A 100-yard security zone is in place surrounding all cruise ships, tank
vessels, or any other vessel that the U.S. Coast Guard deems to be a
high interest vessel within San Francisco Bay, Monterey Bay and Humboldt
Bay. A security zone is in place around all U.S. Naval Vessels greater
than 100-feet in length within the navigable waters of the U.S. This
permanent protection zone extends 100-yards around all naval vessels and
it includes a 500-yard slow zone in which all mariners must operate at
the minimum speed necessary.
