Manual TDC without map markers?

[Jaskor88]

How do I do targeting without map markers, do I just make markings on the map somewhere or what? There is Stoianms manual targeting tutorial but in it sub is shown on the map. Might be I am just being stupid

I'm just getting used to the idea myself but getting better at it. Still having a good bit of difficulty doing accurate plots while moving. It is a serious challenge and certainly amps up the game, but it feels really great when it all comes together and you sink one.

Any point on the map will work because you are only working with the relationship between you and the target.

Jaskor,

For Manual Targeting without Map help.... you need to find your targets speed and course manually first. you can do this different ways....but the basics you need to know are: 1. own ship course and speed. 2. bearing, distance of target at time xxxx 3. 2nd bearing, distance of target at some time interval later 4. perfered that you take multipule bearing, distances of the target at the same time interval to reduce error (I take at least 4 readings at a 3 min and 15 second interval).

Things to remember...you need to adjust for your course and speed...so plot your course and speed. aka say I'm traveling at 6 knots heading on a course of 270. I would draw a line on a course of 270. mark a random start point and then mark the distance travelled at each reading (of the target). So every 3 mins and 15 seconds your Uboat travels a distance in meters equal to your speed in knots x 100. So in my kind of math that means if i'm going 6 knots....3mins + 15 secs later I've travelled 600 meters. Confused yet?? hehe So every 600 meters along my course line of 270 I put an Mark (X). I usally have 4 readings so there are 4 marks on my course line.

Sooo now you have to plot those readings from each mark you made on the course line. use the protractor function to figure the angle (a target with a Relative Bearing of 345 is 15 degrees Port (left) of your bow (nose, course). So draw an angle of 15 degrees Left of your nose and extend the arrow out. Use the ruler tool to draw a line along that line of bearing to the distance of the first reading. at that distance place another mark. Now repeat for every reading that you did. now draw a line to connect the X's your plotted. the distance between each X represents target speed....so if distance is 1500 meters between each X, the target is travelling 15 knots...and so on. the True Course of the target is represented by the line connecting the X's.

Thats manual target speed and course in a nut shell...if this wasn't what you were looking for....sorry about that. could put up a picture later if it helps.

P.S. i use the Fast 90 method of targeting after I have this info....aka I sail a course perpendicular to the target to make the AOB 90 degrees at impact.

Nice writeup!

Funny, I've used the 3:15 rule for ages in SH3 but I never though to apply it to tracking my own ships position with Real Navigation. I used a calculator sitting next to my laptop to do the conversions.

Yeah I thought it was like this. My brains just didn't work and thanks finchOU this clarified things more

I usually try to be at 0 knots when I start plotting so I don't have to worry about my own movements messing up my calculations! Not always possible of course and I too had never thought of simply using the 3.15 rule to make it much easier.

I do find the nomograph very helpful for quickly working out speed etc and distances covered in real nav.

Nice thread, especially this post from finchOU

I have started to use Real Navigation with 96% realism ( external camera is the only option I leave unchecked ), so this is helpful.
