Best timing for snorkel?

Shkval · 03-28-12, 11:59 AM

Few questions... how long does it takes to fully recharge depleted batteries with snorkel? I have red somewhere that is best to use snorkel 12x20 minutes a day... or something like that? I can't find that thread

... is Jungman's fix for snorkel detection included in GWX 3.0 gold? If not, where can I find it? Links are dead in old threads...

good question, i never effectively used the schnorkel
air attacks from schnorkel detection are way too close for comfort, i find i'm better off running on the surface and diving on radar detection warning beyond visual range

Batteries would charge at the same rate with snorkel as they would on surface. One engine would charge batteries and one would power boat.

Playing with snorkel and not having late war sensors is death. You won't know what hit you.

OK, I know snorkel is dangerous, but you haven't answered me anything, anybody some good tips, tactics? What is the best ratio of speed per knots /spending-recharging batteries? I know that with early VIIb you can get about 200 km underwater at 3 knots 'till 10% of batteries... with one surfacing for air about 8 minutes long, and that you need about 100 km recharge at flank speed... anybody has some better idea?

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

Well, I tried to measure time to recharge... after 3 hours submerged, I had to be surfaced at least 1 hour 15 minutes to recharge...few times even longer almost 1 hour 45 minutes... that was in bad weather... but when weather suddenly calmed it took only 35 minutes

... so what to do... dive and wait for better weather? Or surface, order flank speed, and pray not to be caught by radar for hour and a half period of time?
