Six-degree of freedom motion of a free-running model ship in waves was measured at a model ship basin equipped with a moving carriage by using an optical motion measurement system. The carriage can track a model ship automatically by using another system that measures the horizontal movement of a model ship. Measured optical ship motion data are compared with data obtained by a fiber optical gyro to evaluate the optical data validities. Discussion about applicability of the optical measurement system both to the motion measurement and carriage tracking is provided.
