Abstract : This technical memorandum discusses the implementation of a near-field method for prediction of added resistance in the Strip theory program SHIPMO7. Comparisons with experimental data for Series 60 hull forms and a frigate indicate accuracy similar to other methods, including three-dimensional codes. Advantages of the current method include computational efficiency, robustness, and reasonable values for added resistance in following seas. Inclusion of the SHIPMO7 dynamic swell-up option improves accuracy of added resistance predictions for the frigate but degrades accuracy for the Series 60 hull forms.
