Isolated Danger Markers
Isolated danger markers indicate an isolated
danger which may be passed on all sides. These
markers are colored black with one or more broad
horizontal red bands and are equipped with a
topmark of two black spheres, one above the other.
Isolated Danger
(No Numbers–May be
Lettered)
On inland waters, a buoy with alternating vertical
black and white stripes may be used to indicate that
an obstruction or other danger exists between the
buoy and the nearest shore. DO NOT pass
between the buoy and the shore.

Light Structures
Maneuvering a boat at night can be dangerous and
confusing. To aid boaters with navigation and warn
of hazards, the USCG and the state and local
authorities maintain a variety of light structures.
Some light structures may be equipped with radio
beacons, radar reflectors and/or signals.
Minor Lights
Minor lights are colored according to the buoyage
marking system in use. They are similar to lighted
buoys, except they are usually higher and on more
stable platforms to increase visibility. Most minor
lights are part of a series to mark a channel, river or
harbor.
