Looking into this showed this so far to me as I can interpret. The canal block may not actually be the target of attention I think. Exposing that ships frequently turn off their tracking & change names mid-route &load/unload/exchange cargo at sea instead of in port beyond registering loading/unloading may be the key. They oft meander around just outside the Straits of Gibraltar & that may be the direction to look. Loads of the ships went the long ass route around Africa instead of waiting in line for the canal to open. Here is what got my attention about this whole thing...remember the oft mentioned "Red Castle" and the "Key" to unlock things? Well...take a look at Gibraltar's flag...

I am no decoder or math genius for that stuff...but this seemed quite curious to me & rather hard to ignore.
