Perusing around the internet I found the following post, seems the only thing we need to know is the names of the vessels
Subject: How to Track Your 645 Across the Ocean....
... OK, this probably falls into the category of certifiably obsessive compulsive but for all of you out there crazed like me (no offense intended), meaning those who have a vehicle on the water on its way, here's some additional info on how to track it's progress:
First, get the name of the vessel your car is cruising on (you should be able to get this from your dealer), and go to the U.S. Coast Guard vessel search page linked below:
This page will tell you some interesting info about your ship (including it's most recent service problems and how old it is - GULP!), but will also give you an important piece of information called the Vessel Call Sign. This will be a short numeric or alpha designator for the vessel that is used to identify it for various marine purposes.
Next, go to a site from an organization called Ocean Weather Inc. at:
Click on the tab for "Current Marine Data" - then click on the map for the section of the world where you think the ship should be about now. You'll see data points marked with the Call Signs, and with any luck, you'll be able to locate the exact location of your vessel and vehicle!
This site is updated hourly, as ships report in their locations. It is possible that you'll see your ship one time and not another, depending on how and when it reports in. But, you'll eventually be able to track it coming across the pond if you're so inclined - assuming you are able to get the Call Sign.
The other place for information - although less current - is from the cargo company itself, and I believe this has been reported previously, but for newcomers, if your car is being shipped by the Wallenius Wilhelmsen lines, you can go to their website at:
Here you can track by vessel name, voyage number or VIN. If the VIN doesn't work, try the vessel name which is a bit more reliable.
Just thought there might be some of you who'd be interested....
