The controllable pitch propeller is often used for ships with multiple operating modes such as fishing boats, patrol boats, tugboats... In this paper numerical method is employed to study the hydrodynamic properties of a controllable pitch propeller. It has diameter of Im, designed pitch ratio H/D = 0.6, the shaft revolutions of 629 rpm and the engine power of 155CV. The achieved results of the article are an important basis to improve the exploitation efficiency and the hydrodynamic performance characteristics of controlable pitch propellers.
