Magnetic disturbings in the English Channel?

[Paajtor]

I'm currently working my way through the English Channel, and I noticed that my compasses (HUD, CommandRoom, and Bridge) don't show the correct angle.
I have verified the angle, by comparing to the NorthernStar...my compasses are off-set by about 90degr.

Is there some form of magnetic disturbance modelled in the English Channel (like rocks with a high % or iron, or something)?
If so, that would be cool, btw.

I am using IUB1.02 with Pascal's Dials enabled.

Uboat hulls on the bottom? :hmm:

Point your boat to the north star. Everything should then show 000 degrees, if the astronomical model is right. Otherwise, go to the map, zoom all the way in, place your boat on a meridian and check.

Remember that every single bearing thing in the game, like the UZO, the scope, EVERYTHING, except for the outer ring of the gyrocompass, is in relative bearing. IE, the angle from the bow of the boat, not the angle from the meridian.

Beside, the compass in the game is a gyro. It's not affected by magnetic effects...

And magnetic variation of 90 degree is just plain crazy.

Its called magnetic deviation an annoyance to navigators everywhere.

Although I sincerly doubt this is modeled into the game.

[Paajtor]

Yes, I doubt that too, allthough it would be great.

And yes, I am talking about the outer ring of the compass.
Kinda weird...I am starting to suspect the game's saving-system. :hmm:
It was ok before.

I will try a single-mission this evening, and see how it looks...after that, I will load my career, but without exiting SH3 first.

Thx for your suggestions.

True that... But hardly a 90 degree deviation!...

Indeed my bad it was a shoot from the hip reply

But on second thought it may very well be modeled into the game as Flight simulator has had it for years. The alogarithims for this and the "star charts" are pretty much public domain.

It would be interisting to take a north shot near Gibraltor then sail over toward say Florida take another north shot and compare the two.

Anyone got a lot of time on their hands ?? heh.

The "Bermunda Triangle"?

[Etienne]

VARIATION is due to the irregularity of the Earth's magnetic field, the offset of the magnetic poles and local anomalies.

DEVIATION is due to the ship's own magnetism, induced or permanent.

Yeah, I'm pedantic :-D

And neither are modeled in the game, since the game doesn't have a magnetic compass, AFAIK.

[Paajtor]

All compasses seem "fixed" now.

As I said, after 1st playing a single mission (all was ok), I fired up my career...everything was back to normal.
I used the same saved-game that I was running the day before.

I suspect the saving-system...I've seen odd things happening, especially if you hit Save&Exit, then Save, and then Continue mission (after saving succesfully).
At least in career-mode, I'm going to Save&Exit-to-menu from now on.

isnt that a problem if you installed pascals Dials wrong

[Paajtor]

Nope...it was working ok before (and it's ok now again).

I enabled Pascal's Dials using JSGME (it comes with IUB1.02 as an option).

when portugal discovered hte malorca islands I think its called , it wa a bastardization of the portuguese word for crazy because of the way their instruments would go nuts around there. what does this have to do with the price of tea in china, dunno :rotfl:
