1.0 General

1.1 DEFINITION OF GENERAL TERMS OF WIDE APPLICATION

Under this heading is listed a number of general terms frequently encountered in the field of naval architecture and marine engineering. To ensure that their general meanings are retained and that they are employed in the proper manner, their definitions are given here.

Axes co-ordinate

Generally a system of rectangular Cartesian co-ordinates and in particular:

  • Body axes (x, y, z)
    A right hand orthogonal system fixed in the body or ship. The x axis is forward and parallel to the reference or baseline used to define the body’s shape. In general the x axis is directed forward, y axis to port and z axis upward. NOTE This definition deviates from the ISO Definition. For dynamic considerations the origin should be at the centre of the gravity of the body and the z axis vertically downwards. The y axis is to starboard.
  • Fixed axes (x0, y0, z0)
    A right hand system nominally fixed in relation to the earth; the positive z0 axis is vertically downwards and the x0 axis lies in the direction of initial motion.

Control

As a noun, is applied to the act of controlling or directing, such as when controlling the movements of body or directing a ship in the steering, turning, and diving manoeuvres.

Control surface

The rudders, hydroplanes, and other hinged or movable device used for controlling the motions of body or ship.

Controllability

That quality of a body or ship which determines the effectiveness of movement of the controls in the producing any desired change, at a specified rate in the attitude or position of the moving body or ship.

Controls

The means or system provided to enable the crew of a ship to control its speed, power, attitude, direction of motion, and the like.
