Here's a trick of the trade: When the wabos explode, you have a brief window of opportunity to run your engines at full speed without the DDs hearing you. You can use that burst of speed to change depth & course to your advantage. The window closes about 30 sec. after the last explosion. Then you want to drop back to 1 knot (not just "ahead slow"; 1 knot = 50 rpm), selected on the alternate speed dial. Hope that helps!

Ciao,
Wayne

My rant was well justified. Now I know its a bug from altering depth straight after a crash dive order, it shouldn't happen again now i know how to avoid it.

On a much brighter note, I ran into a convoy in thick fog outside Gibralter on my way back to La Rochelle. Took a shot in the dark and fired at a 14000 ton Ceramic Ocean Liner from 2700 mtrs, with a 4 torpedo salvo. 3 out of 4 torpedos struck home sending it straight down.

Before I knew it I had THREE destroyers bearing down on me. I had to dive right down to 250mtrs, but even then they were still able to find me on their ASDIC. With the boat actually holding depth now, I was able to command the boat properly. I played cat and mouse for a while before I finally managed to give them the slip and they started to lose sight of me. Decoy's didn't seem to help much though unfortunatley when I used them. But that's what I'm talking about. Despite sustaining some minor damage to the flak guns from a few close cans, I loved every minute of that depth charge attack.

But it does make you wonder what the real guys went through. It must have been a terrifying ordeal.

But, after leaving La Rochelle November 1942, U128 successfully made it back and docked back at base on April 9th 1943. Some 5 months at sea, what a cracking time it was.

Not sure about the VIIs (though I didn't have any great problems with them during my last Atlantic career either IIRC), but at least the series II in general seems to behave pretty well in this regard.

In a duck you can order 0 knots forward by putting the needle somewhere between the 0 and 1 marks and get some 50rpm off the electrics, which works fine in both being quiet _and_ maintaining depth - but ONLY IF you're not damaged! Have a leak or two and it all goes haywire, because then you'll need at least 2 knots if not more... plus the repair team binging and banging your boat back to shape, too

Yah, and thanks from me too for enlightening us about this particular bug Haven't had this happen to me so far - far as I can remember at least - but still, one can't avoid what one doesn't know about, no?

S!

then order a different depth before the boat gets down to the 75m(?) that the crash
dive ends at your boat will become less stable at low speeds.

Wait until the boat leavels off after a crash dive before ordering a new depth.
WOW good to know,I always thought it had something to do with going silent,it would sink while being hunted,not all the time tho

Good to know that.
I was just been DC'ed by three ASW trawlers and it was crazy and nervous. I went to periscope depth and saw them leaving the scene.

Then placed an eel to two of them!

I'm in a similar situation off the North Western Approaches just after sinking an Ore Carrier in convoy. Just cannot hold depth at silent speed, the boat just slips down slowly by the stern until you increase speed to get to a shallower depth. Of course, the escorts are then on to you and give you another bashing with their depth charges. Currently heading away from the convoy at 180 degrees in an effort to give the escorts the slip. To a degree this is a frustrating situation, but I agree with Kpt Lehmann in that I look on it as a bit of added realism rather than a bug and a challenge that the Kaleun must rise to if he is to succeed in being a successful commander.

Yeah, but if the boat is sinking unless you go 3kts forward, and the repair team is banging away, then what the h*ll is there to do but surrender in the long run, because the buggers will still hear you no matter what? The weather, granted, may come to your rescue (as may decoys, etc. too if used wisely), but other than that...

This isn't a whine, so please don't misunderstand me now. From what I've read they did hear you pretty easily if the conditions were good, and you were noisy. But if those are the circumstances then how exactly _can_ you slip away - or can you just not?

Unfortunately, SH3/GWX doesn't model this behavior. A shame, since it would make a big difference to in-game tactics.

HOWEVER...if the sea is rough, and you stay at periscope depth, and you've only got one escort to deal with, you can stick your 'scope up to check when you're in his baffles and order flank speed at that point. By zooming away in bursts it's almost easy to evade them this way before they heel round and start bashing away with ASDIC at your last known position.

I have had this problem too... what worked for me is to manually adjust the RPM (right click on the engineer) on the dial so the boat makes barely 2 knots, mostly it is just enough to keep the boat stable and still quiet enough so the destroyers cant here you.

However I will also try the "not ordering a new depth before the default crashdive depth is reached" tip.


Little question on my part:

IRL rough seas made it harder for escorts to detect a U-Boat... SH3/GWX models this right?

If you are at periscope depth, yes. The waves will help mask you. It definitely works - I have used this tactic many times.

Indeed without the rougher seas I have passed on a few later war attacks.
I'm not sure if it is the waves, the extra noise of the ocean, or the escorts being tossed about. Perhaps a little of all that jazz.
I've also set 1m below periscope depth and just raised the scope a bit more to keep the top of the conning tower lower. Rarely, if ever do I extend the scope all the way. That is like a signal flare.

I would also like to add; CrashDive is overrated. I think we just like the sound affects at times. Tip? Develop escape tactics without it.

edited to add; I bet the guys tooling about in those IX sonar magnets have a tougher time

heh, didn't know about this bug...does explain some things though:hmm:

Now, I never use crash dive in a surface contact situation, except possibly for flavor, because I generally just proceed slowly into the deeps (if the hunter is far away enough) and I also like to use the rough weather (which seems to stalk me) to evade at shallow depth. This is required by the fact that I tend to hunt in shallow waters like AM36 and the Irish sea...

As to not being able to maintain depth, I'm sure this happened to real life captains often enough, with all the possibly fatal consequences involved. I do agree that it could be game-breaking, but sometimes you just have to play the hand fate deals you....
