Skipper you are shark bait.
If there are a few fueling ports between your home base and your assigned task, you may be able to run at "Ahead Flank" between fueling ports, but at the last fuel port to your assignment area I would run at "Ahead 1/3" and fast time it. By doing this you will have fuel enough to reach your nearest fueling port ( after the battle ) then the home base they changed on you. Remember though stay under during the day ( running at 1 knot to save the batteries ) and on surface at night. Gotta keep an eye on those port changes.
