bearing cannot be followed safely. This information is
available on the navigation chart being used.
Most lighthouses and LANBYS are equipped with
fog-signaling apparatus, ordinarily sounded
automatically by mechanical and electrical means. For
identification purposes, each station has its own
assigned number of blasts, recurring at specified
intervals. A definite time is required for each station to
sound its entire series of blasts; this timing provides
another means of identification.
The various types of apparatus produce
corresponding variance of pitch and tone, thus giving
your ear a chance to compare the sound of a station with
its description in the Light Lists, published by the U.S.
Coast Guard. A thorough knowledge of the lights and
buoyage system is important because you will be, at one
time or another, assigned to lookout duties as a bridge
watchstander, or as a boat crew where knowledge of the
buoy system is used extensively.
The knowledge and experience you acquire as a
Seaman today will help you to do whatever job you are
assigned to the utmost of your ability in the future.
As a Seaman you may he assigned to any of the
numerous vessels of the U.S. fleet. Aboard most ships,
your job will most likely be different from the job you
left. With hands-on training indoctrination, you
should be performing your assigned duties as well as
any other Seaman.
This chapter has covered many knowledge factors
relating to boat handling, including a basic knowledge
of the Rules of the Road and the buoy system. You can
be assured that your time at sea will be challenging and
