In this study, an advanced weather routing system using INMARSAT data communications has been developed, and the onboard experiment has been carried out since 1990 with the container ships plying Japan-California route. After the first experiment performed in Nov. 1990-Mar. 1991, the system has been improved mainly in the following points. (1) The data communication speed was increased up to 4,800 bps by using new INMARSAT terminal with data/fax line, which enabled us to send a large amount of information such as surface pressure charts to a ship. (2) The function to evaluate the captain's route was added to the system. (3) The wind/wave data set based on 10-day numerical forecasts by the U.S. National Meteorological Center was prepared for the optimum route calculation. Using the improved system, the second onboard experiment was performed in Nov. 1992-Mar. 1993 and the effectiveness of the system was thoroughly demonstrated.
