AIDS TO NAVIGATION

Learn to recognize the different buoys and day markers; they are the signposts of
the waterways. The United States Aids to Navigation System (USATONS) is the
primary marking system used on inland water, coastal waters and rivers. This
system is maintained by the USCG.
Navigational aids are designed and placed accordingly to help you navigate safely
on the water. Learn to recognize the different buoys and day markers.
The following information is based on the USATONS. For further information,
contact the USCG and state and local marine authorities. Also visit www.uscg.mil
for buoyage system information.
The USATONS uses buoys, beacons and minor lights as markers.
NEVER tie or anchor to a navigational aid. This action is unlawful and dangerous
to you, your boat and other boaters.
NEVER move or damage a navigational aid. This action is unlawful and
dangerous for other boaters.
Buoys
Most anchored floating markers are generally referred to as buoys. Buoys have
many uses and color schemes, and can vary in size and shape. The most
commonly used buoy colors are white, red, green, yellow and black. Buoys may
be unlighted or lighted. Some are audible; others have both an audible and a
visual signal. Lights, bells and horns on buoys aid in night boating or poor visibility
conditions. Buoys with unique light-flashing characteristics are identified on
nautical charts with the specific flashing pattern.
Become familiar with the specific buoys used in the waters where you are boating.
Contact local authorities for specific information and/or navigational aid charts for
your waterways.
