No matter what uboat I'm driving, I use the second-to-slowest setting on the telegraph, which gives about 8-10 knots in a Type VII and 6-7 knots in a Type II, and I rarely have fuel problems.
In the patrol I'm on now I left Wilhelmshaven in a Type VIIb, cruised at that setting to BF16, and arrived there with at least 80% of my fuel on board, have been patrolling at the lowest setting (4-5 knots) and after exactly one month on station I still haven't recieved the 50% warning. When I get the 25% warning I'll head for home at the same setting, and probably arrive about the time I get the 10% warning.
Oh, GWX.
Any questions?
