Lights, buoys and radio aids

Off station / missing buoy

A buoy that is not in its charted position — dragged, damaged, missing or removed.

Buoys mark channels, dangers and turning points, and a buoy in the wrong place is worse than none. Storms drag them, ships hit them, and ice carries them away. "OFF STATION" means the buoy is not where the chart shows; "MISSING" or "DESTROYED" means it is gone.

Temporary replacements are often a different type of buoy or show a different light; the warning then gives the substitute's characteristic.
