Abstract : The report presents the results of an analysis of data obtained from stereophotographs of the wave pattern in the wake of a ship model moving at constant speed (V/square root of gL = 0.367). The data were used to compute the wave resistance of the model following a procedure suggested by Eggers. Several methods of carrying out this procedure are discussed and the numerical results from two of them are compared with the residuary resistance obtained from a towing test. The wave resistance obtained by a least-squares method of analysis is quite close to the residuary resistance. (Author)
