In the last years there is an increasing demand for better maneuverability and dynamic positioning of special ships and floating constructions such as supply vessels, fishing vessels, drilling rigs and other ships exploring the sea. Ducted propellers are very useful for these applications. Polynomials for Thrust and Torque coefficients as a function of the advance coefficient J and pitch ratio P/D are published by MARIN (former NSMB) and are in the appendix. With the use of these polynomials, a computer program was written in Fortran77. The program was used in the preliminary design. For the final design more advanced methods should be used.
