This paper presents a numerical approach for steady ship-wave problem, which is based on extension and modification of Dawson-type Rankine-source method in order to utilize arbitrary topology of free-surface panels. In this 2nd report, the main emphasis is placed on application of the present method to blunt-nose body and consideration of nonlinear effects into the free-surface boundary conditions. The computational results are presented and discussed for surface piercing NACA0024 foil, and Wigley and Series60 C_B=0.6 ship models including detailed comparisons with experimental data. It appears that the present method adequately predicts free-surface flows around blunt nose, and introduction of nonlinear free-surface effects clearly improves linear solutions especially for forebody wave fields.
