Basically, there are two ways to submerge a boat: dynamic diving and static diving. Many model submarines use the dynamic method while static diving is used by all military submarines. Dynamic diving boats are submarines that inherently float that is, they always have a positive buoyancy. This type of boat is made to dive by using the speed of the boat in combination with the dive planes to force the boat under water. This is very similar to the way airplanes fly.

Actually there was nothing faulty in Krauter's explanation of flight dynamics that I could see matey - mind you it might have been obscured in all the hot air you've been blowing

Oh yes there is. I explained them in the earlier posts. If you want to disprove them, I welcome you to do that.

Kinda shot yourself in the foot there matey , unless you were talking about Model submarines all along.

I found it funny because its an element that exist in both situations. It's just that there is more complexity in the other method.

But my MAIN point about the similarity between u-boats and airplanes was not about this. It was about low vs high pressure. God forbid if you had asked me, i would have told you.

How do you do that, when you have 10+ destroyers over your head, listening for the faintest noise to locate you and smash you into pieces???

Go for minimum speed ahead and use silent running and go a bit deep and they wont hear you. This is my experience, it doesnt take much more than that. Ofcourse they will try to find you randomly and perhaps follow you by share luck, but they wont find you.

EDIT: If you have the VIIC/41 u-boat and you have a trained crue (with abilities) you are able to take your u-boat down to almost 300 metres. But 200 metres is more than enough. When you are that deep your u-boat will be beneath layers of cold water. Cold water shields sound better than hot water. Use these layers of cold water to hide the engine sound.

You just go for neutral buoyancy then dive as deep or shallow as you want using the dive planes. Of course based on your pressure hull capability.

It's the same principle with airplanes. The higher you get in the air the less dense the air will be and the greater speed will be needed to maintain straight and level flight.

It's not a bug. It's a shame they "fixed" something that should not be fixed.

Consider the depth when you dive: (The "square" was a typo, it should be cubic)

It is indeed a bug with VIIA/B after 75 meters. A confirmed bug afaik that never made the last patch. With later models it doesn't occur before 150m or so.
Second, this "feature" is totally meaningless untill we get the means to control and trim the boat since the crew obviously can't do it, even with the skills maxed.

I did my test with the VIIC/41. And it doesnt happen until you are below critical depth, so there is no problems with the VIIC afaik and happens only when speed is low or zero.

He didnt mention what type of u-boat.

There should be a 'maintain depth' button on the interface.

[Krauter]

There is.. if you're using Churchs Keyboard Commands it's A

[Ragtag]

It doesn't help!

You know I love watching people gnashing their teeth over this subject. It (and a few other minor items) are inherited behavior from SH4. Seems like most people here aren't aware of that for some reason.

So here's the short version:

After 196 -200 meters (or 600 feet), there's this magical barrier you pass where the submarine's pumps can't keep up with the leaks. As i recall from watching the development of the NYGM anti-hummingbird mod, your sub is always leaking. This particular behavior, is inheirted from SH3 to some extent. You don't see this because a leak below a certain amount is not reported on the damage screen. So as you cross what i refer to the 200 meter/600 foot barrier, your boat loses boyancy and starts sinking. The only way to stop the decent, is to accelerate to flank speed.... err im sorry.. "extreme speed ahead".

Order rise all you want, but your boat will not move to a shallower depth until you blow ballast, thereby increasing boyancy. Reduce your speed , and you start to sink because you have too much negative boyancy. Hency why i say, pumps can't keep up with the leaks after 200 meters. (edit: supporting evidence is behavior in trim gauges. They peg out after 600 feet) How to adjust the pump rate? I never did figure that out, or even if it's possible.

An interesting side note is that crash speed (at least in SH4), seems to have an effect on this. ( http://forum.kickinbak.com/viewtopic.php?f=70&t=1885 )

I think I'll rather command a Destroyer than a lousy sub.
