ABSTRACT
ABSTRACT: Hydrodynamics of high-speed vessels supported by submerged hulls, hydrofoils, air cushion or a combination of these effects are considered. Resistance, propulsion, maneuvering and seakeeping are covered in the presentation. A water jet system in calm water and in a seaway is discussed. Special physical features of high-speed vessels are emphasized. Examples are the cobblestone oscillations of an SES in small sea states, cavitation, ventilation, dynamic instabilities and generation of waves (wash). The importance of nonlinear free surface effects in particular for planing vessels is pointed out. Both local and global slamming effects are discussed from a structural point of view.
