Day Beacons are signs posted on land or water. They are without lights and are intended for daytime use only. These beacons use the same colours as the Lateral System and are typically used as channel or hazard markers. They may be marked with reflective lettering for identification on marine charts.

Port-Hand Day Beacon

These beacons consist of a black and green square on a white background framed by a reflective green border. A Port-Hand Day Beacon identifies the port (left) side of a channel or hazard and must be kept on the left side when proceeding upstream. Port-Hand Day Beacons may display an odd number marked with reflective white lettering for reference on marine charts.

Port-Junction Day Beacon

These mark the junction of two channels and may be passed on either side. If the preferred channel is desired, they should be kept on the vessel’s port (left) side when traveling upstream.

Starboard-Hand Day Beacon

These beacons consists of a red triangle on a white background framed by a reflective red border. A Starboard-Hand Day Beacon identifies the starboard (right) side of the channel or hazard and must be kept on the right side when proceeding upstream. They may display an even number marked with reflective white lettering for reference on marine charts.

Starboard-Junction Day Beacon

These beacons mark the junction of two channels and may be passed on either side. If the preferred channel is desired, the Starboard-Junction Day Beacon should be kept on the vessel’s starboard (right) side when travelling upstream.
