We have many experimental and calculated results on the added resistance in head waves. In case of oblique wave conditions, there is not so many, and there is few data on three steady forces-added resistance, lateral force and turning moment. For knowing behaviors of ships in oblique wave conditions, it needs to obtain them. We can calculate the added resistance in oblique waves by Maruo's and Hosoda's theories. But, we have not the theory to obtain the steady lateral force and the turning moment acting on ships with advance velocity. The authors had calculated the added resistance of the blunt bow ship in short waves by the ray theory. By extendinng this method, other two steady forces can be got easily. Results of comparison is shown between calculations and experiments which are carried out in the recutangular basin with the wave maker.
