Well considering my Carribean hunting grounds thread has been highjacked by range finding juckies i did some maths
Basically i can travel 84nm using batterys for the same amount of fuel as it would cost me to travel 21 nm on diesels.
Quick maths for you.
SUBMERGED
23 hours submerged @ 3kt = 69nm
3 hours recharging @ 5kt = 15nm
Total 84nm for the loss of 3 hours fuel at "Ahead slow"
SURFACED
3 hours crusing @ 7kt = 21nm
Total 21nm for the loss of 3 hours fuel at "Ahead slow"
Doing this increases range by 75% in my book, did i go wrong somewhere?
