MOORING BUOYS
The only buoys you are permitted to
moor to are mooring buoys. Mooring
buoys are white with a blue
horizontal stripe. Mooring to a
navigation buoy, regulatory markers
or lateral markers is illegal.
DAYMARKS / DAYBOARDS
Daymarks or dayboards are
fixed visual markers in the
water. The markers are
commonly attached to a post
or piling and are sometimes
accompanied by a light.
Daymarks are either red or
green and are usually
triangular- or square-shaped, though their shapes can vary. Daymarks often display
numbers, which act as navigation guides. Red daymarks are usually triangular and
sometimes show an odd number. Green daymarks are usually square and
sometimes show an even number. The numbers on the markers are sequential and
increase from seaward.
LIGHTS AND LIGHTED STRUCTURES
Maneuvering a boat at night can be dangerous and confusing. To aid boaters with
navigation and to warn of hazards, the USCG and state and local authorities
maintain a variety of light structures. Some light structures are equipped with radio
beacons, radar reflectors and/or fog 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 and fairways.
