High speed ships, especially with planning type of hull forms are popular amongst navies of the world. Appropriate propulsion plant configuration has to be selected to provide the desired maximum speed and quick responses. Dynamic response of the ship's propulsion plant is one of the main considerations in selection procedure. Accuracy of dynamic response obtained from computer simulation depends on the accuracy of data, especially the hull resistance and propeller characteristics. This paper discusses the estimation of hull resistance and propeller characteristics of the ship with the help of computer programs and their comparison with full-scale trial data.
