Thank for your help :).

I can't install it on "C". But I suppose (I hope) that a mod will correct it :yep:

Honestly, this is modding 101. Crash depth is the depth that Hit point loss will start to incur on an undamaged hull. Crash speed, is the rate at which the hit point loss incurs per second. In other words, one specifies when, the other species how much.

How max depth in the subs cfg file comes into play in SH5 i don't know. In SH4, it is the depth at which the boat will level off at automatically if you press the D key to set dive planes to normal dive. Aka "test depth"

Quote:
'CrashDepth are the depth the u-boat will dive to if you hit Crash Dive.

Max Depth are the depth where the boat will crush'

I don't recall saying any such thing :06:

No you didn't, someone else did, i was just too lazy to go back and attribute the quote. I suppose i should make better use of the muliquote function. :88)

Did some testing with this:

Historic approx. crush depth for a type 7A was 200m

Set the multiplier to 1.15 of what you want it to be.

So in my case I want the 7A to start hull damage at 200 so make it 230.

Is there mod for this? Ubisoft have no clue about German subs, all vii clas subs can easily dive near 200 meters, and some over 200 meters.

Its so easy I hardly want to even release a mod for it hehe.

I will though for others, I will make the 7A-C 200 meter crush depth and 7C41 250 meter.

I can base it off this:

determining actual crush depth is not easy since the subs which exceeded it did not come back..:ping:

the deepest recorded dive by a type VII which I have found so far was 250 meters (812 feet) by U-331, a VIIc, right after it sank HMS Barham. I have been reading Blair's books and am now up to spring 43.

It appears such deep dives were rare events. He mentions two dives by other boats, one to 750 feet (230 meters) and one to 675 feet (208 meters) as "scary" for the crew. Certainly serious enough to be recorded in the boat's log.

In game with a VIIc, I have been down to 220-230 meters, before getting a visual and verbal warning from the chief that we are "too deep". If you immediately rise at that point, you can get away with as little as 1% damage to the pressure hull.

Is the stock game accurate? hard to say, it feels about right to me. Remember that for each 10 meters of depth, the pressure rises by a factor of one over the water presure at sea level, so:

sea level = 1
100 meters= 11x
150 meters= 16x
200 meters= 21x
250 meters= 26x

at sea level, pressure is 15 pounds per square inch. At 250 meters, it is 390 pounds per square inch.

Shouldn't that be 11x, 16x, 21x, 26x, etc?

Approximately one atmosphere worth of pressure from the "natural one" and on top of that one for each 10 meters of water.

yes, you are right. Its been a long time since I learned that formula.

Stock is way off, they had the type VIIC/41 at 300 meter crush depth.

Indeed. When it comes to uboats, it is very hard to separate the facts, from the myths. Especially when many of the myths, are believed as facts.

We have a new record-holder.

On march 11, 1943, U-432, a veteran VIIc on its 8th war patrol but w. a green skipper sank a merchantman. Incredibly, instead of taking evasive action, the boat stayed at periscope depth and the officers broke out champagne to celebrate... :o

...When the corvette Aconit carried out a standard sweep, it was also surprised to find U-432 still at PD.

Aconit dropped 10 DCs which caused extensive damage to U-432 and drove it down to 1,000 feet (307 meters). This depth "...so terrified all hands.." that the skip decided to surface at which point it was quickly sunk by the escorts. There were 20 survivors.
