Costs to Establish a Database on Icebreaking Operations in the Great Lakes

The Coast Guard met the requirement of the Coast Guard Authorization Act of 2022, to establish and maintain a database for collecting, archiving, and disseminating data regarding icebreaking operations in the Great Lakes by using enterprise information technology (IT) already in use by the Coast Guard. The Coast Guard and Industry Representatives agreed upon a plan for the Coast Guard to collect data regarding shipping delays caused by inadequate icebreaking resources utilizing existing communications (i.e., icebreaking planning calls, icebreaking assistance requests, vessel movement reports) and will be posted weekly to the Coast Guard Navigation Center website. The Memorandum for Public Distribution can be viewed here.

Coast Guard Cyber Command releases 2024 CTIME report

U.S. Coast Guard Cyber Command released its fourth annual Cyber Trends and Insights in the Marine Environment (CTIME) report. The U.S. Coast Guard continues its commitment to securing critical systems in the Marine Transportation System (MTS) by collaborating with the maritime industry to share best practices and provide insights into evolving cyber risks. In the modern MTS, the interconnectedness of operational technology and information technology increases the risk of cyber attacks. CTIME expands on these recent findings derived from engagements with MTS partners throughout 2024, conducted by Coast Guard Cyber Protection Teams (CPTs) and the Maritime Cyber Readiness Branch. 

“The adoption of new technologies continues to drive operational efficiencies while also creating new vulnerabilities and attack vectors. CGCYBER is committed to partnering with industry to address this evolving threat landscape and protect the Marine Transportation System in cyberspace," said Rear Admiral Jason Tama, Commander, U.S. Coast Guard Cyber Command.

Four key takeaways from the report include: 

• Supply chain risks and other observed vulnerabilities exist within ship-to-shore cranes manufactured in China. 

• Improved connectivity and the proliferation of networked technology create new cyber risks for vessels. 

• There was an uptick in cyber incidents and CPT missions involving cloud systems and services. 

• Similar cybersecurity vulnerabilities were observed in previous CTIME reports, however the baseline cybersecurity posture has been improved across the Marine Transportation System. 

The full report contains insights and recommendations valuable for all Coast Guard units and organizations ranging from large, cyber-mature organizations to small businesses looking to build out their own cybersecurity programs.

Alert: The Coast Guard has retired Homeport

The Coast Guard retired Homeport as of April 12, 2025. Moving forward, you will need to use alternate approaches for tasks typically performed through the Homeport platform. 

To protect the nation’s Maritime Transportation System, we are transferring Homeport functionality to more secure information systems. The Homeport system is facing increasing costs and system obsolescence. As a result, it is no longer a viable tool for managing the many functions required to ensure the smooth and safe flow of vessel traffic.  

“We recognize that Homeport has been a trusted tool for mariners and the broader maritime community,” said Rear Adm. Wayne Arguin, Assistant Commandant for Prevention Policy. “We are committed to keeping these users informed and providing alternatives to the functions and information Homeport provided as we transition.”  

The Coast Guard is establishing temporary workarounds to ensure essential services remain accessible until we can identify the best permanent approach for each function.  

The new Homeport Solutions & News website will be our primary tool for keeping you informed as new tools come online.  

You can also visit Maritime Commons, the Coast Guard’s blog for maritime professionals, and subscribe for the Maritime Commons RSS feed to receive regular e-mail updates. 

We realize that decommissioning Homeport is a significant change, and we are committed to making the transition as easy for you as possible. On behalf of the U.S. Coast Guard, thank you for your important role in building a thriving U.S. economy and your commitment to safe, secure maritime commerce. 

NAVCEN's upgraded Local Notice to Mariners & Light List application

The U.S. Coast Guard Navigation Center (NAVCEN) has launched its updated Local Notice to Mariners (LNM) and Light List application, reaffirming our commitment to enhancing access to critical maritime safety information.

This upgraded application now allows users to download and print LNMs for entire Coast Guard Districts or define their own area of interest using the GIS tools to zoom in and access localized data.  The form section enables users to organize and sort LNMs by waterway or category. For programmatic integration, GeoJSON files are available to download for data ingestion into other applications.

We sincerely appreciate your patience and are confident this enhanced version will better serve the diverse needs of the maritime community.
