Abstract:
This book presents a theoretical treatment, as well as a summary ofpractical methods of computation, of the forces and moments that acton marine craft. Its aim is to provide the tools necessary for theprediction or simulation of craft motions in calm water and inwaves. In addition to developing the required equations, the authorgives relations that permit at least approximate evaluation of thecoefficients so that useful results can be obtained. The approachbegins with the equations of motion for rigid bodies, relative tofixed- and moving-coordinate systems; then, the hydrodynamic forcesare examined, starting with hydrostatics and progressing to the forceson a moving vehicle in calm water and (after a review of water-wavetheory) in waves. Several detailed examples are presented, includingcalculations of hydrostatics, horizontal- and vertical-planedirectional stability, and wave-induced motions. Also included areunique discussions on various effects, such as fin?hullinteractions, numerical stability of integrators, heavy torpedoes, andthe dynamics of high-speed craft. The book is intended to be anintroductory-level graduate text and a reference for the practicingprofessional.
