*Under the guidance of NOAA's Office of Coast Survey, this chart has amassed enough critical and non-critical corrections such that OceanGrafix has issued a new edition number. This edition number now overrides the NOAA edition number. This chart contains all of the latest NOAA updates at the time of printing and is available for purchase online or from one of our retailers.

This chart has been canceled so it is NOT updated weekly and does NOT include all of the latest Notice to Mariners corrections. This chart is available for purchase online.
