A CHUMMING FLAG informs others that a boat is actively chumming/baiting with cut bait, live bait or ground bait to lure fish (shark) to the boat. A chumming flag is recommended when targeting sharks to indicate that caution should be used when entering the water. The colors yellow/blue were chosen as it is the same as the Nautical Flag steer clear. The pictographic design is internationally easy to understand. With a diagonal pattern it is easy to see at a distance.
