SH5 Realism Video Tutorial

[ddrgn]

No more avi downloads, see the youtube video. For those that really want the avi versions pm me and I will give the link to download.

For future video I plan on showing a convoy attack using the same methods.

For convenience and on-line viewing here is the youtube video links (obviously quality is better with download):

part 1: http://www.youtube.com/watch?v=lmI62YjaZt0 (480p)
part 2: http://www.youtube.com/watch?v=MIUtdsV-XVs (480p)

In this two part 16 minute video I show how to manually chart the targets course, speed, range and angle on the bow, all without using map contacts or the auto TDC.

I start at a distance 6500 meters from the intended target and make real time adjustments to the TDC and show how to chart speed and course based on visual readings.

I whipped this up rather quick and may have left some points out, if your not clear on anything please let me know.

For visual purposes I am playing with the external cam on.

223 mb, 2 AVI files packed in RAR format.

I am using Advanced Shift Keys 1.6 in this tutorial but any Command Key mod should work.

This is not intended to be taken as the only way to play, calculate solutions etc... I only wish to show how I play and if someone learns from my style of play than I have accomplished my goal with this video.

Enjoy and Happy Hunting!

EDIT: Never try and control a type 7C under the influence of German liqueur. Course was actually 275 degrees. Read further down for the adjusted math.

Nice video. Pretty epic AOB calculations. :)

You could have used the 3 min 15 second rule though. Mark points from 0 time to 3 min 15 seconds. Measure the distance in meters and divide by 100 to get speed in knots.

So instead of 850 / 180 = 4.7 * 2 = 9ish you could just do 900m / 100 = 9 kts. :)

One thing I'd like to see is a bad weather or night manual targeting video. Every tutorial is always in perfect weather where you can see things for nautical miles, but every attack I make is in crap weather and I can never see anything! :)

Indeed, Calculator is just fun to use and for some reason knowing the conversion from meters per second to knots is just too much fun to pass up ;]

Calm weather bad weather, the math is the same and attack methods don't change.

Next video I do, I will show single boat convoy attack in bad weather, same methods. More detailed too, with less alcohol in the gutt.

[rededge]

Cool vids mate, just not too impressed you were drunk in charge of your boat!
:haha:

[funkster319]

Thanks - Nice vid and funny too :DL

Can you explain a bit more about the "Target Course +Rel Bearing - 180 = AOB" Rule? Where does the 180 come from? I have been working out true bearing (Rel Bearing - Sub Course) then using an AOB Banjo but this method seems far faster.

Oh and shouldnt the plots be based on true bearing rather than relative.

Sorry for the noob questions.

[Decoman]

Thanks a bunch! :DL I'll be off to get that shift key mod.

[gutted]

LOL the target was not doing 95 degrees.

95 degrees is easterly... not westerly.


Also, if you are pretty much perpindicular and looking "right", you can just do 90 - current bearing to get his AOB.

[ddrgn]

Shows how I get the math....

LOL Gutted, any small little mistakes I can chalk up too 8 shots of Jager

Course was indeed 275

Math should have been TC (275) + TTB (25) -180 = 120

Keep in mind tho that it was backwards math but adjusting the AOB to the right side of view compensated for that mistake.

[funkster319]

I dont understand the AOB calculation? Is this correct?

Target Course (Which I believe was actually 275 and not 95?) + Relative bearing to your sub (25) - 180degrees? = AOB?

Can someone explain this to me as it seems a far easier way to calulate AOB than what I am currently doing.

[funkster319]

Ah beat me to it - Thanks Mate :DL

[gutted]

Indeed. I played once after coming home from a night out... and i fell asleep at the desk.

[funkster319]

From your post elsewhere:
So its Target True Bearing + (plus) Ships Course - (minus) 180 = AOB Which in our case is:

50 + 270 - 180 = 140 AOB

Now adjust the range and confirm the speed.



Is the Target bearing (heading) relative to sub or to True North? Is there another step if your sub is not a 0degrees or is your sub heading irrelavent?

Now if your True Target Bearing is 350°, you would simply minus 10 from the formula as so:

10 - 270 - 180 = 80 AOB

? Is this the only time the formula would change?

Sorry for all the dumb questions, I just havent seen this method before.

[ddrgn]

Relative Target Bearing or True Target Bearing (TTB) is relative to true North.

So if your Targets bearing via your scope is 45 degrees and your course is 350 degrees his TTB is 35 degrees. In this case lets say his course is 225 degrees

When you see him on the left side of your scope at 350 degrees you do the math like this:

225 - 35 - 180 = 10 degrees AOB

If his TTB is 15 degrees and his course is 300 then like this:

300 + 15 - 180 = 135 degrees

You either add or subtract depending on which side of your boat he is on.

Good luck doing this with Sonar only :O: Hopefull after Patch 1.2 we'll have a similar system to SH4 on the Sonar Station, that worked really well.

By the way, mine's a Crown Royal :D

[ddrgn]

Sonar only is kind of useless without a properly working hydrophone. Would you like to see a tutorial showing how I play TMO using only my ears?

[gutted]

If you really want to do the math with a calculator.......


(Your Course - Target Course) - 180 = Angle On Bow at your nose.

If it's negative it's Port, if its positive its starboard. After you get the AOB at your nose.. just add or subtract the number of degrees you are looking to the side. Looking left.. subtract. Looking right... add.


.ie
Target Course 40
Ownship Course 290.

(290-40) - 180 = 70 AOB at your nose.

