Some three weeks ago JMM asked on locating data on US shipping affected by piracy and Entropy offered some pointers. Courtesy of a story on a cruise ship disabled in the Baltic:http://www.telegraph.co.uk/news/worl...r-failure.html I found a ship tracking website:http://www.vesseltracker.com/en/static/Company.html and home page:http://www.vesseltracker.com/app

For a relatively small subscription you can track vessels.

I was not aware that the internationally mandated Automatic Identification System (AIS) means all vessels over 300 tonnes report location plus, for more see:http://www.vesseltracker.com/en/stat...html#wasistais

Admittedly some ship captains turn their AIS off at times (from a Swedish observer).
