Abstract
The Coast Guard announces the availability of Revision 9 to Maritime Security (MARSEC) Directive 104-6, which provides guidelines for U.S. vessels operating in high-risk waters (HRW) where acts of terrorism, piracy, and armed robbery against ships are prevalent. The directive contains security-sensitive information and, therefore, cannot be made available to the general public. U.S. vessel owners and operators who have needed to take action under previous versions of MARSEC Directive 104-6, should immediately contact their local Coast Guard Captain of the Port or District Commander for a copy of Revision 9. This revision contains important updates to HRW locations and organizational responsibilities regarding addressing security risks in those waters.

directive contains security-sensitive information and, therefore,
cannot be made available to the general public. U.S. vessel owners and
operators who have needed to take action under previous versions of
MARSEC Directive 104-6, should immediately contact their local Coast
Guard Captain of the Port or District Commander for a copy of Revision

organizational responsibilities regarding addressing security risks in
those waters.

SUPPLEMENTARY INFORMATION: Maritime Security (MARSEC) Directive 104-6
Revision 9 replaces Revision 8, previously signed on August 11, 2021.
The directive provides direction to U.S. flagged vessels operating in
High Risk Waters (HRW) where acts of terrorism, piracy, and armed
robbery against ships are prevalent. This revision reflects the
addition of provisions for the reduction of electronic vessel
transmissions, an amendment to the applicability of Annex 1 to include
the high risk waters of the Red Sea and Arabian Sea, and a revision to
the northern limits of the high risk waters of the Red Sea.
Electronic vessel transmissions broadly include any device onboard
capable of generating a radio frequency signal with or without operator
intervention. Examples of electronic vessel transmissions include those
from cellular and satellite phone systems, vessel-to-vessel and vessel-
to-shore radio transmission equipment, Automatic Identification System,
Long Range Identification and Tracking Systems, and radar.
U.S. vessel owners and operators who have needed to take action
under previous versions of MARSEC Directive 104-6 should immediately
contact their local Coast Guard Captain of the Port or District
Commander for a copy of Revision 9, which contains important updates to
the locations of HRW and to the guidelines for addressing security
risks in those waters. The Coast Guard advises owners and operators
that, under Revision 9, they may need to take specific actions in
accordance with MARSEC Directive 104-6 before their vessel enters HRW.
This notice is issued under authority of 33 CFR 101.405(a)(2) and 5
U.S.C. 552(a).
Dated: January 31, 2025.
A.M. Beach,
Captain, U.S. Coast Guard, Director of Inspections and Compliance.
