Navigation control
During pilotage, the ship's radars and other navigational aids must operate continuously, even if visibility is good, and the ship's position must be checked frequently.
To protect against malfunction, the instruments must be operated by the ship's master or officer of the watch, and not by the pilot.
The officer of the watch should keep a close watch on the navigation and check the position of the vessel, making charts at such frequent intervals as will immediately call attention to deviations from the intended course.
The position of the vessel should always be plotted on the chart at intervals of no more than ten minutes. It is important that fixation be achieved by more than one navigation method. Where a vessel is following a designated route, it is important that positioning be carried out using fixed lights whenever possible.
The officer of the watch must immediately call the master if he has any doubts about navigation or detects any deviation from the intended course.
Maneuvers (Prices for seaman's certificates)
On ships equipped with a Main Control for maneuvering, it is very important that this control is controlled by the captain or officer of the watch. If control is in the pilot's hands and communications are lost, it may be difficult for the captain to evaluate the pilot's maneuvers or take immediate action in the event of an emergency.
River/Channel Navigation
In the case of such sailing, the captain must ensure that the speed in turns and narrow passages is reduced accordingly. In areas with shallow water, all masters have to do with the squatting effect, and he must also determine which areas should be traversed in high water.
In cases where it is intended to determine the position using the contours of the river bank, it should be borne in mind that this may change depending on changes in water level.
