ShippingExplorer Ltd.

ShippingExplorer is a cost-effective software to track vessels with live data. It displays all vessels in range at their exact position on your favorite map. Additional information, photos, track history, etc. about vessels can be viewed right away in our client software.
The new version also allows you to use filters on the map (such as "All vessels heading to Rotterdam", "All cargo ships", "All German vessels" and much more).
Also a new Alert Zone system was introduced. 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.
