Lateral Markers
Lateral markers are oriented from the perspective of being entered from seaward
(the boater is going toward the port). This means that red buoys are passed on the
starboard (right) side of the vessel when proceeding from open water into port, and
green buoys to the port (left) side.
The right side (starboard) of the channel is marked with RED, even-numbered buoys.
The left side (port) of the channel is marked with GREEN, odd-numbered buoys.
Day markers are colored and numbered the same as buoys. RED, triangular day
markers with even numbers mark the starboard side of the channel.
GREEN, square day markers with odd numbers mark the port side of the channel.
Fairways and mid-channels may be marked with safe water marks or buoys. These
marks indicate safe water all around. Safe water marks are red and white striped and
are round or have a red spherical topmark.
