A blue and white flag, where the left half is white and the right half is blue, indicates what?

The blue and white flag, where the left half is white and the right half is blue, is recognized as a marker that indicates a 100-foot safe zone. This flag serves as an important visual cue for boaters, helping them understand areas where they should maintain a safe distance, usually around swimmers or other activities taking place in the water. Recognizing such flags is essential for ensuring the safety of both the boaters and individuals engaging in water sports or swimming in proximity.
