In the previous paper, to prevent the ship separation from a quay wall, we proposed a system where the water pressure resulted from the difference of the water level of both ship's side was utilized. We would like to name the system "the prevention system of ship separation from quay wall". In this paper, we carry out model tests under wave action in order to investigate the behavior of the ship moored by the system. The obtained results are summarized as follows: (1) As the direction of the system's force agree with the sway, the sway becomes small. Moreover, subharmonic motions in sway do not occur because the ship always moves within the fender deflection. In the same reason, roll motions are also small. (2) The direction of the system's force intersect at right angles with heave, the degree of decrease of heave is smaller than the others.
