In open water How far does an operating vessel stay away from a diver down flag?

In open water, vessels are generally required to stay at least 100 feet (approximately 30 meters) away from a diver down flag. This distance helps ensure the safety of divers by minimizing the risk of collisions. However, it's essential for boat operators to be aware of local regulations, as distances may vary by region. Always exercise caution and be vigilant when navigating in areas where divers are present.
