This paper analyzes the motions of a catamaran advancing at a constant speed in arbitrary heading waves. The mathematical expressions of the hydrodynamic coefficients and exciting forces are derived. These mathematical expressions apply not only to catamaran, but also to monohull, and can be extended to multihull. In analyzing the hydrodynamic and exciting forces, the hydrodynamic interactions between the two hulls are considered in addition to the effect of forward speed and aftermost section. These hydrodynamic interactions should not be neglected for the motions of catamaran.
