A buoy is used to mark the location of fishing gear and typically includes a pole, a float, a weight, a light reflector, and one or two flags. Some buoys also have a beacon or a radar reflector for better visibility. A lanyard is attached to the buoy, allowing it to be securely connected to the rest of the fishing gear.

The buoyline is the line that connects the groundline to a buoy. It plays an important role in longline fishing by marking the position of the gear, keeping the line at the right depth, and preventing it from drifting out of place.
