Whistle Signals
Out on the water, whistle signals are commonly used. Although using
a whistle signal is not necessary every time a boat is nearby, operators
must signal their intentions when necessary to avoid potentially con-
fusing or hazardous situations. Use whistle blasts early enough to be
noticed and understood by other boaters.
It is customary for the privileged boat to signal first and the yielding
boat to return the same signal to acknowledge she understands and
will comply. Use the danger signal (five or more short and rapid blasts)
if intent is not clear. A short blast is 1 or 2 seconds long. A long blast is
4 to 6 seconds long. The Navigational Aids Chart at the end of this
chapter lists the meanings of the various whistle signals.
NAVIGATIONAL AIDS
Aids to navigation (ATONS) help you to travel safely on the water. They
help you get from one place to another and are most helpful if you
have a nautical chart. A navigational aids chart is at the end of this
chapter.
IMPORTANT: NEVER tie your vessel to an ATON. It is illegal because it
blocks the ATON from the view of other boaters. Decreased visibility
can contribute to a serious accident which may result in property dam-
age, personal injury, or death.
There are two ATON systems. The system used on federal waters is
known as the International Association of Lighthouse Authorities
System B (IALA-B). The Coast Guard maintains this system. The second
system is the Uniform State Waterway Marking System (USWMS). This
system is maintained by state authorities.
International Association of Lighthouse Authorities
System B (IALA-B)
IALA-B uses four types of ATONS. This chapter discusses the two most
common markers: lateral markers and safe water markers. Other feder-
al markers include special markers and isolated danger markers. The
Navigational Aids Chart at the end of this chapter shows these aids.
Lateral Markers
Lateral markers indicate the sides of navigable channels. They consist
of lighted can or nun buoys and daymarks. Each has a number and is
either red or green. The numbers on green markers are odd. Red mark-
ers have even numbers.
