NOTICE
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.

and 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 side.
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 prop-
erty damage, personal injury, or death.
Returning from seaward is very clear if you have been
on the ocean. You are returning to port. By agree-
ment, going upstream on a navigational river is return-
ing 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 International Associa-
tion of LighthouseAuthorities System B (IALA-B). The
Coast Guard maintains this system. The second sys-
tem is the Uniform State Waterway Marking System
(USWMS). This system is maintained by state authori-
ties.
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 fair-
ways. 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 mark-
ers and safe water markers. Other federal markers
include special markers and isolated danger markers.
The Navigational Aids Chart at the end of this section
shows these aids.
Preferred Channel markers have horizontal red and
green bands. If lighted, the color of the light is the same
as the top of the band. They show the preferred chan-
nel 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 right.
B. Lateral Markers
Lateral markers indicate the sides of navigable chan-
nels. They consist of lighted can or nun buoys and
daymarks. Each has a number and is either red or
green. The numbers on the green markers are odd.
Red markers have even numbers.
Most lights on markers flash on and off. Others such
as lights on aids with no lateral significance are fixed.
