Man the fog is a deadlier than an destroyer!
I was cruising my way trough the channel between Ireland & England. Weather was bad, wind 15m/s, fog heavy. I was almost on my patrol grid so I stayed on the surface to get there faster. I was on nav map and TC was 1024. Then it dropped to 8 and I saw this ship icon on the map. I put quickly TC to 1 and ordered flank speed and rudder full to left. Then went to conning tower to check, how close the ship was. I almost had an heartattack! All I saw was the grey metal of the C3 cargo ship!!!
