Can't I go ten feet without hitting a uboat?
 

My last three patrols have had me nearly hitting a uboat. All three were resupply subs according to my weapons officer (what's his abbreviation?). And I do mean hitting. I had to alter course and speed each time not to run into them. How do they know to plot a course right in my way?

So, in GWX3.0 do these boats actually set out from a home base to their final destinations prior to being available? Why do I keep seeing them coming out of the Atlantic side of the channel in Nov '40 - Jan '41?
