that other vessels see you. Most recreational vessels
are less than 30 feet in length and, according to “The
Rules of the Road”, shall be equipped with navigation
lights. These lights not only have a certain arc through
which they can be seen but must be seen from a mini-
mum distance. The following lighting requirements are
for recreational vessels less than 12 meters in length
(approximately 39.4”)
Light Arc Color Visible
Range
Masthead
Light 225 Wht 2
Starboard 112.5 Grn 1
Port
Sidelight 112.5 Red 1
Sternlight 135 Wht 2
The arc of the lights and color allows you to determine the
direction a vessel is moving. How good are your lights?
You should test them to see how visible you might be
at night. Whether on a trailer or at the marina, switch
on your lights and see how well they can be seen. Walk
away from the boat or row away, if you are at anchor or
at a mooring, and see how visible the lights are as you
move further away. How easy are they to see against the
background of lights on shore?
Does your stern light shine dead astern over the required
135 degree arc or does it shine to one side or up or down.
Can it be seen from the required 2 miles and why is that
important? As an example, let’s say that your stern light,
for some reason, can only be seen for ½ mile. You are
underway at 8 knots and a large ship is approaching at
15 knots. The ship is only 4 minutes away from collision
with you. By the time the ship “might” see you, identify
the light and decide on the reaction that should be taken,
it is too late. A ship traveling at 15 knots may take miles
to stop. Look at the stern light again, as you move from
the stern toward the bow. Does the stern light “disap-
pear” as the sidelight “appears”? The stern light should
disappear and sidelight appear at 22.5 degrees abaft the
beam. If you don’t see the green starboard sidelight or
the red port sidelight when the stern light disappears,
there is a problem with the arc of one or all of these lights.
This means that if another boat were approaching you at
the angle where no lights are seen, there is increase risk
of collision.
If both the sternlight and sidelights are seen brightly at the
same time, you still have a problem. A vessel approach-
ing won’t know whether they are overtaking or crossing
and whether they should give-way or stand-on.
You should also check to make sure that your masthead
light disappears at the same time each sidelight disap-
pears and they both disappear when the stern light
appears.
Check your sidelights from dead ahead. You should see
both red and green. However, by moving toward one
side by 1-3 degrees, you should then see only one light.
If you still see two lights, an approaching vessel won’t be
able to tell which direction you are going.
It is very important to be seen from a distance but also
for an approaching vessel to be able to determine your
direction of travel.
When boating at night, remember the following: “ When
two lights you see ahead, turn your helm and show your
red.”
4.5.4 Sound Signaling Device
Your boat is provided with a horn which conforms with
U.S. Coast Guard requirements for boats of this size. All
class A boats are recommended to carry a hand, mouth,
or whistle, as well as a power operated horn. The device
should be used to promote safe passing, as well as a
warning to other vessels in fog, or confined areas, or as
a signal to operators of locks or drawbridges. Following
are standard whistle signals:
One Prolonged Blast..........Warning Signal
One Short Blast..........Pass on my port side
Two Short Blasts..........Pass on my starboard side
Three Short Blasts..........Engines in Reverse
Five or More Blasts..........Danger Signal
