Abstract : Smooth-water resistance and trimming characteristics are presented for 22 planing craft hulls representing systematic variations of chine planform, length-beam ratio, and deadrise angle. Resistance-weight ratios and trim angles have been derived from model experimental data at comparable speed and loading conditions as a function of the location of the longitudinal center of gravity in order to facilitate optimization in small craft design.
