The invention discloses a ship seaworthiness tester which comprises the components of a pair of vertical column racks, crossbeam racks which are arranged between the pair of vertical column racks, a seaworthiness testing device and a following brake device which are arranged on the crossbeam racks. The seaworthiness testing device utilizes a linear motor according to a magnetic suspension principle as a controlling and measurement mode, thereby measuring the motion attitude and added resistance condition of a ship model in the wave at conditions of ultralow damping and no other restraining conditions except for yawing and swaying. The following brake device utilizes the following principle of a linear motor. Through converting pneumatic cylinder movement to mechanical clamping, and clamping and loosening a track by a rail clamp, the ship model is started and stopped in the wave. The ship seaworthiness tester realizes accurate measurement for the seaworthiness state of the ship in a simulated wave.
