Numerous AIS tracking networks broadcast over the internet are available. Among the best known : Marine Traffic, Vessel Finder, SiiTech, LocateEverything, and many others.

But that was not the real problem. It was above all not to lose sight of the crew, because come back to its fall position "reckoning" was virtually mission impossible. And still today, with our sophisticated electronic means, It's not as easy as you might think… Read more …
