A procedure for calculating the irrotational flow about a double ship model, by solving a Fredholm integral equation of the first kind for a centerplane source distribution, is described. The special problems of determining the curve in the centerplane bounding the source distribution and of smoothing sharply peaking integrands, to improve the accuracy of discretization of the integral equation, are treated. Application to ellipsoids, for which the results of the calculations can be compared with an exact solution, and to a ship form with parabolic lines, for which experimental data are available for comparison, indicate that satisfactory accuracy can be obtained by the method.
