Abstract : Seakeeping predicts heave, pitch, and acceleration of a designated hull form in regular waves over a range of wave lengths and wave amplitudes. The program is divided into four mainline sections: Part I sets up the input data for the two calculating sections of the program. Part II calculates the simulated added mass and amplitude of the generated waves of the hull form; Part III calculates the amplitudes of heave, pitch, and acceleration; and Part IV plots and curve fits this information. The user has three options of output information; Printed, Plotted, and/or curve fitted.
