It is presented how to solve the ship surface condition of a displacement ship in steady motion considering the free surface effect. The free surface condition is, of course, linearized by the infinitesimal wave height and slope assumption. The theory is developed, supposing that the combined velocity potential of the double model conception and the free wave term will approximate the exact velocity potential in the equation of the ship surface condition. Furthermore, it is assumed that a beam is small in comparison with a length. The author solved the basic integral equation numerically for infinitely deep struts and obtained source distributions involving the free surface effect, which yielded good results of wave-making resistance and wave profiles.
