Safety information
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
with respect to the buoys should be reversed;
red buoys should be to port and black buoys
to starboard.
Many bodies of water used by boaters are
entirely within the boundaries of a particular
state. The Uniform State Waterway Marking
System has been devised for these waters.
This system uses buoys and signs with dis-
tinctive shapes and colors to show regulatory
or advisory information. These markers are
white with black letters and orange boarders.
They signify speed zones, restricted areas,
danger areas, and general information.
Remember, markings may vary by geograph-
ic location. Always consult local boating au-
thorities before driving your boat in unfamiliar
waters.
