[TEC] Athwartships rolling . How can i reduce the sub athwartships movement and what are the consequences if i do .

Sweet! Word of the Day!

Basically your boat never moves in stock right? Personally I use ddrgn's UHS mod which makes it rock a bunch and I love it. Pretty sure he detailed what to change to make it rock like that in the thread.

My english is bad so sometimes I don't understand the technical terms.
But I read this thread and some interesting points there:

Don't feel bad, I speak English as a first language and had no idea that word existed!

[Echolot]

Google translate mean this is "Querschiffs" in german.
Maybe it could be translated back to english. :o

@ Echolot : :rotfl2:

Didn't know that word either. :88) :ping:

OW! OW! OW!

Oh no!

Just curious.... but in these ship data files, are there any references to a variable or characteristic called metacenter or metacentric height?

In RL, metacentric height (the distance between the metacenter - the intersection of a vertical line drawn through a vessel's displaced center of buoyancy (such as when heeled) - and the center of gravity) is the characteristic that defines a vessel's stability. Transverse (the actual term the OP was looking for I think) metacentric height determines lateral or roll stability, while longitudinal metacentric height determines pitch (fore and aft motion) stability.

The term "athwartship", BTW, typically refers to the placement or orientation of an object in, on, or around a vessel.

I know its a silly question but what are athwartships?:06::06:

[Madox58]

Athwartships, as I understand, is a left to right type thing?
A row boats seats are Athwartships, correct?
To reduce or increase this motion,
the center of gravity needs moved.
Up to increase.
Down to decrease.
It's in the sim file.
You may also adjust the drag settings in the sim.
Now I have a head ache.
:nope:
:har:

[MLF]

Athwartships = left to right, side to side, or Port to Starboard and vice versa.

Fore and Aft = from the front (forecastle) of a ship to the back (poop).

Now lets try "Monkey Island":). Any guesses?

MLF

[Madox58]

Monkey Island is at the Toledo Zoo, right?
:haha:

[Echolot]

"Transverse" :yep: was exactly what google translate this one "Querschiffs".

I also tried editing some files to change the behavour of the subs in water but without complete satisfaction. Was better then but it's bad with the drm thing and thousands of restarts of the game. I had tweaked the sim.cfg too, but then I read about some possible unwanted side effects and think this one is for experts. I'm better with graphics editing. I can't use the UHS because I need to start a new career and this is odd while modding everyday. If anyone have done a tweak for this (maybe only seaparameters und sim.cfg to activate whenever I want), plz let me know. It's one of the most needed mods here. I found the sobers wave mechanics not too bad, maybe a little slow, what can be changed. With Improved Pitch and Roll by Hansolo i have problems in multiplayer mode. At the moment I use Hansolos 1.1 w/o the submarine folder.

Greez,

Most settings for Center of Gravity (Up and Down)
And Forward rear center (Front to back)
are based on the center of the object when imported to the Game.
Moveing the CG up will produce greater side to side motions.
The front to rear?
On importing Units from SH3 or SH4, it needs moved just a small amount.
And I mean a VERY small amount!
From .5 to like .497
Don't ask me why.
It just does.

There is also drag in many areas that may need twiddled with.
I'll admit, SH5 is a crash cart of WTF?
But if you look long enuff and hard enuff?
It's all easy to fix.

You just have to put away the fear of the unknown and
make it known.
I probably have a flat forehead by now from smackeing it
and sounding like Homer Simpson!
DOH!!
:har:

Ups, I remember the hours or days i'm over the VIIC in SHIII with waterstream and reflection controllers like TDW have with the sub flags reflections in SH5.
I was near going out through the window. :damn:

I tried changing this but in SH5 any effect was not really noticeable. In SH3 I got the sub rolling slowly (actually managed to capsize it:doh:) just by making small adjustments to the gc_height (centre of gravity height).

[Madox58]

I did notice SH5 is wierd in this area.
I'm not sure what is going on at this point.
It may need finer adjustments then SH3 or SH4 used.
And I mean adjusting by .001 and such.
SH3 and SH4 .01 changes were OK
SH5 does not like that amount.

We use the word athwartships while stevedoring ships . Thats how i know it . You are correct in saying that is refers to placement of an object in or on a ship /boat .

I think that is where U-Boat Historical Specifications MOD made changes for Pitching Fore/Aft. Most likely have Roll Port/Stbd controls there as well.

I want to know how to get the Bow on the Type-VIIC/41 up out of the water. When I am Surfaced underway (12 Knts) my bow dives under the water all the time, plowing through waves while the Stern rarely goes underwater. Exact opposite of what I would expect to happen. The bow is about 0.5-1 meter to low in the water.

I also want more Sea Spray when waves are breaking on the Conning Tower... Currently waves rarely make a splash, even when going over the Tower.

I think this can be changed in goblin (bow/deck/conning fx but which files ?

Yes - I changed gc_height and even tried LR Drag but did not notice any difference in movement -still had the same low centre of gravity type movement - quick short rolls, duck on a pond type thing. What I would like to see would be long slow rolls, with water splashing over when the roll gets out of synch with the waves. :yep:

Hi:

This mod changes sub pitch, maybe is useful:

The SH3_to_SH5_Sub_Physics (http://www.subsim.com/radioroom/downloads.php?do=file&id=1792) does Roll, Pitch, Bobbing and slightly positive bouyancy.
