Mariners now have a new option to obtain information that is contained in the Local Notice to Mariners (LNM) for USCG District 13. Users can now use a map format to narrow down the specific area of interest, such as just the Columbia River, to reveal marine safety information.
To use this feature, zoom in the chart to choose an area of concern, in the upper right corner of the chart choose which layers you wish to display. Click “Data to Table” and then scroll to below the chart where you will see the categories available for display.
From this website, click “Sailing Links”, scroll down to “USCG LNM”, and then > “Marine Safety Info”.
