This paper deals with the experimental analysis of the shallow water wave dynamics in a ship in order to confirm the usefulness of the modified Random Choice Method (RCM). A swinging table apparatus is made compact for the using of a small type of servomotor and some sorts of tank models are produced. A series of experiments are methodically carried out to verify the effectiveness of the modified RCM for shallow water problems. The modified RCM can investigate the free surface configurations of shallow water in broad perspective but not spilling breaker or plunging breaker. The hydraulic jump and the standing wave appear almost precisely at T_θ=T_1 and T_θ=T_3 respectively, where T_1 is the first natural period of rolling for the shallow water and T_3 (=T_1/3) the third natural period of rolling. The existence of the position of a tank where the free surface is not disturbed is also proved experimentally and numerically. As these experimental results, it became known that the modified RCM is valid for the analysis of the shallow water wave dynamics in a swinging tank.
