long blast is four (4) to six (6) seconds long. The Navi-
gational Aids Chart at the end of this section lists the
meanings of the various whistle signals.
Buoys are anchored floating objects and may
not always be in exactly the same position.
Daymarks are red or green boards with numbers. They
are on posts or groups of pilings tied together and called
dolphins. Daymarks and their supports are daybeacons.
Daybeacons may or may not have lights. If a red or

have odd numbers.
Red, Right, Returning is a basic rule to assist you in
using lateral markers. When you are returning from
seaward , keep red markers on the starboard (right) side
when you pass them. Keep green markers to the port
NEVER tie your vessel to anATON. It is illegal
because it blocks the ATON from view of other
boaters. Decreased visibility can contribute to
a serious accident which may result in property
damage, personal injury, or death.
Returning from seaward is very clear if you have been on
the ocean. You are returning to port. By agreement,
going upstream on a navigational river is returning from
seaward. The outlet ends of the Great Lakes are also
the seaward ends. Traveling from a large body of water
to a smaller one is considered returning from seaward.
There are two ATON systems. The system used on
federal waters is known as the InternationalAssociation
of LighthouseAuthorities 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.
C. Safe Water Markers
A. International Association of Lighthouse
Authorities System B (IALA-B)
Safe water markers have vertical red and white stripes
and mark the center of navigable channels and fairways.
Safe water markers included both lighted and unlighted
buoys and daymarks. If a marker is lighted, the light is
white and flashes the letter “A” is Morse Code.
IALA-B uses four types of ATONS. This section dis-
cusses the two most common markers: lateral markers
and safe water markers. Other federal markers include
special markers and isolated danger markers. The Navi-
gational Aids Chart at the end of this section shows
bands. If lighted, the color of the light is the same as
the top of the band. They show the preferred channel for
you to use at a junction point. Be sure to notice the
color of the top of the band, and treat it as any other
marker you would of that color. If the band is red and
you are returning from seaward, keep the marker to the
B. Lateral Markers
Lateral markers indicate the sides of navigable chan-
nels. They consist of lighted can or nun buoys and
The numbers on the green markers are odd. Red mark-
ers have even numbers.
Most lights on markers flash on and off. Others such as
lights on aids with no lateral significance are fixed. They
stay on all night. ATON lights flash in regular patterns.
