you could also "sit" that out til the enemy runs out of deptcharges, i had a very immersive hunted session, over 3 hours and 6 dd´s, was nearly dead by dc damage and i thought allready that is the end... but than they decided to return to the convoy, together with creating a wide back / side covering screen preventing me to easyly go into a new attack position. After hardly beeing able shadowing the covering escorts duo to engine damages, they tryed to lure me away from the convoy, but i smelled this trick, couldnt belive that :haha:

yes... that when you hunt convoys... but when you hunt capital ships or aircraft cariers the DDs will hunt you untill you will be dead if they will spot you... they have not a convoy to return back at it... and usually they have an HK with them... so if they spot you , then your chances to survive are ZERO:DL

How deep where you in the DC attack? As soon as i go under 150 meters the dc,s cant touch me anymore .

You know the other day I witnessed a DD sailing in circles about 4KM away from me. Was that an old search tactic or something or just a bug ?
Kev

there must be something wrong with your soup i guess, they hit me very good below 150 meters, they also throw DC´s infront of me if they detect my speed or just by guessing sometimes... maybe the current year is responsible for it ?

Sometimes a bug shows its head: a DD will "lock" on you and stay there circling forever, no matter what you do . Save and reload game and the "lock" breaks .

Could be its july 1941 , what year are you in?

November 42

Are the AI escorts able to detect depth soundings from your sub? There are times I want to know how much deeper I can go when escorts are around but I'm hesitant to hit that depth sounding button in case the escorts can hear that.

Had a good evasion experience last night. Attacked a very large convoy somewhere SE of Ireland and I was too slow to get out of dodge before all SIX destroyers came charging my way. For about 2 game hours I tried to evade these guys at a depth of about 130m. My battery was down to 25%, I had sustained some damage too. I ended up using the decoys in conjunction with ordering Flank Speed for about 10 seconds. I noticed they kept DCing the point where I let go of the decoy. They lost me after this at which point I sat almost on the bottom completely silent waiting for them to give up and return to their convoy. They eventually did and I carried on my merry way.
Are using decoys in this game "historice" or "realistic"?

Using IRAI difficulty settings of 85 low, 95 high

what i think is that the bold decoy is more a shild against asdic, it just created bubbles in the water to create a covering screen which stopped the asdic to hit the boat. I dont think it also created engine noise, and iam also not shure if the DD`s sonar crew was thinking that bubbles would be the enemy sub or simply "wtf, where is he gone", but for shure having a endless ammount of "bold pills" on board is unrelaistic it seams.

If you ask for depth under keel. Yes the DDs will hear your ping:yep:

I think they are limited

My wild guess is that it would also shield engine noise to some extent if on the line between you and DD - bubbles change sound propagation pattern not only for ASDIC and there is also bubbles forming sound. But engine noise go not only in straight lines, hence complete muting could not be achieved of course.

But that's only my very wild guess.

The purpose of Bold (bubbles) is to create a signal equal to a sub in the enemy ASDIC screen. Later ASDIC operators figured out that of two signals, the one not moving was bold and the other the sub, so ze germans developed Sieglinde, similar to bold but moving at a speed of 6 knots.

Recently TDW released "Water_Disturbance" mod which, to simulate disturbances caused by DCs explosions, create a virtual bold decoy for each explosion (45 seconds).

It has great implications to evasion tactics, although I still have to figure out exactly what. Any suggestions?

Anyway, this later mod is a must have when using evil IRAI.

Even if DC are only dropping to 100 meters and you are 150 meters, your boat should still have very severe shaking.
Explosion Shock Waves travel very far in water. Even your own Torpedo hitting a target at 1000 meters away should give your boat a very rough shake.

Check effects of "JD Realistic Depth Charge Damage and Shaking 1.0" MOD UBOAT DANCING.
This MOD only effects the Boat. Not the Crew. Crew Animation and Crew Sounds still needs to be worked.
I have many years experience working with military grade High Explosives. and YES, big difference between civilian and military HE. I think this reaction to DC explosion is far more realistic then stock setting.

:oNOTE: if using "JD Realistic Depth Charge Damage and Shaking 1.0" MOD. DO NOT try to hide on botton. You will end up being bounce on the sea bed doing extra damage to your boat. I learned this the hard way.:oops:
