Not going to your patrol grid

Optimum speed for VIIb type is 8.25 knots and after upgrading with GW Kapselgeblase it's 8.5 knots. The value is different for other types of boats.

Not true.

Recharging the batteries does use up diesel. Even just sitting on the surface at 0 kts on recharge will use up fuel. So you can't 'cheat' by just relying on the electrics. However it's not possible to run on the surface on the electric motors which is what a real u-boat could do to save fuel.

1. As to consuming fuel or not, I'll wait for some modders' opinion - they usually know best for obvious reasons. I might be wrong, yes, but I'm still strongly convinced that loading batteries doesn't consume fuel at all IN SH3.

2. What do you mean saying that they used batteries for saving fuel? IRL using batteries doesn't help to save fuel, in fact it's an opposite, as you need more fuel to recharge the batteries after than you'd need to make the same distance. :hmm:

Hehe, I think the worst flaw in the game is in the XXI, ok it goes faster submerged than surfaced, but as far as I know because it had stronger electrical motors than diesels, ever tried to snorkel around with it in calm seas? Set speed to 8 knots and watch where the needle stops. At 10 knots... Correct me if I'm wrong but when you're submerged your boat creates more drag because more of it's surface is covered with water or not? Guess that's not taken into account by the game, only the maximum speed the boat can reach surfaced and submerged... I can get about 53.000km (IIRC) range out of the XXI that way, bad thing is you're prey for the airplanes, because early on you don't have that snorkel radarwarning reciever.

But the XXI had lower drag submerged. It was designed for high underwater speed and really was the first submarine. Everything before is basically a surface vessel that can dive. You can look at swimmers for another example of lower drag submerged. They stay as long as possible under water at the start using only their legs for propulsion (its worth noting that the primary propulsion is the arms for crawl). Breast stokers even "submerge" during their swimming.
