Why game give to my U-4 TypellA missions so long tistance.???.when i reach there i lost almost 75% fuel and i tried tu use as much possible pattaries...but even then i dont have fuel to sail home.. http://forums.ubi.com/groupee_common/emoticons/icon_confused.gif

Try using the slower engine speeds and you will be fine. After your first patrol you should have enough renown to upgrade to the second TypeII with 3 times the range. But, the first mission is not easy to go to. Only use slow ahead or 1/3 except when you are in a battle. It worked for me!

Plus, you only lose range by using your electric motors than your diesels.

Using batteries is to save fuel is not really usefull, as they have to be recharged by running the engines with more fuel or using one engine to recharge and one to move (at least in RL).

As it was said, going very slowly, even crossing the wind, instead of moving against helps saving fuel. But then, you got to be reminded, that it's not neccessary to reach your patrol area. Your job is to sink ships and if you do that, nobody cares where you are. http://forums.ubi.com/images/smilies/10.gif

But then you'd loose about 700 points (at 100% realism).

Actually, I would disagree with the statement that running on batteries "wastes" fuel. Actually the opposite seems to hold true. -

Yes, the batteries must be recharged, but the fuel cost is less to recharge than the fuel required to run a like distance on deisel engines.

In my type IX-C boat I have a max range of 25,000km at slow speed (13450 at 10kts) deisel engines. In my current mission I was assigned to EB66 (10,000km one way) and travelled mainly on batteries, surfacing only long enough to recharge them.

I arrived on station at EB66 with 75% fuel reserves. A savings of about 15% compared to travelling the same distance on deisel fuel, which would have left me with only 60% reserves after travelling the 10,000km. (10,000/25000 = 40%)

Just my personal observation for long distance patrol and fuel conservation. Travel at slow speed always. Submerge upon 100% recharge and surface at oxygen 50%. This worked put well for my voyage.

SLOW? Yes! - Worthwhile? Yes. I have the fuel to spend now in chasing down my prey and even am looking at a run up the Atlantic coast of the USA before returning to Lorient. -

Note: I have upgraded engines and batteries, but the strategy should hold true (if to a lesser extent) using just the stock issues.

It's only poorly simulated. In reality this wouldn't work so well.

P.S. Fix this!!! http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

Exactly. http://forums.ubi.com/images/smilies/cry.gif

You always waste more energy recharging a battery than you can ever get back. It was a LOT worse in those days, considering the chemicals used in the batteries and the sluggish machinery used to recharge. As I said, you'd have to run on a single engine in RL to recharge.

If the overall energy was more when using batteries, that would mean you can run any reactor storing the power in batteries and get more energy from it than not using batteries. Don't think so.

The propulsion is really that poorly modelled!?

The abolutely most efficient way of travelling is by using only one diesel, at the lowest acceptable speed. As soon as you start messing about converting forms of energy, you will lose - a great deal.

Some simulator. http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif

And that is also not "realistic", every propulsion system has an rpm at which it runs most efficiently. If you go slower you waist fuel because at lower rpm a bigger percentage of fuel is used to overcome internal friction. If you go faster then you waist fuel because the proppellor starts to slip through the water (it starts to cavitate). There are more things which influence the optimal rpm for an engine but at the moment I cannot remember (well I'm not a ****** engineer, I just call them when something brakes down http://forums.ubi.com/groupee_common/emoticons/icon_biggrin.gif). If it would have simulated properly you would had to run at something like 1/2 ahead or so.
