How to escape from destroyers?

[anjutosi]

I'm new to this game, but experienced in Silent Service running on a ATARI and I was a war navy officer (surface fleet). When atacking convoys I can go to my targets, hit them, hit 2 or 3 destroyers, but at some moment I run out of torpedoes and mus escape from destroyers. How can I do it? In real world, full back for some minutes and after ahead full creates turbulence int he water that can cheat the sonars. Does it work in SH3?
Thanks

How to escape from destroyers, you ask?
Very carefully

Well, id recomend you change your entire approach to convoy attacks. Pick your high value targets, fire your torpedoes when in position and as soon as that is done start a dive to 150 meters while changing course away from the convoy. Depending on the proximity of destroyers choose the speed of your decent, personaly I wouldnt go over 4 knots in a VII or IX boat unless you are evading depth charges, and when at your target depth go silent and listen on the hydrophones for aproaching destroyers and take evasive action if nessesary, otherways make your getaway and take another pop at the convoy the same night if possible, if not shadow it and then hit it again the next night till you are able to or untill the convoy has been sent into the abyss.

Do your best to stay out of the destroyers arch. when hes turning into you turn away from him, when he drops he depthcharges blow ballasts and all ahead flank. keep turning and dont let him get a fix on you. Early war, the lower you get the better because ASDIC didnt have the capablility to go very deep.
Good hunting!

Never heard fo waterturbulence being modelled in a game. (not even Subcommand/DW) If you're still on the outside of the convoy and surfaced you can sometimes gain distance by flanking the h*ll out of there before the torpedos hit. An exit course perpendicular to the convoy course seems best imho. That is best to increase the closest point of approach. I wouldn't go reverse as that speed is slower than forward. Don't waste time firing torpedos at DDs. Use that time to evade. Or if already inside the convoy, turn more inside the convoy to cause traffic jams. And at the same time dive as deep as you can to get out of the active sensor-cone. Set speed to 1 knot and silent running if not allready. Turn to put your stern (or bow, but that closes the distance, what to do depends on being surrounded) on the pingers to present a smallest aspect angle as possible to them. Now all you need is patience, nerves, and luck. And lots of the latter!

Thanks for the tips. I'm gonna try

Turning map contact updates to On has helped me. I know that it's "cheating" a bit but it allows me to keep an eye on the escorts & stay out of their detection arcs (hopefully). It's been especially useful in the Med where the convoys have been small (1-2 merchants escorted by 2 or more DE's).

This is really cavitation, where the propellor attempts to move more water per revolution than there is water available; at low speed/high engine demands. It's noisy - very noisy - and causes bubbles to be created (a la Boyles Law).

Best to increase speed slowly.

Re, you're question: go deep, go silent, and keep the engine revs slow (below 3 kts). Turn frequently!

[Weiss Pinguin]

Be sure to keep as quiet as possible. If you go over to the Chief Engineer's station, you can see the RPM gauge. Keep the engines from going over 100 RPMs, to cut down on noise. Slow going, to be sure, but patience is a vital part of evasion.

Oh, and luck :p

I see, that makes sense. If it wasn't like the analogy of blinding him with a flashlight in a pitch black room. Now he'd know where to go.

I was thinking more like the displaced water creating sort of a horizontal mushroom cloud deflecting/distorting the active wave. But I don't know if that works at all in RL.

My tactic,

Speed 1 knot, periscope depth. When the destroyer is closing to you, flank speed
and turn right or left for 10 dgr. When it has been passed lower your speed again to 1 knot.

That`s the way i do almost escape.

one tactic i have used with quite a bit of success
fire your torpedoes at the target you want.
Dive around 150-160 meters.
make sure you dive and keep under the middle of the convoy as the destroyers have a harder time picking you up, as because 1. all they can hear/pick up underwater would be tons of merchant engines and 2. they can't manuever as well if your under a convoy, as they (destroyers) have to keep themselves from getting trampled from those large C3. hope this helps.
