How can i change the Sea handling Qualities of a Ship?

@LtzS_Petersen

Could you explain what the variables you changed relate to?

• gc height center of gravity, I assume
• fr ratio ??
• UD ??
• LR ??

Also, I don't understand the screenshot where the surfaced displacement=0 and draught=0.

BTW, the last version in the video looked much better.
How is the acceleration/deceleration and turning?

[LtzS_Petersen]

fr ratio is the Center of Gravity over the length of the Ship, 0,5 is the Middle, 1 is the Bow. If her Stern is to often under Water i reduced it a little bit. Its like shes hanging on a Hook.
UD- Up-Down drag Coeffizient, if it is smaller, the Ship moved easier.
LR- Left- Right, the same.

But this is more for a later finishing or a single Ship. I found here (anywhere, dont know where, i think i was from Keltos) this, thats more global: ^^

..edit the sim.cfg located in data\cfg
change this:

[Mech]
Waves amplitude=0.2
Waves attenuation=0.75

into this:

[Mech]
Waves amplitude=0.5
Waves attenuation=0.03

But this is for all Ships. I use the SH3 Physics for SH4 Mod to change the sim.cfg and it works fine.
Surface displacement= if its 0, the Mass will taken, if the Draught= 0, the Position of the Ship (if i remember right, above Water) will taken. The Mass of the Ship regulates the Draught. As i wrote before, with a Mass of 500 she sunk like a Stone.

Acceleration, Deceleration and turning looks for me like before. But the Acceleration was unrealistic

Phew, many english Words.

I will make new Trials with the Asashio DD from peabody, if i find bad Weather Conditions.

Thanks for the reply.
I think I get the general idea of what you said, except I don't understand why changing the mass would make it sink.

The reason why I'm interested is I would like to make the subs and ships more realistic. I play the S-class boats a lot, and I notice they plow through the waves effortlessly, barely slowing down at all.

I will try the mod you mentioned. Please post updates on your progress.

Footnote:
It's a bad idea to change the values in sim.cfg as this "ruins" the environment mod settings.
There may also be some unwanted sideeffects like sinking ships in harbours, convoys etc.

Footnote over. Carry on!

[LtzS_Petersen]

I couldnt believe that less Mass let sink her. I think it is more likely the Counter Force thats the Water needed to hold the Ship.

@Jan Kyster: Thats why i used the sim.cfg from the Mod. Any Change is restorable.

Edit: Here is the Link of this Mod from Vickers: http://www.subsim.com/radioroom/down...o=file&id=1433

Hehe, i think he made already some Mods for Destroyer Command.



You can try the normal Mod first, it changes a lot.

Edit2: Asashio Mod DD from peabody:

only changed a little bit, she was better than the Fubuki.
Mass=2365
gc height=the same
fr ratio=0,45
LR=0,55
UD=0,18

[TorpX]

It looks good.

If you wanted to increase drag, so that a ship or sub will slow down faster, what variable would you need to change?

[LtzS_Petersen]

Mmmh, the Typ IX D2 needs 150m from flank to stop (with reverse flank), i think this is quite good, a Destroyer at 30kt needs 250m in real. In Ports there are the Mooring Lines needed, to take any Movement out of the Ship. Unfortunately we have not any. So a little Movement left.

You can try the Submerged drag, but i have never test any Changes there. So write down all Changes.
