Can’t remember the source, but I remember seeing it on a periscope diagram. For the life of me, I can’t remember it.

Per Hitman’s research it seems the Germans dropped the stadimeter with integrated RAOBF early in the war in favor of binocular optics. The thinking I guess was that the added spatial awareness made up for it. So the
C/2 Standsehrohr attack scope (ie the one we all know and love) did NOT have that feature.

Some details here: http://www.tvre.org/en/aiming-with-the-periscope

See especially drawing 16.

Simple answer, some boats had it, some didn´t, but they did seem to stop supplying new boats with the device as the war went on.

There was one in Das Boot, you can just make it out during the DD duel! The old man is looking up to see the bearing, and I think his left hand was adjusting the RAOBF.

Correct side for passing buoys
 

Red, right, returning ... everywhere?

You have just discovered IALA System "A" buoyage. Everywhere in the world except the USA and places that the USA has influenced, like Japan, Korea and the Philippines, have the green buoys to starboard as you proceed with the flood tide.

As you are heading into a port then the tide floods towards the port so you pass red buoys on your port side

So, here I am showing a surface attack at night. Surface attacks at night were actually the most common method of attack, at least during the first years when radar was not yet common.
You will notice that you can get quite close to a destroyer that has not been alarmed if it is sufficiently dark

Awesome vid! Just seeing this now!

You should also take a look at the newest video.

What do we do when destroyers start to have radar?

Stay submerged!

I have just released a Video showing how to use the historical Ausdampfverfahren

It helps to hit the target without measuring speed or AOB.
Good for beginners and experienced Kaleuns alike.

Enjoy

Excellent! Always good to see Ausdampfen used. I live and die by this method, albeit for determining target speed while surfaced (ownspeed x sin(bearing) / sin(AOB)). But yeah this as a shooting method is also top notch!

Been getting back to reading KTBs to help me with my Wolfpack campaign and man does Ausdampfen show up a lot. “Fahrt ausgedampft”, “Schussunterlagen durch Ausdampfen” etc etc.

Just read one from Prien where they got the speed wrong due to “wrong engine setting used in Ausdampfen calculation due to intercom transmitter failure”.

Yeah, the more I read up on this stuff, the more surprised I am that so much was simply done by Ausdampfen or by just estimation.

I did videos on Ausdampf- and Auswanderungsverfahren for SH3 years ago but yours is much better quality (it was before I knew what I was doing recording). This captures the spirit of “working with imperfect information” that pretty much defines my approach to targeting. Ditch the rec manual!

Yeah, I just plot their course and head for the 90 degree approach of that course line. Range is not relevant then.

Speed estimate mostly by shadowing at same speed, but after awhile one gets good enough at eyeballing it too.

Big believer in the KISS principle <g>, especially once airpower, radar, etc. come into play.
