Recently transportation services of passengers and cars by fast car-ferries over 40 knots have been rapidly developed in the world. In this paper a new general cost model including factors of comfort, riding comfort, convenience, exhaustion and safety as well as fare and traveling time is proposed to predict the share of fast car-ferries in total demand of passengers between two places. Using the model and a cost analysis for operation, the competitiveness of fast car-ferries can be evaluated with other transportation system. As a case study the feasibility study on a fast car-ferry service between Osaka and Tokushima is carried out to find that fast car-ferries can obtain a share of 40-50% in total demands of passenger between the cities and that the service would be promising.
