This paper consists of two parts. The first part is on the outline of renewed large forced motion mechanism to be used in the maneuvering test on submerged body and surface ship model in the large towing tank of Meguro Model Basin, and model test method. The second part is on the construction of empirical estimation method of hydrodynamic derivatives of two-dimensional linearized equation of longitudinal motion of submerged body utilizing the test results of 37 models of various hull forms and their about 250 model configurations. The empirical estimation method is summarized in functional forms. The hydrodynamic derivatives of hull are expressed as function of equivalent length to diameter ratio, and the contribution of control surface and propeller to the hydrodynamic derivatives are expressed by interference coefficients as function of diameter to span of exposed control surface ratio and propeller diameter to hull diameter ratio, based on their open water characteristics respectively.
