no, but they should be, because they were in silent hunter 2

They are simulated, I remember someone saying that one of the devs said they were modeled. :know:

Thermal layers are more and more rare the shallower the waters. 150 metres? Nnnnn...never saw one. They might exist, but never saw it.
200-250 and deeper is more like it.

It appears thermal layers are simulated in the game according to the devs, but we have no way of knowing when we are passing one, as there are no temp gauges simulated...

Hello,
" ... thermal layers are simulated in the game according to the devs, but we have no way of knowing when we are passing one, as there are no temp gauges simulated ... "

... and that is how it should be, there was no possibility to measure surrounding water temperature or density. However it was common knowledge there were "hiding zones" in the shallow waters of the U.S. coast, but you would not know exactly where.

If you evade this time you may have to thank a layer, but you can't be sure, next time will probably be different ...

However it is interesting how a destroyer takes the sinking speed of depth charges into account - in the game the charges mostly explode at the same depth as my boat is, even in early years (yes, exterior cam on ... :oops: )

And if a depth charge explodes in deeper water, the resulting radius of the destructive zone or "blast" will be narrower than in shallow waters because of the surrounding higher water pressure - if it certainbly explodes a few centimetres to the hull ... :dead:
I read somewhere that mostly no direct explosions sank your boat, but the shockwave travelling through the water. It would travel right through the hull without damaging it, but it wreaks havoc to the stiffly mounted bolts and unelastic sealings and gaskets. Only the type XXI had some kind of "rafting", separating mechanical parts from the hull with rubbers.

You boat will not sink because of a crushed pressure hull, but because of leaks unable to fix because of the high pressure. Even the pressure hull or bulkheads will mostly not collapse, because the leaking boat will have accomplished even pressure in- and outside before reaching those depths. Modern submarines will develop collapsed bulkheads or hulls due to their stronger design.

Catfish is exactly right, Duli. The thermal layey modeling is present, but there is no "passing through thermal layer, Sir" statement as there was in SH2.

One of the supposed advantages of a Uboat going deep, was the problem it caused to asdic operators. The asdic emits its sound in a cone shaped pattern ahead of the ship. If you are detected at depth, then as the ship proceeds to your location, he is then asdic blind as the cone has proceeded past you. This in reality gave the uboat skipper a chance to change course and depth. I have noticed that in this game this is not modelled correctly, the destroyers can maintain contact permanently, even when changing course, when they are accelerating towards you.

How many people here have ever seen rain in fog? I have not.

I agree. It seems the DD's have a sonar keel that can see everything.

This 'cone effect' of DDs are corrected/improved in Jungman's SensorPak fix, if I have understood it correctly.

Where can I find this mod?

Same here. So many mods............

Here:
http://u-boot.realsimulation.com/
Look for "SonarDC_20.zip"

I think they are..... :|\

I thought it would be easy to find, but I had to search a while. The file is called 'sensorpak.zip', and includes much more that just the sonar fix.

Here is one reference from a post by Jungman:

So this includes the Sonar_DC-fix as well as the other fixes mentioned by Jungman.

This mod should be made more easily available somewhere (or be included in Jungman's signature). Hint hint... A truly must-have mod/fix, and much appreciated!

Hello Nopileo,
thanks for the heads up, must have missed this one !
