most of these ships seem to be in transit. Someone from Long Beach said the other day that 66 ships were waiting there (suspiciously cultish sounding number by the way). A zoom-in of ports could show how many ships are anchored - wider views always have ships hidden by their close proximity so we can't tell how many are stacked up.

BTW, I don't doubt they are stacked up at ports. I'm having trouble with car parts and commercial roofing materials... long lead times are killing business. One of my work trucks was parked for 3 weeks waiting for a computer chip.
