The invention relates to a ship-ship interaction hydrodynamic test device and a test method, and belongs to the technical field of a ship design. The device comprises a bare ship body model I, a bareship body model II, a planar motion mechanism, a trailer side bridge, a pool trailer and a four-component sensor. In the invention, a planar motion mechanism is used for testing a maneuverability hydrodynamic force of a water-jet propulsion ship model, the other water-jet propulsion ship model is erected beside the ship model, and by testing the hydrodynamic force of the ship model in different control states of two ships, a reference basis is provided for ship control safety, and engineering guidance is provided for safe ship-to-ship distance running. The testing device provided in the invention is simple in structure and reasonable in testing method, and can accurately obtain the ship-ship mutual interference hydrodynamic force of the water-jet propulsion ship model and obtain a corresponding interference force derivative. Meanwhile, an influence of jet wake flow on the ship-ship mutual interference hydrodynamic force of the water jet propulsion ship model can be tested and analyzed,and an application prospect is very wide.
