Abstract : Theoretical added resistance calculations for a ship in regular waves were performed by Maruo's theory. The overall results were applicable to ships with cruiser stern. The theory was applied to 72 hull forms with parametric variations of their principal characteristics. For a test case Maruo's theory yielded similar results to Gerritsma's theory. Theoretical predictions of ship motions by different strip theories were found to affect the added resistance calculations. A computer program for Mauro's theory is presented. An additional computer program allows the determination of added resistance in a seaway from the presented results in regular waves. (Author)
