rules as well as the boat operator. If you are new to water
skiing, seek certified training before starting. You will find it
especially helpful to join a local ski club, USA Waterski, or
similar organization when possible.
Always remember that the majority of water skiing injuries
are the result of impacts with other objects, so always look
whereyou are going and be aware of what is going on around
you.

Basic Boating Rules
You should be awareofthese rules and follow them whenever
you encounter another vessel on the water.
The rules presented in this manual are condensed and have
been provided as a convenience only. Consult your local
U.S. Coast GuardAuxiliary (USCGA) or Department of Motor
Vehicles (DMV) for a complete set of rules governing the
waters in which you will be using your boat. If you plan to
travel—even for a short trip—you would be well served to
contact the regional USCGA or DMV in the area where you
will be boating.
Review and understand all local and state laws.
Any time two vessels on the water meet one another, one
vessel has the right-of-way. It is called the stand-on vessel.
The vessel which does NOT have the right-of-way is called
the give-way or burdened vessel.
Theserulesdeterminewhichvesselhastheright-of-way,and
accordingly, what each vessel should do.
The vessel with the right-of-way has the duty to continue its
course and speed, except to avoid an immediate collision.
Whenyou maintainyour direction and speed, theothervessel
will be able to determine how best to avoid you.
The vessel which does not have the right-of-way has the duty
to take positive and timely action to stay out of the way of the
stand-on vessel. Normally, the give-way vessel should not
cross in front of the stand-on vessel. Slow down or change
directionsbriefly andpassbehind the othervessel. Youshould
always move in such a way that the stand-on operator can
see what you are doing.
This rule is called Rule 2 in the International Rules and says,
“In obeying and construing these rules due regard shall be
had to all dangers of navigation and collision, and to any
special circumstances, which may render a departure from
the above rules necessary in order to avoid immediate
danger.”
Encountering Other Vessels
There are three main situations in which you may encounter
other vessels and you must observe the Steering Rules in
order to avoid a collision. These are:
-Meeting (you are approaching another vessel head-on)
-Crossing (youaretraveling across the other vessel’s path)
-Overtaking (you are passing or being passed by another
vessel)
Using the following illustration in which you are the boat in
the center, you should give right-of-way to all vessels shown
inthe whitearea. In this instance,youare the give-wayvessel.
All vessels in the shaded area must yield to you as you are
the stand-on vessel. Both you and the meeting vessel must
alter course to avoid each other.
If you are meeting another power vessel head-on, and you
are close enough to run the risk of collision, neither of you
has the right-of-way. Both of you should alter course to avoid
an accident. You should keep the other vessel on your port
(left) side. This rule doesn’t apply if both of you can clear
each other by continuing your set course and speed.
Section III
Boating Rules

10 © 2002 Skier’s Choice, Inc.
When two power-driven vessels are crossing each other’s
path close enough to run the risk of collision, the vessel
that views the crossing vessel to the starboard (right) side
must give-way.
If the other vessel is to the port (left) side, maintain your
course and direction, provided the other vessel gives you
the right-of-way as it should.
If you are passing another vessel, you are the give-way
vessel. This means that the other vessel is expected to
maintain its course and speed. You must stay out of its
way as you clear it, altering course and speed as
necessary.
Conversely, if you are being passed by another vessel, you
should maintain your speed and direction so that the other
vessel can steer itself around you.
There are three other rules to always remember when
driving your boat around other vessels.
When navigating in narrow channels, you should keep to
the right when it is safe and practical to do so. If the
operator of a power-driven vessel is preparing to go around
a bend that may obstruct the view of other water vessels,
the operator should sound a prolonged blast on the whistle
or horn—four to six seconds.
If another vessel is around the bend, it too should sound
the whistle or horn. Even if no reply is heard, however, the
vessel should still proceed around the bend with caution.
If you navigate these type of waters, you should carry a
portable air horn, which are available from local marine
supply stores.
All vessels which are fishing with nets, lines or trawls are
considered under International Rules to be fishing vessels.
Boats with trolling lines are not considered fishing vessels.
Fishing vessels have the right-of-way, regardless of
position. These vessels, however, cannot impede the
passage of other vessels in narrow channels.
Sailing vessels should normally be given the right-of-way.
The exceptions to this are:
- When the sailing vessel is overtaking the power-driven
vessel, the power-driven vessel has the right-of-way.
- Sailing vessels should keep clear of any fishing vessel.
- In a narrow channel, a sailing vessel should not
hamper the safe passage of a power-driven vessel
which can navigate only in such a channel.
The waters of the United States are marked for safe
navigation by the lateral system of buoyage. The markers
and buoys you will encounter have an arrangement of
shapes, colors, numbers and lights to show which side of
the buoy a boater should pass when navigating in a
particular direction.
The markings on these buoys are oriented from the
perspective of being entered from seaward while the boater
is going towards the port. This means that red buoys are
passed on the starboard (right) side when proceeding from
open water into port, and black buoys are to port (left) side.
When navigating out of port, your position to the buoys
should be reversed: red buoys to port and black buoys to
starboard.
Many boating bodies of water are entirely within the
boundaries of a single state. The Uniform State Waterway
Marking Systems has been devised for these waters. This
system uses buoys and signs with distinctive shapes and
colors to show regulatory or advisory information.
These markers are white with black letters and orange
borders. The information signifies speed zones, restricted
areas, danger areas and general information.
Remember: Markings may vary by geographic location.
Always consult local boating authorities before driving your
boat in unfamiliar waters.
(See examples of buoys and markers next page.)
