Abstract

A mathematical model is presented for predicting the resistance and trim angle of bare stepless planing hulls in calm water. Volume Froude numbers covered are 1 to 3.5 for resistance and 1 to 4 for trim angle. The predictive technique is established by regression analysis of data of systematic Series 62 (with deadrise angle of 12.5° and 25°) and Series 65. The mathematical model is a function of four hull form and loading parameters [loading coefficient (area coefficient), ratio of length to beam, longitudinal center of gravity location, deadrise angle] and section shape. The method presented makes it possible to estimate the resistance of planing hulls in the early stage of design and is suitable for programming.
