The Coast Guard can now block ships from a 500-yard radius around certain cargo vessels

The Coast Guard is creating a temporary moving security zone in the Corpus Christi Ship Channel. This zone will extend 500 yards around vessels carrying high-security cargo, and no other vessels or people can enter without permission.

This rule gives the Coast Guard immediate power to clear a wide area around specific ships. It means that commercial and recreational traffic in a major shipping channel can be stopped or rerouted on short notice. This kind of localized, temporary restriction is a tool for managing specific, high-risk transits without permanent changes to navigation rules.
