• Outer and inner expansions are formulated on the basis of"Rational Strip Theory"^<1)> for slender floating body motions due solely to the incident wave. More precisely, since the detail of a slender body is lost in a farfield, farfield potentials are assumedly represented by lines of pulsating source and/or doublet, and their densities are determined by matching with nearfield potentials. This scheme readily results in three dimensional diffraction as well as radiation potentials which are valid in a far-field. Unlike non-rational strip theories, wave pattern, exciting force, drifting force, etc are all available in a three dimensional sense, since throughout the analysis all problems are discussed in terms of three dimensional velocity potentials. Measurements of wave heights and exciting forces manifest the respective validities of the farfield diffraction and radiation potentials obtained here, and substantiate that these potentials are dependable, at least, up to a wavelength as long as the body.
