The U.S. Coast Guard is moving its national Coast Guard Marine Safety Information Bulletins (MSIB) library from this site to a new location under the U.S. Coast Guard Navigation Center (NAVCEN) Marine Safety Information site at https://navcen.uscg.gov/msib-national as part of its effort to provide faster and more intuitive access to critical maritime safety information and operational services.
Please see the announcement at https://navcen.uscg.gov/news-and-notices for more information on this topic.
This site will remain online and available for a limited time but will not be updated to reflect new MSIBs or changes to existing posts.
Users are encouraged to go to the new site from this time forward.
