How far away from the target can i be and still be relatively sure to hit the target with my torpedoes. Can anybody tell me.

Boat stopped at optimal position, weaponsofficer activated, small gyroangle, good weather conditions, slow target, tubes opened, starting eel immediately after new TDC setup = 6000m and more!

I 've made some experiments with invisible targets at 12 km distance - you can lock on for some seconds - and even scored some hits.

What are you after?

I would like to fire at a range between 2000 - 3000 meters but i do not know from how far away i can fire to be relatively certain to score a hit. I have been surfing the internet to see if i can find any articles written by old captains or somebody how would know these things, about uboat attack tactics and launch ranges of torpedoes, but i just can not find this information anywhere.

2000 m to 3000 m is no problem with weapons officers help! My preferred distance is ~ 4500 m - I stay outside of the convoys.

What's your realism setting?

The torpedoes had major problems with depthsettings and fuses, but I never read something about gyroangle. I think it was a question of the overall circumstances - weather, area, own and target speed, position to target...
There should be some data available from the U-Boot Wardiaries. They were not destroyed by order!
Afair the germans needed in average 4 torpedos to sink one ship over the complete wartime.
This includes the major malfunctions in the first years.
(Afair Us ratio was 14:1!)

Sounds great, i am playing the mod "tonnage war" with a 100% realism settings.
Do you know about "timetrawellars" program "Mini tweaker" if you do can you tell me if all the values in the tweak files are based on hex ?

Never tried to play at 100% settings.
It may be difficult to hit from 2000 m and more due to slightly incorrect AOB and distance values. Well - it's all a question of data gathering quality.

And - sorry - I don't use the mini tweaker.
Have you asked your questions in the subsim forums?

I will try the forums, i am getting a little tired of my watch crew being able to spot ships so far away that i can not see them myself. I mean if i am on the bridge with my binoculars and i can´t see anything but water and suddenly one of my watch crew screams "fartzeug" and i take a look and nothings there. If i can not see, he can not see that is the way it must be don´t you agree.
