What is BDU thinking.....

U471 is a type VIIC, correct? You should be able to steam anwhere from Florida to Quebec City, and return to France - I know, I've done it in a VIIC. Crusing at 7-8kn you can stretch your range to 15,000km or more (weather and sea conditions depending), which is enough for a round trip from France To NA, with a small but comfortable margin for error as well. Charge around at higher speeds, or go way off base course to chase contacts and you won't make it.

I think the longest distance I ever sailed in a VIIC was close to 19000km, but I practically had to get the whole crew on deck to paddle the last few km's into the pen again.

Note that U202, a type VIIC, sailed from Brest to Long Island and back to Brest (landed sabateurs on Long Island) in May, 1942. She had no refueling stop either. The round trip took her about 2 months to complete (she was running submerged many nights, as secrecy was essential given her mission orders - she had to arrive off Long Island undetected, and remain undetected for some time after she left her "passengers" behind).

You could actually run on electrics and surface to recharge the batteries without fuel......................strange anomaly

Yes, 7 knots, will gave you enough fuel to get there, back, and operate in the area. You may have a cup-full of diesel left when you get back
