Abstract

In this paper, resistance results of three models, each representing a typi- cal hull form of a category, are examined with respect to their resistance, sinkage and trim characteristics. The three hull forms concerned are of the categories: displacement, semi-displacement or semi-planing, and fully- planing with transom sterns. Parameters varied and studied include the longitudinal position of the centre of gravity and the loading conditions over a range of speeds corresponding to the maximum operating volume Froude numbers of Fny ~ 1.75 for the displacement hull, Fny % 2.5 for the semi-planing hull and Fny % 3.9 for the fully-planing hull. Hull forms were developed and hydrostatics were calculated with the aid of a computer aided ship design package run at the Centre for
