[REL] SH5_MataHari's_More_Accuracy_for_TWoS_1.04_Mod

[MataHari]

This whole treck started when I decided to test wether the draft of ladden ships differs from empty ships or not. I tried all 4 Internal Cargo combinations (None, Freight, Ammunition, Fuel) in Test SingleMissions, using the C2_S-B1 Merchant as the reference ship.

I was expecting a lower mast height and deeper draft for heavy ladden ships.

I didn't see any noticeable differences when measuring the mast height.

After removing all the torpedo limitations (mainly the DepthKeepingDeviation value) in the sim file, I didn't see any noticeable differences when firing torpedoes at ships ladden or not.

I repeated the tests for summer/winter on all oceans, and got the same results. The only thing affecting mast height and draft is the state of the sea.

On the other hand, I noticed some differences with the values listed in the Identification Manual.

I was sure the values in the ID Manual were the result of scientific calculations, but why was I getting some variations when measuring them with accurate periscope graticules?

This is how this mod came about: the production of a manual with precise measured values.

Some may say that the manual or the tools shouldn't be too accurate because such was the reality in those days. That's fine with me, I respect that.

But let's say MataHari managed to survive WWI, and got her hands on secret documents concerning Allied ships. Then she made a Nobel Price winner french engineer her lover, and convinced him to create a more accurate optic device for the KriegsMarine. I'm so romantic ...

Thanks Neal. I did as you said. What would we do without you ?

I don't play SH5, so there's not much else I can say.

I miss you guys from the WPL. Those were the good old days. SH2/DC were the best sims.
I tried SHO, and IMHO it's a way to waist money on a regular basis.
Bye for now.

During a set of tests with a large oiler imported from SHIV, I noticed that she was sitting lower on the sea level when she had fuel as internal cargo than when she was empty... but it was long ago, so I could as well be wrong on that.

I also can not confirm this but, due to "bug", some ships during campaign playout will be occasionally spawned with different heights/draughts so accurate mast height data wont be so much useful in these situations.
This is especially true for ships with Draught=0 in their respective sim file where game has to calculate ships draught from 3D objects height (divided by 2) .

I am afraid I must disconfirm this interpretation of the 0 ship draugth setting. It actually means that ship's draugth is taken from model's absolute coordinate in the global space. In other words, the water line will lie where model's y coordinates are equal to 0. If you open any ship model in a 3D editor you will understand at once what I mean

As to why ships having this setting are spawned much lower that they should at times, I have no idea why this is happening. Another bugged feature maybe?

Yeah, that...Whatever... Anyway, it seems that Draught=0 has an effect on this bug...

If you can take ships sailing sometimes at "deck awash" as feature, than why not... It's a bug, but it's somewhat cool IMO...

Well, as I see it, it is a feature if it adds an acceptable level of reandomness to ship draft; it is a bug, or a buggy feature if makes ships to sail deck awash. Anyway I will check again the Kawasaki oiler that I had been working on years ago, since as I remember internal cargo made her to sail realistically lower than when she was sailing on ballast. There might be some magical combination of settings in her sim file making it to happen.
