Parameterized hull model allows to consider several vessel projects variants from the point of view of sea keeping, stability, cost efficiency and other criteria for choosing the most optimum one. Besides, it allows changing some significant features of the project if its considerable service conditions are changed, on the initial designing stage, or, if it’s a serial production, modify project in a short time and to avoid a significant errors.

Key words: parameterization, computer-aided design.

The paper studied the effect of shape of the hull on the kinematic parameters of the longitudinal pitching and wave bending moments for ship hulls with different coefficient is – Cb, the provisions of the abscissas center value – xc and abscissa Center Square waterline – xf. To this end, we used program for computing the longitudinal pitching "MOTION", developed by the authors, as well as routine to automatically generate various forms of the ship’s hull, depending on the xc, xf through analytical relationships. The results obtained allow us to give recommendations for the design of the hull forms with regard to its behavior in the rough sea surface.

Key words: design, the hull, the wave bending moments, the kinematic parameters of pitching, the longitudinal pitching, the standard deviation.
