Abstract: 1. In this paper the solution of basic equation of ship vibration, determination of frequency, response of ship main dimensions, and hull material quality at heaving is presented. 2. Predominant functions determining vertical frequency, ‘longitudinal distribution of: ship’s mass, surrounding water mass and bending stiffness’, are studied and approximated in series harmonic functions. Minor factors, ‘effect of shear stiffness and gravitational effect of virtual surrounding water’, are considered. 3. Comparison between author model result and those obtained by other methods is presented.
