Every source I've seen (not just Wikipedia!) quotes a fleetboat range of 'something miles @ 10 knots'.
The mileage varies a little, depending on which source you are looking at, but they all consistently quote the 10 knots figure.
Maybe that's where we got the 10 knots magic number from?
Having said that, I am looking forward to cruising around the PTO with a bit more dash.
Out of interest, what sort of range are we going to be getting at 15 knots?

About commonly accepted figures and sources. Yeah i know. The thing is they are ALL a little too general and a little too vague. As stated elsewhere, the acutal cruising speed ranged from 12 to 15 knots if you look at patrol reports. To give credit where it's due, the changes were inspired by this thread:

I just finally got around to , thinking outside the "@ 10 knot box".
Basically here's how i did this.
I made these telegraph changes:

AllStop=0.00
AheadSlow=0.25
AheadOneThird=0.50
AheadStandard=0.75
AheadFull=0.90
AheadFlank=1.00

At 2/3rds your doing 10 knots. At standard your doing... 15ish nots, and full your doing 18 knots, and at flank your doing 19 to 20 knots.
Underwater, ahead slow gives you a 2 knot turn, 2/3rds will give you 4 knots, etc etc. It all works out logically, and the speeds seem to be what i've read in various readings.
Now the thing about the range setting in particular. I custom matched the cruising speed according to the top speed of each boat.
For instance, a Gato has a top speed of 20.25 knots.
Ahead standard is 75% of that speed.
So 20.25 * 0.75 = 15.1875
I rounded this number to the nearest tenth. So the acutal range in the submarine sim files will be 15.19 @ 14138.4 .
Which is about what the navigator will report as being your maximum range at current speed when cruising.
The 14138.4 i forgot how i arrived at that, but it involves accounting for the flat map. This flat map makes things about 25% longer in distances then they are in real life.
So each boats cruising speed WILL be different, and they'll be no need to click around the speed dial trying to get it at EXACTLY whatever cruising speed you think is the most economical. I've already done that internally. Just hit ahead standard and off you go. (besides it is humanly impossible to manually set a speed of 15.19 knots. )
I do realize that at 2/3r'ds the navagator is going to report ALOT more range then what you probably should have, but i figure in thise case, if someones going to cheat, then they'll going to cheat. I don't want to curb cruising speed for the "honest" players because of it. Kinda like ubisoft punishing honest players with their stupid DRM.
And i have a hang over. I need more coffee.
EDIT:
BTW, before i forget, here's how the battery fix will work out.
Test results for underwater endurance:
Traveling at 1/3rd bell which equated to 2 knots under water, i covered a distance of 97.3 Nautical miles. I had used 90/100 of my oxygen, and had 11/100 remaining on the battery. (Note how even the battery and O2 usage ratio is)
Battery recharge test results:
- At 0/5 telegraph, it took 4 hours and 27 minutes to recharge the batteries from 11% to 100%.
- At 3/5 telegraph, (15 kts) it took 8 hours recharge from 11% to 100%.
- At 4/4 and 5/5 telegraph, it took 15 hours and 17 minutes to recharge from 11% to 100%.
As an aside, yes, right now if you sit still at an all stop, your batteries will recharge faster. I never realized that until i tested it.
