The ITTC-78 power prediction method can be divided into three groups of procedures: R TS - procedures, T BS - procedures and the Q BS - procedures. Only the Q BS - procedures were analyzed in the paper [7] where a new approach to the determination of Q BS and n S parameters was given. A new idea of the equivalent open propeller is the basic difference between the Q BS - ITTC procedures and the new Q BS - procedures called JH ones. This paper presents the numerical results of power prediction for a selected ship, obtained with the use of the zero version (0-JH) of the new method (in its 0-JH3 variant). A comparison between the ITTC-78 method, 0-JH3 method and sea trial results was also given.
