A few times yes, especially with formations hugging the coast (as you noted). Had one tanker turn to port and run himself right up on to land, so close it was to the shore line.


But it's rare, and by the time I've left the North Sea I no longer encounter any of this, and anyway, I'm hunting far from the coast at that point. No doubt there are pathfinding or logic issues with the formations, but probably down to location. In the open ocean it seems to work much better, and I've not seen anything like your image in the open sea. Yet.
