On fuel consumption
The fuel usage is now scaled by the geographic position as well as the heading. If you're further North, you draw less fuel while heading East or West. This might sound weird at first, but this system ensures, that after travelling great distances, the remaining fuel in your bunkers will be the correct amount.

The courses plotted follow a rhumb line. If you draw a course along a great circle, the travel distance will be reduced accordingly.

Thanks

@DECAFBAD Understood.

In UBOAT, drag is around 1000 times greater than in real life. There's a reason for this that I won't go into.
I tried for weeks to modify the way drag was calculated and every method failed. As I found out, this is because it isn't even exposed to the scripting engine, and instead it is calculated in the native memory space of UBOAT.
Even though this is only part of the whole equation, even this residual drag is greater than what the actual value should be. So in the end, I don't believe that it is practical to have a dynamic model of the propulsion system in a mod, there are just too many obstacles.

Reducing the thrust force makes the boat slower, but the speed becomes very unstable due to the immense drag. This crippled gameplay too much, so I've opted to remove it to make this mod have the other beneficial effects.

Not to be a dumb dumb here, but does "Historical surface and submerged speeds for the Type VII" being crossed out mean that this mod no longer add's this feature, or that it's broken in the current release?

Thanks for testing!

Also I did test it and it is not compatible with the device energy mod. It basically makes all of the battery values appear as 0 and the game tells you the batteries are fully depleted

Many of the upcoming features you describe sound awesome and I would love to see things like that incorporated. Awesome ideas and good work so far. Look forward to playing with them

Haven't checked it out.

Got to get back to this from another angle. Acceleration will not be fixed because of the way UBOAT breaks when I try to alter drag.

Will this mod work with a different mod that changes the batteries? Such as the Device Management mod? I really like some of the features of that one, but I am interested in the idea of historical propulsion values

Any updates?
