The interaction between haed sea waves and a slender ship is analyzed by the slender-body theory under the assumption that the wave length of the incident wave is of the same order as the beam of ship. The main purpose of this paper is to derive a solution that is valid at the vicinity of the bow, where the asymptotic solution by Faltinsen showed x^<-1/2> singular behavior. Since the bow part is singular region for the midship solution, the introduction of the bow part near field is effective to obtain a solution which will be valid at the bow. The problem is treated as consistently as possible. The final integral equation turns out to be similar one as Maruo derived. In order to calculate the pressure distribution on hull near the bow, an approximated formula is given and the boundary value problem which has the Helmholtz equation as the governing equation instead of the Laplace equation in the strip method is also discussed.
