The effort of analyzing the ship motion by the slender body theory began around the early sixties. Since then many theoretical attempts have been examined for their validity, and the theory has become refined. The slender body theory for the ship motion has in itself several length scales, for instance the wave length, ship dimensions and ship speed, and so forth. The assumption of the order of magnitude of these length scales governs the structure of the theory. And the theory has developed according to the effort of making the order of magnitude of the length scales changed. It can be said that the slender body theory is a more rational theory than the strip theory for ship motion. And the strip theory can find its position in the hierarchy of the slender body theory. This situation will be made clear when investigating the slender body theory under the assumption that the wave length generated by ship motion is same order as ship beam. In this paper, by systematic and consistent treatment, the slender body theory of many kinds of assumption of the parameters are discussed.
