Dynamic Equilibrium Evaluation for Planing Hulls with Arbitrary Geometry and Variable Deadrise Angles – The Virtual Prismatic Hulls Method

This paper describes the development of a semi-empirical computational method to solve the dynamic equilibrium problem for planing hulls with arbitrary geometry, including variable deadrise angles along the length. The method is based on Savitsky's method (1964) and it is named ‘Virtual Prismatic Hulls Method’, allowing for the determination of the intensity of the lift force and the resulting center of pressure, in order to determine the dynamic equilibrium position and the drag force, at the fully developed planing regime, for any arbitrary, non-prismatic hard chine hull form. Results produced by the method are presented and investigated and their applicability is established and compared with experimental results of well-known systematic series of planing boats.
