The internationally recognized flag to signify that there is a diver below is known as the Alpha or Alfa flag, which is white and blue and has the following appearance: a white flag with a blue swallowtail. However, in North America, particularly in the United States, the most common flag to indicate a diver in the water is the dive flag, which has a red background with a white stripe from the top left corner to the bottom right corner. It is crucial for boats to recognize and avoid these flags for the safety of the divers. Therefore, when you see a flag indicating the presence of divers, it is essential to stay clear of the area to prevent any accidents or interference with their activity.
