In many cases, efficient handling of such incidents is significantly increased by having access to a prediction of the associated drift path. Shipping companies need to be able to determine the drift paths of floating assets, objects or spilled chemicals at an early stage after an incident so these can be plotted on their own navigational charts to plan a prompt and efficient response when time is of the essence.

The direction and the motion shown by GPS at that moment are the set and drift the current. ship is considered stopped when she is stopped w.r.t water in which she is floating. ![]() Thus a student might Wonder as to ‘why GPS is still showing, say ‘2 knot speed the while Water alongside may appear to be still with respect to the ship. During an ‘Inertia or simple stop’ manoeuvre carried out in open sea it may be necessary to take into account the currents, if any, as the current might continue to carry the ship. A time speed graph may be prepared for ‘stop manoeuvre. A navigator makes the best use of this facility. Nowadays the precise course & speed over ground may be read directly on a GPS receiver. It may be provided for loaded & light conditions. Stopping distance details may be provided for sea speed, harbour speed, half speed etc. Stopping distance is the distance, which, a ship will continue to move after action is taken to stop engines and till the ship comes to rest.
