The first part of the study presents a simple method, based on the known results of airfoil theory, of estimating the hydrodynamic characteristics of high speed planing craft. Comparisons between present calculations and experiments for flat and prismatic surfaces in steady triming, rolling and yawing attitudes are made. The calculations seem generally to be in good agreement with the data. The second part of the report discusses the turning and stability of planing craft. The governing equations, based on the kinematics and dynamics of rigid bodies are in many respects similar to that given for hydrofoil boats. Once the hydrodynamic characteristics are known the stability and turning performance of craft can be assessed with the aid of these equations. (Author).
