    These are some of the so-called 'directional derivatives' which are used to analyze ship maneuvering characteristics. The directional stability of a ship design is one of the areas which must be assessed by model tests or trials of full-size vessels.

    Some of the theory of ship maneuvering is explained in Principles of Naval Architecture, Vol. III (1988), which also presents a list of these quantities and their definitions.
