This paper presents a new method to construct statistically a practical estimate formula for the form factor. Many formulae are available to estimate the form factor being based upon principal particulars and hull geometries. The rusults of application of those formalae to our hull forms have not necessarily shown satisfactory accuracy. Therefore an attempt to obtain mora accurate and reasonable estimate formula was made by utilizing the statistical approch. Applying the minimum AIC estimate method, the parameters which consist of the estimate formula were selected under the explicit criteria of selection. Three kinds of formulae were made, namely for full ships, fine ships, and all kinds of ships respectively. The estimated results of the form factor by the formulae obtained in this paper show fairly good agreement with the measured quantities.
