Once a first attempt has been made in order to determine the main parameters of a new design and a draft of the cross sections area drawn, the designer, by means of some regressive models proposed in this paper, will be able to calculate the values of the total resistance volumetric coefficient [CTV] and also to choose, since the first stage of his design, among different alternative proposals under consideration.
The results of some analyses carried out on towing data for mediterranean fishing vessels are presented here; it is particularly pointed out the originality of the approach by means of the statistical regressive tool allowing a careful reading of the close link between the wave resistance of a displacement hull and its curve of the cross sections area, by which appraisals of CTV affected with a very small intervals of confidence could he done.
