A practical method is described for calculating the non-lifting potential flow about a slender ship in steady horizontal motion at zero Froude number in shallow water. The present method is some expansion of the previous method for calculating the deep water flows past ship hulls described in author's previous paper. The method utilizes a continuous source density distribution on each surface of the infinite image series of a ship, and treats the normal component v_n (or integral equation for the source density distribution), radial component v_r and circumferencial component v_θ of disturbed velocity as two dimensional problem, and treats the axial component v_x and veloctiy potential φ as three dimensional problem. After the integral equations for the source density distribution are solved numerically, pressure distribution and added mass of a ship under various motions in shallow water are calculated easily.
