I bop along the surface until I get my batteries charged & then submerge, stop & listen for a while.
Then I set 1 or 2 kts & hit TC at 8, 16 or 32 & watch as 1 hour clicks by. Then I stop & listen for a while. I keep doing this until I hit the first redline on the Batteries or the air is close to redline...(whichever is first) then I surface & recharge again..
It takes a long time to go anywhere, but I have had some success...
The only problem seems to be that I am now in August 1941 & aircraft are really ruining my battery charging. In my old campaign with my older crew I have spotted them in time, but I did two brand-new patrols in 1942 & both subs were sunk by aircraft on their first patrols. I mean, by the time I got the warning they were just dropping the bombs...they didn't miss..I didn't even have time to hit the "C" key.
