The Crash Dive Blues! thread is here http://www.subsim.com/radioroom/show...ighlight=blues

Let me start by saying that the interrupted crash dive behaviour is a evident in a vanilla install of SHIII 1.4b, this "feature" is brought to the fore by the NYGM U-Boat Mod.

If you order a crash dive and before the u-boat reaches the crash dive depth (normally about 70 metres) you order the u-boat to another depth (higher or lower) then what happens is that the u-boat sits down by the stern at an angle of about 10 degree angle!!! The only way to get the u-boat back onto an even keel is then to order another crash dive and of course let it complete.

Due to the abundance of positive buoyancy that allows the U-Boat to hover like a Humming Bird this "feature" was not seen by the player. It would have however made the u-boat sink or sink more severely when the stern of the u-boat was flooding but this is something that the player would have expected and hard to tell the difference between flooding occurances.

So if you order a crash dive ensure that you let the u-boat go the full distance, you can however change speed & direction without issue.


If you are experiencing the Crash Dive Blues you can remedy the situation by re-ordering the crash dive (even while submerged) and allowing it to go through the full crash dive.

Special Notes...
1. You can change speed after ordering a crash dive without incuring the Crash Dive Blues
2. You can change direction after ordering a crash dive without incuring the Crash Dive Blues

For example, if I order a crash dive and as the u-boat reaches a depth of 15 metres then order silent running and a course change of 180 degrees, as long as I allow the u-boat to level out at the specified crash dive depth, then I will not expereince the Crash Dive Blues.

The Crash Dive Blues! effect does carry over to the next dive. so if I order a crash dive, change depth before it completes and then immediately surface then the next time I dive I will most likly experience the Crash Dive Blues! issue. The way to remove it is to order a crash dive again.

If you are damaged then your crush depth is reduced and that means at depth you may be very slowly recieving damage which will result in flooding that may not be obvious by way of the flooding icon in the vrew management screen.

These are images from my testing of the IXD2 at 1 knot at 200+ metres.

And I always let the crash dive go all it's way down to 70meters. That's why I'm a bit confused here.

One other thing came to my mind.. when ever I start a dive I dont click right away the desired depth, but I start it by pressing the normal dive button. And after that I choose the depth. By using that method should I press the Level The Boat button also when at desired depth? Could that be the problem?

When surfaced I have always just ordered a depth, used the crash dive or persicope orders.

While submerged if I have ordered a change of depth and change my mind I have used the level the u-boat order, i.e. 'a' button with no side effects.
