but according to the thing
you get the best fuel consumption at 2/3 speed, i always thougth that the slowest you go you consume less, but the thing doesnt seem to say that
i was thinking maybe this is a mistake with the equation it uses to calculate this , so whats the deal?
whats the best fuel efficent way of going
with batteries ?
and with diesels?

Slower isn't always better.

The tradeoff is: are you working the engine in its power band, and not going too fast, generating lots of drag?

The optimal for our subs here is...about 2/3 ahead. You'll notice that's not really 2/3 of your top flank speed.
