Abstract

This study investigates dynamic instabilities during turning maneuvers of a high-speed planing hull using computational simulations, including turning circles, quick turn, and avoidance line tests. A Generic Prismatic Planing Hull (GPPH) model is used for the simulations. Relevant performance criteria and dynamic instabilities reported in the literature are summarized and applied to assess the turning maneuvers of the GPPH. Turning circles are analyzed based on circular motion equations and force and moment balances. Instabilities are identified through animation analysis and time histories of motion and acceleration quantities. The maneuvering boat speed is determined in the quick-turn tests, while the performance in the avoidance line test is evaluated under various settings.