If looking left 30 degrees... subtract 30. .ie 40AOB Starboard.
If looking right 30 degrees.. add 30.. ie 100AOB Starboard.



example 2:

Target course 40
Ownship Couse 150

(150 - 40) - 180 = -70 AOB (remember negative is port)

If looking left 30 degrees... subtract 30 .ie -100 AOB Port
if Looking right 30 degrees... add 30. .ie -40 AOB Port.

just ignore the negative signs on the AOB.




That said... doing this with a calculator is totally unecessary. You can just do it by eye once you've practiced it enough.

Many ways to get the math, to each his own.... Hopefully some other guys learn a few things from this post, a few new skills and ways to do things, adding to their own style of play.

[gutted]

Yup.

But really... all you need to do is find the AOB at your nose. Put your scope at 0 and enter that AOB, and you are done. :D

So it just condenses down to:
(Your Course - his Course)- 180 = AOB at nose. (Negative is Port).

Put scope at 0, enter the aOB.. then slew the scope to the target.... and done.

[funkster319]

Relative Target Bearing or True Target Bearing (TTB) is relative to true North.

So if your Targets bearing via your scope is 45 degrees and your course is 350 degrees his TTB is 35 degrees. In this case lets say his course is 225 degrees

When you see him on the left side of your scope at 350 degrees you do the math like this:

225 - 35 - 180 = 10 degrees AOB

If his TTB is 15 degrees and his course is 300 then like this:

300 + 15 - 180 = 135 degrees

You either add or subtract depending on which side of your boat he is on.

Aw Thanks Mate

So just to confirm -

1) I should be marking his postion on map with True Bearing calculations (To North) So therefore I will get his True bearing when I use ruler to join the marks (Good -This is what I have done in past) :DL

True Bearing = My Course + Scope Bearing (target)*
*If over 360 then minus 180 to final calculation.

2) If Sub is on the targets port side (Left) then (TTB+ (plus) RB-180 = AOB)
-or-
If Sub is on the targets starboard (Right) then (TTB - minus) RB-180 = AOB)

3) I also assume that if you alter course then you must recalculate the whole solution?

Correct?

Thanks so much for this as it will really save me so much time - No more AOB wheels etc :rock:

[gutted]

(Note: to my posts) Sometimes you may have to add the 180 instead of subtract it to account for wrapping. .ie Your course is smaller than his course.

Just use your judgement.

Yep change course, solution changes this is where doing math in your head on the fly like our friend Gutted has mentioned, will benefit you greatly.

[kylania]

I'd watched the HydroHunting (http://www.subsim.com/radioroom/showthread.php?t=154461) video from SH3 and it was pretty epic.

I dont do any math in my head.

I just look at the ship and match what i see on the AOB entry dial. Thats it. I used to do the math, but i realized it was pointless if you are firing from ideal positions.

Your right AOB can be done really easy by eye and doesn't need to be exact by any means.

Amazing that vid came out in 2009, I was doing hydrohunting via OLC 100% realism long before that. Should have made a vid back in 07 ;]

[ddrgn]

FYI - The mods I had installed during the video.

Most of the overwrites are just readme.txt files.

Ok this seems to be working out really good :DL hooray

However one quick question what do I do when I get in the follwing situation?

My Course 20 , Target course based on True Bearings plotted = 285 (From ruler)

Therfore (20-285) -180= -445!!

Do I Change the solution to (20-285)+180= -85 ????

Any help appreciated as this seems to work very well and quickly :yeah:

-85 = AOB at nose: 85° port. Seems right to me.

Yep, LOS!

[Bilge_Rat]

very nice video, good work.

[funkster319]

:DYep, LOS!

Great this - AOB off nose is such a great and fast method. Also getting excellent accurancy.

Superb stuff guys, thank you both so much (DDRGN and Gutted :salute:)

Cant wait for the Convoy Vid :DL

Hey, ddgrn!! My computer is down, has been and will be for the forseeable future. :cry: I am on a small laptop. Haven't play SH5. Is it from the German side? I watched your two videos on Youtube, and I thought they very good even though I haven't played. Nice work. :up: I wonder if I will play SH5 or stick with SH4 and TMO1.9?

Hey buddy! TMO 1.9 is nicely polished I can say, very nice work, its very immerse and if that was the last of the SH series, well, TMO would have been a nice way to go out.

Working with SH5 now, few tweaks few mods, after that its not as bad as some would think ;]

[I'm goin' down]

I want to express my appreciation for you work on the Easy Aob mod in SH4. It turned the corner for my boat, and I finally understood manual targeting after using it. Shortly thereafter, gutted unveiled the Solution Solver. After a couple of days trying to figure it out, I was cartwheeling around the room, stopping just long enough to sink ships at long range and at steep angles. Two incredible, game changing pieces of work that reflect great knowledge and application of the underlying concepts of manual targeting using the TDC. (My other favorite is MoBo. Aaronblood is brilliant in my opinion [alternatively, I am dumber than most.])

Keep up your good works, as some of us less technologically oriented skippers (I am being nice to myself with that description) really appreciate your contributions, and when I see your posts I am always wondering what new idea/technique/method you are bringing to the table.
I am off to find that great screen shot someone posted in SH4 of a periscope view of a depth charge obstructing a skipper's view just before his boat was sunk. It is my all time favorite.

[ddrgn]

Geez, send the link my way would love to see that! ;] Thanks for the fine comments, glad AOB mod worked out as well as it did.

[Westbroek]

Great videos, thanks for the nice visual demo (and the laughs). I appreciate you keeping the booze thematically compliant with the game as well. :up:

[captainprid]

Superb video for those of us who do not usually use 100% realism, mainly because we don't know how!!

Thank you very much, hope to see more :salute:

Great Vids, I love to read but the Vids just make it so much easier to understand..Great work..:rock::yeah:
