PREDICTION OF THE WAVE RESISTANCE OF SHIPS BY STATISTICAL ANALYSIS

A method to predict the wave resistance of ships at the preliminary design stage is presented. The effect of principal dimensions and prismatic curves on wave resistance is investigated theoretically. From the investigation an estimation formula is obtained statistically by combining the theoretical formula of wave resistance and test results of ship models. Examples of estimation of wave resistance of various ship forms, e.g. a a cargo liner, a general cargo ship and a passenger cargo ship, are given. The formula is found very useful for preliminary design of ships.
