SECURITY ZONE 
The Coast Guard is establishing permanent moving and fixed security zones extending 100 yards in the U.S. 
navigable waters around and under all cruise ships, tankers, and High Interest Vessels (HIVs) that enter, 
are moored or anchored in, or depart from the designated waters of San Francisco Bay, Monterey Bay or Humboldt 
Bay, California. These security zones are needed for national security reasons to protect the public
and ports of Monterey Bay and Humboldt Bay from potential subversive acts. Entry into these security zones is 
prohibited, unless specifically authorized by the Captain of the Port San Francisco Bay, or his designated 
representative. Persons desiring to transit the area of the security zone may contact the Captain of the Port 
or his designated representative at telephone number 416-399-3547 or on VHF-FM channel 16 (156.8 MHz) to seek 
permission to transit the area. If permission is granted, all persons and vessels must comply with the instructions.
