This map shows boundaries of designated and identified marine transportation areas for commercial and recreational vessels in the region.

Data Considerations

Most of the features on the map are officially designated and actively maintained by the U.S. Coast Guard or the U.S. Navy, and their locations are well established. Examples include anchorages; maintained channels; safety, security, and regulated zones; danger zones and restricted areas; and boundaries of the Mandatory Ship Reporting System. Some of the pilot boarding areas on the map are not designated by federal or state government authorities. However, they are well known and considered important by the maritime commerce sector.


These data are final as referenced in the 2016 Northeast Ocean Plan. We will continue to work with relevant agencies and maritime stakeholders to ensure the data are maintained and updated.
