I get the right Range. But when i try to get the AOB i get Problems.

I count 54 Optical Units Lenghts. Problem is that the Ring on the Optical Lenghts only counts to 40. What am i doing wrong? How should i cope with that Problem?

Yes, I see in the WOS thread that you got a fix

THEBERBSTER link shows what to do if ship is to large for the scope view.

If the target is too big to fit in the RAOBF at x6 zoom we use x1.5 zoom.
6 / 1.5 = 4
So if clicks are counted in 1.5 zoom you must X by 4.
Or you can set your clicks to the bottom right black marker (note: if you put 10click at bottom right marker - the top black marker shows this number X 4)

If your click go over 50 (no 50 on wheel) the numbers continue.
so 0.5 becomes 50
next mark up is 55
next mark up is 60 and so on.

I don't use RAOBF for AoB determination, most of the time I use mk1 "eye balls", but if I remember correctly, it doesn't matter how many marks you have counted until you are able to find correct ratio between ships length and height...Something like that...

Hi guys,

Please help. 2 hours and i can't hit anything in the RAOBF practice tutorial.

The learning curve is huge (not played SH5 before, so finally I got an afternoon and thought I would get stuck in).

I have followed the tutorial, I think, to the letter.

I have the firing solution

Target: Hog
Bearing: 221
Range: 1080
Speed: 0
AOB: 51

After entering this data I load the torpedo and press fire. Estimated impact 1:10, but it never hits.

I look on the map and can see the torpedo launch and turn left, but with the mod there's no enemy ship displayed on the map so I can't tell by how much the torpedo misses the target.

Any ideas what I'm doing wrong?

Are you sure, you have right solution for your target?
Don't use map, use external camera if you want to see your torpedo track.

Firing at this kind of angle is very disadvantageous, fire at 90.

Use rule of 1:1 - if you have target at 51 aob at bearing 221, it will have 90 aob exactly at 221+(90-51)=260, or was at 182 if it's at opposite direction.

And remember most important is to have absolutely prefect speed of target. You can have +- 5 degrees wrong aob if you have it's speed perfectly and you fire at 90 aob.

At 51 aob you need much more prefect solution

And try to be turned as straight to your point of impact as you can (to not need torpedo to turn at its track) if torpedo turns, you need to have precise distance, otherwise if you are straight to point of impact and you fire at 90 aob, you don't even need to input any distance at all because of Pythagoras theory.

Ok thanks it seems I just made an inexperienced assumption that firing with parameters taken from the RAOBF would be enough to hit the stationary target, with no other requirements.

Question: with the scenario I gave, the torpedo must make a significant turn to the target which from the sub is bearing 221. Does the gyro take into account the arc that the torpedo must turn? Because the moment the torp leaves the sub, and makes the turn, the final torpedo heading won't be 221.

I'll try turning the sub to target and see if I do any better.

Do you fire torpedo from bow or stern?

Post #160 Using The RAOBF Wheel In Silent Hunter 5

[OldCoder]

Hi, thanks I played a bit of sh3 some years back but mostly it was Hunter Killer if anyone remembers that and Silent Service 1 & 2.

Yes I fired from the bow, which I realise was sub-optimal... but still I'm curious to learn if there's some calculation that would hit the target, or if it is just not possible with those angles?

[palmic]

Hmm I'm not sure if it was even possible to force torpedo turn such a track angle, but from what i know you would be real ace to hit such target

Try easier shot and you have to be successful

Thanks for your help. I've mostly figure it out, for stationary targets at least and hit a couple in that tutorial.

Then I switched to the Torp practice one, with one target moving from west to east. Changed the time to day so I could use the external cam more easily to see what's going on. I spent about an hour on that, couldn't quite damage the ship, the closest I got to hitting were torpedos almost skimming the bow and stern separately, missed by a couple of metres each way. Then finally I hit the ship... only to have the torpedo bounce off it, arggg! Anyway, getting closer.

RAOBF is very intuitive once you get comfortable with it. I just attacked convoy at noon from about 9km by slow eels to have time to escape, 2/3 hit targets. I play at max realism without external camera, so i don't know which.
I can only hear torpedoes at hydrophone station
