What is the maximum distance a license or permit may be kept from the shore while diving?

The maximum distance a license or permit may be kept from the shore while diving is established as 500 yards. This regulation is primarily in place to ensure that divers remain within a relatively safe and manageable distance from the shore, allowing for easier access to emergency assistance if needed. It also helps in maintaining the organization and monitoring of activities occurring near the shoreline, especially as it pertains to recreational and commercial diving activities.

Establishing this distance supports compliance with safety standards and enables the management of aquatic resources by keeping divers within regulated zones. The other distances presented exceed 500 yards, which may create complications in safety oversight and resource management, hence they are not appropriate as maximum distances for keeping permits or licenses while diving.
