Final answer:
Boaters operating in rivers, inlets, or navigation channels must stay a certain distance from a divers-down flag or buoy to ensure the safety of the divers.
Step-by-step explanation:
When boaters are operating in rivers, inlets, or navigation channels, they must make a reasonable effort to stay a certain distance from a divers-down flag or buoy. This is important for the safety of the divers who are underwater.
A divers-down flag or buoy is used to indicate that there are divers in the water. Boaters need to give them enough space to ensure that they are not at risk of being hit by the boat or its propeller.
A reasonable distance can vary depending on local regulations and conditions, but it is generally recommended to stay at least 100 feet away from the divers-down flag or buoy. This helps to prevent accidents and allows the divers to have a safe and undisturbed diving experience.
