Abstract

It is considered that the weather and ocean such as the wind, the tidal current and the wave are the most important factors to a sailing ship. In this paper, the numerical calculation methods of the tidal current, the wind and the wave are proposed in the coastal sea area. In second, the numerical navigation system is investigated by the simulation. The purpose of this paper is to propose the numerical estimation methods of weather and ocean, and to discuss about the simulation of numerical navigation for a sailing ship under effects of numerical weather and ocean. The simulation of numerical navigation to a sailing ship is carried out under the effects of numerical weather and ocean. The proposed numerical navigation is very effective for the estimation of the ship position for a sailing ship. It was found that the numerical navigation system is possible to introduce to the weather routing system in the coastal sea region in future.
