Maruo's linear theory for the added resistance of a ship operating in head seas is placed into a form which allows numerical evaluation on a computer. To establish the validity of linear theory, a comparison is made between the predicted theoretical values of added resistance and the measured values obtained from experiments on a Mariner model and Series 60 models. The results of the comparison indicate that linear theory does predict the increment in resistance with a good degree of accuracy in the range of higher Froude numbers. Having demonstrated the usefulness of linear theory in predicting added resistance, a computer study is carried out to evaluate the added resistance of 'U' and 'V' shaped hull forms. The study shows that the V-form has 10 to 20% less added resistance than the U-form in the normal ship operating ranges.
