ShippingExplorer is a cost-effective software to track vessels with live data. E-Mail and SMS Alerts. You draw a zone on the map and once the specified ship enters that zone you'll be alerted via e-mail or SMS on your cell phone. Track- and Port-History of a Ship. We record every step a ship makes so that you can later see when and where a ship was. Dozens of Filters. Filters help you to see only ships of a special kind on your map. Many more dynamic filters were included such as the "Destination"-filter ("Which vessels are going to Hamburg?"). These and many more filters can be found right next to the map. Port Traffic. You can see which ships came in and went out on a specific day.
