The interaction between head 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. Although the same problem has been treated by both Faltinsen and Ursell, the complete explanation of the problem seems not to have been given. Especially, the rational radiation condition is taken into consideration in this paper. The introduction of the concept of the interaction of the elementary waves, which are components of Kelvin ship wave pattern, with the ship hull gives a rational result for the diffraction problem of the steady ship motion. The same idea is also applicable to the problem of the interaction of a slender ship and wave which are generated by a given pulsating source distribution on some part of the body. It has been found that Kelvin ship wave pattern is deformed and the transverse wave system decays in x^<-1> when Kelvin pattern travels along a slender body. And the waves of a pulsating part of hull also decay in x^<-1> when they travel along the rest of hull.
