Is there any economy/strategic game about delivering goods with cargo ships, containers, etc.? I would love to play it.

Ports of call https://en.m.wikipedia.org/wiki/Ports_of_Call_(video_game)

That revives memories :) I used to play it alot on the Amiga. Interesting to see, that the game is still alive. Unfortunately currently not avialable on iOS or the Mac :(

How do they sail into Russia? They would need their own AIS transponder and a valid ship registration, the Greek/Turkish maritime zone and the Black Sea has a tone of coast guard and military activity and you need to Lee-register/declare traversal. Going into Russia through the northern sea doesn’t seem to be viable either.

I would assume that all bets are off once they reach international waters?

To get through to Russia they need to pass territorial waters, you ain’t getting into the Black Sea or through the Aegean really with your AIS turned off.

Now it’s even harder due to the migrant crisis the waters are very heavily patrolled and anything bigger than a dingy will light up on radar.

Or they could just turn off AIS broadcasts?

Try doing that in the Aegean not to mention the Sea of Marmara / Dardanelles and lets see how that works out.

They might be able to sail into North Africa and then arrange for fake papers and ownership transfer but I would really like to know how they would sail into Russia without raising any alarms.

The Russian coast of the Black Sea can only be accessed by passing through Turkish waters. And the other Russian coasts are relatively far away, challenging, and dangerous to sail to in a pleasure yacht.

There are pirates (thieves, but I like Pirate better?) whom were renting luxury boats in the Mediterranean, and stealing them. They would fly to Europe, and dress like rich fancy boys. They would then rent the ships for vacation. They would take the transponder off the luxury vessel, and put it on a toy boat. The owner would check on his vessel, and it all looked fine. Meanwhile, the thieves would have the boat in Ru…

In a past life I used to take (smaller) boats from Miami into the Bahamas and back. Everyone always warned me that the US coast guard would stop any boat entering US waters but I couldn’t tell you a single time it happened.

Grant it I wasn’t traveling on multi million dollar yachts, but sometimes what you expect to happen and what actually happens are two different things when it comes to enforcing laws.

In a broader sense, they can be considered as hackers.

Making business harder for tourists and renting places is neither cool nor "hacking".

What? Don't some computer hackers also make business harder for regular users? Maybe you have a very different definition of hacker.

There's some interesting anomoly at the north east top bit of South America (both Colombia and Venezuela) where some really fast boats are regularly skipping across land.

Same thing seems to be happening to Great Lakes freighters crossing UP of Michigan over land.

Guess: Interpolation between actual GPS samples.

Does anyone know where they get the data for these shipping map sites?

Modern vessels are required to have a AIS transponder. This is a radio that sends the ships speed, position, angle and optionally their destination around by marine (VHF) radio. These maps are probably made by having thousands of receivers recording the AIS data.

There are satellite networks that can pick up AIS broadcasts from almost anywhere on the planet. So you can track a ship in the middle of the ocean with a few minutes delay. Pretty amazing to imagine how many signals these satellites have to process at once and how weak they must be after making it all the way into space.
