FWMS System
The FWMS Lateral System is for use on navigable waters except Western Rivers
and Intracoastal Waterways. The markings on these buoys 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 (port) side of the channel is marked with GREEN, odd numbered buoys.
The middle of the channel is marked with RED and WHITE vertically striped
buoys; pass close to these buoys.
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 ashing characteristics are identied on nautical charts with the specic ashing
pattern.

Types of Buoys
There are several types and shapes of buoys. Buoys may be unlighted, lighted, with sound or
may have both an audible and a visual signal. Lights, bells and horns are used on buoys for night
or poor visibility conditions. Dierent shapes of buoys are shown below. Buoys with unique light
ashing characteristics are identied on nautical charts with the specic ashing pattern.
Mooring Buoys
The only buoys from which you are permitted to moor are mooring buoys. Mooring buoys are
white with a blue horizontal stripe. Mooring to a navigation buoy, regulatory markers or lateral
markers is illegal.
