A maneuvering mathematical model for Controllable-Pitch Propeller ships with three degrees of freedom is established according to separate modeling theory. Based on Netherlands Ship Model Basin\'s open-water tests, CPP thrust coefficients and torque coefficients in four-quadrant with different pitch ratio of screw and different types of CPP are obtained by using Akima interpolation. Therefore, CPP thrusts and torques are obtained.
