Obstructions, channel junctions, etc. are marked with RED and GREEN horizontally
striped buoys.
A RED band at the top means the preferred channel is to the left of the buoy; a GREEN
top band means the preferred channel is to the right of the buoy.
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.
Lights, bells and horns are used on buoys for night or poor visibility conditions. Buoys
with unique light flashing characteristics are identified on nautical charts with the specific
flashing pattern.
