The hydrodynamics, the kinematics, and the effects of slamming are discussed. Present methods of ship-motion prediction are used to study the conditions which lead to slamming of ships in head seas. If wave length and wave height are given as well as the length, draft, and speed of a ship of normal design, the possibility of the emergence of the forefoot can be predicted from a graph. An iterative procedure is described to estimate slamming force, acceleration, and pressure distribution on the bottom of a slamming ship. General discussions and results are presented in the body of the text; derivations and detailed computations are given in appendixes. (Author)
