I have done 4 patrols, 2 out of Kiel(type VII), 2 out of WHV (type IX). Stock SH. Very nice! Found targets and convoys by listening search in the areas of the known approaches.
One target stopped its engine when he saw my steaming torpedo. Very smart. So the reward was survival, sometimes I am a sentimental killer. Is the KI really that clever?
Having fun with a convoy west of Ireland February 1940 the destroyers allowed me to cancel silent running below the transition layer and reload torpedos unpunished. This seems to be not realistic even not in the early stage of the war when the philosophy was, to keep the boat away from the prey. I was in the middle of the crowd, they should have heard the noise.
Overall impression: Splendid Mod! Loads of fun! Thank you very much Mr. Lurker
