Okay, well, since this whole issue of not enough guys on the boat is a popular complaint - let's run our own little investigation, shall we?
My understanding that a norm for a Type VII boat was 45 men (ranging between 42 and 50 or so, depending on boat, year of war, and so forth).
Who were these men, and where were they during surface running, submerged cruising, and on battle stations? What were they doing there?
It would be great to come up with a diagram of the boat to help us along.
Here is how things currently stand (each red oval thingy represents a man, 27 in total at present), at least on surface cruising stations.

Who can help fill in the blanks?
