A craft that is operable on or above water and which has characteristics different from those of conventional displacement ships. A craft, which complies with either of the following characteristics would be considered a DSC:

A vessel which automatically maintains its position (fixed location or predetermine track) exclusively by the action of its thrusters.

The dynamical stability of a ship at any inclination is defined as the work done in heeling the vessel to that inclination.

A hydrodynamic system which controls or maintains the position and heading of the vessel by centralized manual control or by automatic response to the variations of the environmental conditions within the specified limits.

A seagoing vessel is subject to forces from wind, waves and currents as well as from forces generated by the propulsion system. Dynamic positioning is a capability of a vessel to maintain its position automatically using its propulsion system.

A load that produces significant acceleration of a body.
