Volume 1 of Basic Ship Theory presented fundamental work on ship shape, static behaviour, hazards, protection and ship strength. It described in detail the environment on which marine vehicles have to work and the properties of the sea and air. This volume discusses the dynamic behaviour of ships and other vechicles in the complex environment in which they operate. It examines how these surroundings can be controlled to the maximum comfort of vehicle and crew and looks at the creative activity of ship design. Familiarity with the first volume has beeen assumed throughout, but certain conversion factors, preferred values and symbols, and nomenclature are repeated.
