the.water..They.help.you.get.from.one.place.to.another.
and.are.most.helpful.if.you.have.a.nautical.chart..A.

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 an ATON. It is illegal
because it blocks the ATON from view of other
boaters. Decreased visiblility can contribute to
a serious accident which may result in property
damage, personal injury, or death.

been.on.the.ocean..You.are.returning.to.port..By.
agreement,.going.upstream.on.a.navigational.river.is.

There.are.two.ATON.systems..The.system.used.on.
federal.waters.is.known.as.the.International.Associa-
tion.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.
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.
discusses.the.two.most.common.markers:.lateral.
markers.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.pre-
ferred.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.sea-
ward,.keep.the.marker.to.the.right.
B. 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.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.
They stay on all night. ATON lights flash in regular
patterns. For example, they may flash every three
seconds, or in groups such as two flashes and a
pause. There are a number of flashing patterns,
which.help.you.identify.the.light.at.night..To.identify.
Buoys are red or green floating ATONS. If lighted, they
have.either.red.or.green.lights..Unlighted.green.buoys,.
called.cans,.look.like.cylinders..Unlighted.red.nun.
buoys.have.a.cone.shaped.top.with.their.points..
