I am talking from memory and I may be confusing old threads: I remember reading here that escorts detection parameters, in game, of us (u-boat) have also to do with speed and heigh. Again, I am not sure of this.


In my game, GWX3+several mods, until mid 41 or sometimes later, with a calm sea state, decks awash and going like 3 to 5 knots, I could get very close to the convoy and sometimes the lateral escorts do pass like 800m near me with out changing course to attack me.

I also experience the opposite, thinking that it is going to be a nice attack and the sky is sudden full of star shells and the escorts are coming to attack.

Speed, weather, wave height, profile affect detection among other items. I've never heard sub height doing so, if that is what you mean.
I do recall that even the tiny snorkel head was treated by the game same size as the entire sub in terms of detection. Don't know if that was changed over the years.
I've had similar results as your examples both awash and not fwiw. :)

I see. I never manage to get so near a convoy with out decks awash. Well, back to patrol, want to experiment to see if I can get them with out that technique.

There are so many other variables involved my examples could be totally unrelated to whether its used or not for that matter.
For sure post any results you get. :up:

Of course. I am now in a 42 campaign. My late 43 Type IX was down the ocean...:dead:.
I will take some time to get to the early years.



In sake of books, two I have read: No Room for Mistakes: British and Allied Submarine Warfare, 1939–1940 and The Gathering Storm: The Naval War in Northern Europe, September 1939-April 1940.



Both of the same author and quite good books about the first year of the war and what come up from it.
