Abstract: The article presents the results of calculations of the hydrodynamic pressure field around the ship as a space function, calculated by boundary method. Calculated hydrodynamic pressure field is compared with the measured field for a special vessel, the description of the shape of the hull is approximate. Presented results of the calculations have been obtained using single layer, that is the source of continuously distributed. Constructed using this method, a program called SHiPP will be complemented by the method of calculating the double layer, that is the dipoles of continuously distributed. Calculations for the signature of the ship at a constant speed obtained polynomial dependence of the maximum underpressure at ship, depending on depth. A good conformity of calculated and measured hydrodynamic pressures. The error is less than 1-2 percent for the underpressure. For overpressure is of the order of several percent.
