Number of small car ferries are in service between islands in Japan, and many of them are a mono-hull type double ender because of the saving time on boarding and landing. Recently, by the trend of speed up in the sea traffics, these ferries are also required in higher speed running. However, the high speed running of ships and crafts often give the severe damages to the small fishing boats or oyster rafts, because the running accompany the large wave. Under these situations, a new idea of catamaran is investigated of which outer shells are wall-side. The essential feature of this catamaran is to lock the wave making phenomena between demi-hulls as much as possible and, if possible, to decrease the locked waves by the interference of wing or pod in which the propulsion unit is housed. For the practical point of view, a mono-hull type double ender ferry is selected as mother ship and two catamarans (ordinary and wave-locking) are designed based on the mother ship. And for these three ship models, resistance tests and wave height measuring tests are carried out. The main results are that the wave-locking catamaran has the optimum distance between demi-hulls at which the residual resistance is minimum and the waves behind A.P. made by wave-locking catamaran are clearly smaller in comparison with ones by mono-hull type. The theoretical calculations concerning waves on the two catamarans (ordinary and wave-locking) are performed. In the calculation, famous Wigley model is used as the mother ship. The results of calculations support the results of experiments.
