Observation
It is the duty of an officer of the watch to ensure effective surveillance at all times.
Between sunset and sunrise, a watchman as well as a watch officer should be on the bridge. During daylight hours, if navigational circumstances permit, the officer of the watch may be assigned duties away from the bridge, at which time the officer of the watch should perform the duties of the watch officer, but at all such times the appointed watch officer should be readily available for call to the bridge if the officer in charge will require the services of a watchman.
On ships with a separate navigational room, the officer of the watch may visit the navigator's room when necessary for a short period of time to carry out the necessary navigational duties, but first ascertain that it is safe to do so.
