Following to the preceding report, the author has solved numerically the wave pressure problem acting on parabolic waterline ships with infinite draft fixed amongst waves. Firstly, the steady drifting force has been obtained when the wave propagates at right angle to the ship's logitudinal center line. (Fig. 4, Table 3.) Secondly, the surging force has been obtained in these cases, that is, when the wave propagates parallel to and at right angle with the ship's longitudinal center line. (Fig. 8) For this calculation the wave height around the ship surface is necessary and calculated. (Fig. 5, 6) When the wave length tends to infinity we are to remind a virtual mass effect of the ship, remembering Rayleigh's approximation in such case of other wave problem. It is observed that the consideration for this connection leads us to the appropriate result of the surging force in the range of fairly large wave length.
