On the drop down menu on the left, click on "go to Gibraltar". You can also click on a boat and a pop up window shows you its name, flag, speed, heading, size, draft, destination, and a photo. If you click on "go to vessel-name", it even shows you where it's been. If you click on "go to port-name", it shows you who is there. It's a terrorists dream come true!
Right now, heading for Hell Gate at a speed of 5.6 knots and a heading of 35*, is the tug Pegasus. He's supposed to be heading in the other direction to get to Norfolk. I guess he's lost.
