A Local Notice to Mariners is a navigation publication in the United States issued by each U.S. Coast Guard District to disseminate important information affecting navigational safety within that District. This Notice reports changes and deficiencies in aids to navigation maintained by the Coast Guard. Other marine information such as new charts, channel depths, naval operations, and regattas is included. Since temporary information of short duration is not included in the weekly Notice to Mariners, the Local Notice to Mariners may be the only source of such information. Small craft using the Intracoastal Waterway and small harbors not normally used by oceangoing vessels need it to keep charts and publications up-to-date.
Since correcting information for U.S. charts in the Notice to Mariners is obtained from the Coast Guard Local Notices, it is normal to expect a lag of 1 or 2 weeks for the Notice to Mariners to publish a correction from this source.
The Local Notice to Mariners may be obtained free of charge by contacting the appropriate Coast Guard District Commander. Vessels operating in ports and waterways in several districts must obtain the Local Notice to Mariners from each district.
