I just look at my fuel gauge and go slow. :know: Close enough for me.:lol:

I map my speeds to my preferences
1/3 to creep speed
2/3 to about 1/3 (slow)
standard to economy speed (10kt)

I know it does not match the dial, but captains were never restricted to the telegraph - I just prefer to have a keyboard mapping to the speeds I need, not the speeds marked on the telegraph.

Was standard ahead really higher than 66% throttle ??? Our telegraphs make no sense, although it was partly because of the electric drive.

Yea I had trouble with fuel on my first patrol.

Then I figured out I had to conserve and use some planning.

Conservation is indeed an issue which admittedly I sort of neglected.

However, still an issue remains with the ability to have ready the information of range given current fuel state and in this the game seriously lacks for no apparent reason.

Otherwise, going around with 'guesstimates' might give the game an arcade sens of trial and error but takes away lots in terms of simulation.

Yes and no, it would be nice to have that function but this is also a guess as well. The subs had a range of about 10000nm. I agree with you, need a simple estimate, same as we had in SH3. All in all, if you conserve or plane a stop at another port to refit, patrolling and lack of fuel should not be a problem.

Watch out for a damaged batterie set. Sometimes the batteries won't recharge further than say 85%. Your recharger will still try to recharge yor batteries. This will DRASTICALLY reduce your ability to make homebase. Switch the recharger manually off in this case, everytime you resurface.

Normally sailing at 2/3 will give the best range/fuel ratio.

Hope it helps.
