sector just above the horizon. Then, shift your gaze
upward about 10°, and search back to the starting point.
Repeat this process until the zenith is reached; then rest
your eyes for a few seconds before starting over.
When searching at night, keep your eyes moving.
Try to adhere to (stay with) the sector scan (and upward
shift) even though the horizon may not be visible. If you
spot a target (or even think you have), dont stare at it.
Instead, look slightly to either side.
Every object sighted should be reported, no matter
how insignificant it may seem to you. The initial report
consists of two basic partswhat you see and its bearing
(direction) from the ship. Aircraft sighting reports also
include altitude (position angle). Report the contact as
soon as you see it, then follow with an amplifying report.
Include the objects identity (destroyer, periscope, log,
and so on) and direction of travel (closing, crossing, and
so on). Refer to the ships SOP on reporting procedures.

In this chapter, you learned about the basic
fundamentals of the watch organization and some of the
procedures associated with standing a proper watch. We
also covered the importance of communications in
relation to watch-standing duties. Having well-trained
and competent watch standers would be useless without
