Obtaining information about cargo ships

[Balthazar]

How can I get information about which cargo ship will depart from which port and what its final destination is?
There should be a global cargo exchange and any ship that is in the area or will be in the area in a few days will pick up the cargo.
They know where they are going maybe a week before, the forwarders who pick up the cargo from the exchange know this too. It should be the same logistics as international truck loads.
I assume the port authorities also have information about incoming ships. How can I get information as early as possible without arousing suspicion. There is an application that tracks ships in real time and has information about where the ship is traveling, but it is updated after the ship leaves and is not useful. Traffickers have information about where each container is traveling to, what the cargo is, which company is the recipient, they know everything.
Does anyone have any idea how I can get information?
