AIS is the only way you can track it. The ship also reports its position back to its company via sat phone, but I doubt that the shipping company would share that with you. As soon as the ship is close enough to land that there is an unbroken chain of stations (vessels) all within about 20 miles of one another, then the ship will again appear on the website, so just keep monitoring it. You can do a dead reckoning at about 15 nautical miles per hour and knowing the planned route, you can estimate when the vessel will be back in AIS range.

I have been spoiled by the reports and tracing while the Marina Ace was in European waters.
Assuming that she takes the great circle route (which she seemed to be following before she 'vanished'), she will probably take a track that takes her along the northern coast of Canada. Depending on the traffic there, I guess that there is a hope of reacquiring her in a few days.
Working backwards, I know that the Marina Ace is due in Davisville, RI on the 29th. She will have to be in the traffic coming out of the St. Lawrence (and the Great Lakes) a couple of days before that. That brings up the question of whether there actually is any traffic on the St. Lawrence. Is it open yet? Still, the farther south the vessel proceeds, the more likely that her signals will be received and relayed.
I guess, that like the Apollo capsules behind the moon, I can only wait and hope for a reacquisition of signal. Unlike Capcom, I don't have the benefit of knowing precisely when that is expected.

Marina Ace is due in Davisville in Narragansett Sound (RI) tomorrow. That means that by now she should be south of Portland, ME on a course that should take her past Boston and Cape Cod (possibly through the Cape Cod Canal) very soon. These are heavily trafficked waters with lots of navigational aids.
In law school I learned about something called the presumption of regularity. It basically says that one should assume that things are preceding normally. I do. I have no reason to believe that Marina Star is off course or off schedule.
And yet the most recent AIS position for that vessel is almost two days old. Can someone explain what is going on? Or is the fault mine and, if so, what should I be doing to see the ship's position and course track?

It's been my understanding that there has been some pronounced pirate activity off that location within the past 72 hours.

I have a pretty good idea what the problem is, and there is only one remedy.
10mg of valium twice daily until the ship makes port.

Funny! Cruel but funny. And nicely done.
I particularly like that it is the Boston Globe.
Still ... UN peacekeeping forces? And Andrea Porchetti? And wouldn't the Canadians quote distances in kilometers which would be translated into miles for US readers rather than the other way around?
But seriously, why isn't the Marina Ace visible?

I've just copy pasted a real ship incident and changed some of the info...
It seems like finally arrived, you'll be driving it pretty soon...

She's back! I just got in, checked and found that Marina Ace is pretty much due south of Narragansett Bay but on a west-northwest course. I don't know those waters and so I don't know the channel that she is in but she will have to turn north soon.
