Gentlemen can we just confirm these "famous" speed trials took place in the Baltic?
Yes we can.
All speed trials took place in the Gulf of Danzig, in 65-meter deep waters off Neukrug, in the Vistula Spit, not far from Pillau (today Baltiysk).
Why?

@José

8,8/4 = 98,8 dm = 9,88 m
Thanks, my mistake.
That gives a mean draft of 9.865 meters which corresponds to a displaced volume of approx. 48,000 m3 = 49,200 mt in seawater.

Re: FYI: meaning of the notation of the draft measurements during Bismarck’s trial runs, fall 1940

Marc, Thank you very much for posting this. So, if I understood that correctly, for the famous speed trial of 29 October, 1940, we have the following data: Draft forward: 8.5 / 4 = 9.85 meters. Draft aft: 8.8 / 4 = 9.80 m meters. Mean draft: 9.825 meters, which corresponds to a displaced volume of a...

Re: Machinery Volume

For Bismarck the volume of the 6 boiler rooms + 3 turbine rooms is 10,250 m3 (9,835 m3 without the cable alley). The turbine rooms alone are 4,660 m3 (4,520 m3 without the cable alley). boiler rooms + turbine rooms: 11,003 m^3 turbine rooms: 4,517 m^3 Marc, I calculated the max. enclosed volume: Ce...

Re: Machinery Volume

I made some rough calculations of machinery and boiler room volumes from Bismarck (from Brower´s) and Richelieu (from Duma´s). The results are: -Bismarck: 10044 m3 -Richelieu: 8363 m3 I have those spaces lenght and helght of KGV (from Burt´s), if anyone has the widths we can add to the comparision....

Re: Some questions about the battle at the Denmark Strait

However I do correct myself, since the turrets are all-over grey as repainted in Kors Fjord on 21st May 1941, there is a strong likelihood the photo was taken during the mission. Sorry, I hadn't seen this. IF you accept that photo #2 was taken during Rheinübung, what action could that be other than...

Re: Some questions about the battle at the Denmark Strait

OK guys let's not begin to divert the conversation.
Your points are taken.

Next question:

Question #4.
Do you agree that the three smoke puffs shown in this photo originate from Bismarck's secondary battery?

YES
NO

Re: Some questions about the battle at the Denmark Strait

Anyway. No. There is no evidence in this still , that it was even taken at the Battle of the Denmark Straits. With no enemy shell splashes there is no evidence it was even taken during a battle. Well, then I guess you could say the same about at least half a dozen other photos taken by Lagemann "du...

I have to say no, I cannot agree, because we have no reliable method of time stamping the images.
Would you say then that the battle film scenes are from an EARLIER period of time than the photo in Question #2 ?
I'm really interested in your opinion.

Re: Some questions about the battle at the Denmark Strait

Dunmunro, I think you see too much.

Anyway, let's move to question #3.
Do you agree that the film sequence of Bismarck firing included in the PG battle film was taken at a later period of time than the photo shown in question #2 ?

YES
NO

Re: Some questions about the battle at the Denmark Strait

Thank you all for your replies and comments. Now, let's move on. I'm attaching a photo below taken from the Prinz Eugen during the battle of the Denmark Strait where we can see that the Bismarck, in the background, has just fired a salvo. We can also see three cartridges from 20.3cm ammunition over ...

I did not research these topics in detail as most of you did, so I don't have an opinion.
