Best timing for snorkel?

Sorry Shkval, I didn't quite understand your question.

The subs batteries would charge at the same rate regardless of its speed. You could be at a dead stop, it wouldn't matter. The reason for this is that the diesel that is charging the batteries is not powering the boat. That prop does not turn. Going at flank or slow would only change the distance you travel but not the time the recharge takes.

As for tips/tactics, I would never let my batteries go to 10% during patrols or transit. If you are detected by a destroyer at that battery level you would be in deep trouble. I seldom let them get below 70%, unless I'm chasing an unescorted target submerged.

Hope this has been some help. Good hunting
