the numerical examinations, it becomes clear that the new system reduces 17.4% of CO_2 emission.
