This report describes colliding tests with free floating model ships. The two ship models, referred to as the struck ship and the striking ship were used to the tests for the movement of colliding ships. The shock responses for ship models were measured using boxtype ship model with two load cells. The positions of ship models obtained by the position analyzer with VIDEO camera, and the camera was set on the tower which is about twenty meters height above water surface. The results of experiment were as follows; (1) The additional mass due to water with the struck ship was proved 0.4 times its ship's mass for a few second after collision. (2) When the colliding ship collided with midship of the struck ship, the ship was moved in parallel with the position before the shock after collision, and this state is indepedent of colliding angles. At the collision to other points, the struck ship was horizontally rotated for the center of gravity, and it was varied parallel movement after a short times. (3) The calculating values of the equations from the conservation of momentum agreed with experimental values.
