I experienced this in WaW a few days ago:
I was attacking a Red convoy up around the Arctic. PQ convoy route, I believe. I was submerged and the wind was HOWLING out of the north. A big ol' liberty cargo came up out of the fog listing heavily to port (cuz of the wind, I imagine). I had never seen a liberty cargo before in GWX...wow, the detail was amazing especially as it loomed out of the fog and fighting through the breakers like that. Drooling, I slammed 4 fish into her at 88 degrees AOB and from about 1200 meters away. Then I went deep fast. She broke up and went down and the escorts must have had more trouble than usual trying to find me because of the weather which allowed me to slip away. Uber cool.
