In order to measure elastic responses of a ship in waves, elastic models were designed. Two design concepts were made use of. One is to fabricate the model by using synthetic resin as a strength shell and foamed urethane as a material shaping body. The other is to use aluminum bars as a strength membrane while foamed urethane being used for shaping the hull form. The characteristics of the materials were verified through various kinds of tests to find them satisfactory for the models. Three models were made b these two concepts; a container ship model and a high speed patrol ship through synthetic resin method and a bulk carrier model through aluminum bone methods. Over all elastic characteristics of the models were examined by static bending test, hammering test and so on. The results show that they have good correspondences with ships on the similarity laws. Measured bending moments in waves in model basin were compared with the results of the sea trials. It is shown that the agreements between them are excellent and the model can tell us on the differences in structural responses of each type of hull forms.
