Zooming By Ship (Ship MMSI Number)

Note: This zoom type may not be available on your ERMA site and is based on user privileges.

  1. If your permissions give you access to the NAIS (Nationwide Automatic Information System) feed, enter the known ship's 9-digit MMSI number or at least four characters of the ship name.
  2. Click Find It! A black X appears on the map showing the most recent received location of the ship. Depending on how often a ship's transponder reports information, this location may be accurate to within the minute or it could be several hours old.

  3. Under Paper Size, select the size of the paper you will print the map on, and the orientation of the map image on the paper.
  4. In your web browser, open the print settings and make sure that the paper size and orientation match what you have selected on ERMA's Print tab.
