I noticed a similar problem with how to 'use' the XXI. The Type IX has a range of over 60.000km travelling at ahead standard (10kt), while the Type XXI can struggle with fuel. It does have the Walther turbine which allows you to get to speeds over 20kt even submerged, but I don't really know what the application for this is, because it runs on it's own fuel too.

I did read that the Type XXI was the first U-boat (and submarine) to be designed to cruise underwater, so maybe the idea is that you keep submerged with radar and only surface at night to recharge the batteries. Just a thought, I don't have it currently in my campaign, but I think the ahead standard speed while submerged is 7kt (correct me if I'm wrong).

I find that the Type XXI is a great boat, especially with it's fast reloading speeds, but it does suffer from fuel problems, especially compared to the Type IX.
