peacetime. When the required number of people is
available in peacetime—and always in wartime—three
basic types of lookout watches are established. They
are (1) surface lookouts who search from the ship to
the horizon, (2) low-sky lookouts who search from the
horizon to 5° above it, and (3) high-sky lookouts who
search from the horizon to the zenith (directly
overhead). Additionally, several people may be
assigned to each search, each person being responsible
for a specified sector. Adjacent sectors have about a
10° overlap, so no area will go unsearched.
The normal peacetime lookout organization has
three people in each watch section. Two persons are
located on the bridge or atop the pilothouse; one
searches to port, the other to starboard. Their sectors
extend from just abaft the beam forward to dead
ahead. The third person is stationed aft and is called
the after lookout or life-buoy watch and is responsible
for the sector extending from the starboard beam aft
and around to the port beam (figure 1). In addition
