heal.abstract	The prediction of the added resistance of ships in waves in view of alternative theoretical approaches and practical applications is herein addressed. Two basic methodologies are generally employed for the prediction of the added resistance in waves, namely far and near field methods, in connection with alternative seakeeping potential theories in the time and frequency domain. Inherent problems in the predictability of employed alternative methods prove to be the accurate prediction of the peak values of added resistance, corresponding to incident head wave lengths slightly over one ship length, the prediction of the asymptotic values for short wave lengths and computational efficiency (satisfactory accuracy at reasonable computational time). Implemented approaches are herein validated on the basis of typical case studies for various hull forms and useful conclusions regarding the accuracy and efficiency of the employed methods are drawn. © 2010 The Royal Institution of Naval Architects.	en
