Theres is one more variable that none of us has considered. The ballast tanks. There were 2 ballast tanks that were routinely converted to fuel tanks to extend the subs range capacity. This ability was never "advertised" when discussing the subs range, so most posted data leaves this out.
So I'll see what I can find on its capacity and then maybe that amount should be added to our fuel supply? Just a thought.
