Following the first report, this is a study to search optimum ship forms of shallow draft ship represented by the surface pressure distribution in high Froude number range. At first, the case in which the pressure distributes on a rectangle are considered. If the pressure vanishes around the periphery, there is free from the splash by the linearized theory. In this case also, the more complex the distribution, the less the wave resistance becomes, so that the distribution may be taken simpler. The splash-free type seems to be optimum, have little dynamical buoyancy and may be said a displacement ship. Secondly, the yacht type which is a combination of a thin ship and a flat ship are calculated but the result is not favourable. Lastly, the cases in which the distribution plane is not a rectangle or symmetrical are considered and it is found that the wave resistance increases considerably in such cases.
