A Systematic Study of the Rough-Water Performance of Planing Boats. Irregular Waves - Part 2

Abstract

A systematic study of the effects of deadrise, trim, loading, speed, lengthbeam ratio, bow section shape and sea state was made on the performance of a series of prismatic planing boat models operating in irregular waves. Measurements of the added resistance, heave and pitch motions, and impact accelerations at the bow and center of gravity served as the basis for evaluation. Statistical analysis of the results enabled direct comparisons between the independently varied parameters; and show in a quantitative way, the importance of these parameters on the rough-water performance of planing hulls. A design procedure was developed which predicts the performance of any given hull.
