Piloting
Introduction
Navigation becomes more demanding when your ship is near land or in
restricted waters where there is an immediate danger of possible
grounding. Piloting is the process of safely directing the movement of a
vessel from one point to another involving frequent or continuous
determination of a ship’s position relative to geographical points, to a
high order of accuracy.
