It's not on a chart that I can see. I don't think it's a ship.
There's no wake and no detail like a ship would have. An oil spill?
It could be just a smudge on the picture. There's a few more blobs
like it just to the south.

Would you see a wake? It looks like a ship to me. Maybe one that is
anchored.
