Stadimeter bugged

can someone confirm that stadimeter works accurate with that addon?

Dude this is subsim!

Erm, I just did...

The use of the Statimeter in the game is nonsense because measurement of the height from sea surface to the top of the mast never provide accurate results, because an empty tanker for example has a shallower draft than a full tanker and thus also the height to the top of the mast is differently with the same type of vessels.

During my time in the navy we measured the mast height from his root to the top and not from sea level because only this value is static.

Good point, I'd never actually thought of that!

How would the real U-boot captains cope with this problem, I wonder.

yes its true. The mast height is taken from root to top. Ive been saying this during sh3 times already. But on the other hand its easier to messure from sea level and there is always same draft regardless of payload for each ship anyway. If you want realism someone make a stadimeter mod that works from root to top.

@Shiplord

Great post, that never occured to me but the reasoning is obvious, perhaps theDarkWraith could make this change in his multiple UI mod the ship config files?

Because that would be a drastic change that would satisfy a small handful of people and would probably be incompatible with other ship packs and completely at odds with stock features?

That's the problem with the stadimeter in the Silent Hunter series, it's broken by design since SHIII

Actually the use of the stadimeter in the game (SH3/4/5) is right on... for that time period. Unless the Germans did it differently than everyone else (I'll be happy to stand corrected if they did), mast head height was always taken from the waterline.

See section 4J of the Periscope manual on line at maritime.org.

As far as I know, there were no stadimeter on the German subs. The distance were simply estimated because it plays no role in the method the Germans used. They use for the solution, a collection of firing tables and these tables are based on the mathematical formulas of the Thales' theorem also called intercept theorem. No matter how far a target is away, if it is still within the range of a torpedo, the distance is not important. The correction angle is always the same no matter how far away the target is, if the speed and heading of the target don't change.

The link HERE seems to suggest this is correct. At least for other than early war boats. Apparently the early war boats had stadimeters in the attack scope, but the later binocular optics did not allow the installation of a stadimeter.

BTW, the full link is broken at the moment, which is why I linked to the "quick view".

2008 this table based on Thales' theorem was posted on the Ubisoft forum

I used it in SHIII and it worked nearly perfect

Wow, very interesting! Could you explain a little more how this works ? Thanks a lot !

this is nothing more but a lead angle chart. You still need speed and angle on bow to use that. You dont need range for lead angle calculation but you still need it to find the speed and course of target. You cant estimate everything.
