Abstract : Ship wave resistance is defined and a survey of past and present efforts to determine this from a survey of the model wave pattern during a model test is given. A new method is developed using the continuous record of the x and y components of the lateral force exerted on a long fixed vertical circular cylinder by the model wave system after passage of the model. The paper includes theoretical analysis, a description of the technique and equipment necessary, and results of experiments run at Webb Institute on a Series 60 Model and on the A. T. T. C. Standard Model. These findings are compared to the Michell thin ship theory and to other experimental results. The results indicate that the method is a practical means of determining wave resistance in an ordinary ship model tank. Conclusions are drawn in regard to possible areas of future investigation.
