NOAA Chart Downloads

The National Oceanic and Atmospheric Administration now provides the public with free downloads of  U.S. nautical charts, covering coastal areas and the Great Lakes. NOAA charts are updated periodically and include Notice to Mariners corrections.

NOAA charts are available in several formats:

Raster Navigational Charts (RNC), Electronic Navigational Charts (ENC) require third party electronic charting software for use.

NOAA BookletCharts™ (Experimental) are another option for mariners. These low resolution charts are divided into page-sized, printable sections.
