Title: THE WAVE-MAKING RESISTANCE OF HIGH SPEED BOATS - THE SECOND REPORT: SHALLOW DRAFT SHIPS
Abstract: Following the first report, this is a study to search optimum ship forms of shallow draft ships represented by the surface pressure distribution in high Froude number range. A case is considered where pressure is distributed on a rectangle. If the pressure disappears around the edges, it should avoid splashing according to the linearised theory. The conclusion is that the more complex the distribution, the less wave resistance. The splash-free type seems to be optimum, have little dynamical buoyancy and may be called a displacement ship. A Yacht type vessel, which is a combination of a thin and a flat ship, is calculated. The results are not favourable. Lastly, 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.
