Calculating Range in Rough Weather

[CaptainNemo12]

Recently, I almost lost all faith in the 3 min 15 sec method...

The problem is, range always plays a role in determining speed, and calculating range during rough weather conditions can be a real pain in the ass if you know what I mean. To maximize realism, I have the stabilize view turned off, with the boat rising and falling almost constantly, it's almost impossible to get an accurate reading! Plus, by the time I do get the stadimeter to line up with the waterline, a lot of time has just been wasted! Is there another method out there that can be used to calculate speed without trying to figure out range?

Thanks.

They usually didn't make attacks in extremely rough weather. It was even a bigger pain in real life.

Other than that, I don't know what to say.

I use different tacticks for calculate speed.

you will need a small exp. in mathematic

Thise how i do it

first you need to know the leight of the ship.

Lets take a medium cargo for example - her leight is 140.5 meters
now use our vertical line in uzo our periscop view.
Symply start to count in for how much time the ship will pass thise line without moving it (i` am sorry English is not my mother language and its very difficult for me to explaine properly).
Now
Lets the matematic begin
Lets say that the medium cargo pass the line in 55 sec
now we have 2 infos
140.5 (the leight of the ship)
and 55 sec
now for the fune part
140.5 to divide 55 = aprox 2.554545 ok - thise is miters in sec
Now lets convert thise in knots
2.554545 To increase 1.946 = 4.97 knots

Thise is the speed of your target. Sorry again for my very pure English but if some one found my metod interesting i can make a small tutorial with screenshots

Dimitrius, don't apologize for your English. It's actually very good. And considering English is one of the most difficult, mish-moshed, cobbled language out there, I've a great deal of respect for anyone that manages as well as you do with it when it's not their native birth language. Heck, I blush to say there are Murikans who aren't as literate as you are.

Unfortunatlely, Dimitrius07's technique only works when you are 90 degrees from the target.

I use the "Assisted Plotting Mod". The target is on the map only if my cursor is over it. So I can still be surprised by DD's I may not have spotted. Just mark on the plot where the target is and start a watch. 1, 2, 3, or 3:15 later mark again (whatever time you like) and measure. Easy math. Now you have the speed.

I like this "Assisted Plotting Mod" in NYGM because it is a fine balance of having me do work and still have help from a "crew".

Lanzfeld lets say that my technique will be more accurate when the ship is on 90 degrees - but its not unposible to calculate speed when the ship in lets say 75 or 80 degree.

Dont forget that thise is a quick metod .

Is that correct? I can't prove it mathematically, but as a thought experiment if you are not at 90 degrees the ship appears truncated, however it will take a longer time to traverse your crosshairs so maybe (?) it works out the same. Can't check this as my computer is dead and I'm doing this at work!

Where did 1.946 come from, mate?

I found thise information in some Russian websait, not long ago , and i think it sems to be correct :hmm:

meters per seccond To increase 1.946 = knots.

Thanx, mate, but how could i use it in calculating..? Shall i first take the meters pr seconds and add or divide with this 1.946 , or...?
I am a little stupid on this, sorry mate..
Edit: My bad, i have to multiply m/s with 1.946 to get knots...
Sorry mate!!

I have a small "cheat" to solve that problem. Just use Pause and TC x1 until you line up the stadimer with the waterline, then, with the game in Pause you still can mesaure the height of the mast.
