Re: The Plot

@Antonio Hello Antonio. Thanks for the map. It's difficult (at least for me) to evaluate, as although it contains directions, i.e. azimuths, there is no scale. Also, as the time "window" you associate with it is about eight minutes long, and ships moving at 30 knots or so can move 4000 yards or so d...

Re: The Plot

There has been a lot of discussion here on whether or not "The Plot" is incorrect. Of course it's incorrect. The technology of the time simply did not permit more precision than shown, and -- perhaps more importantly -- it is clear from the full transcript of the Board hearings that it was considere...

Re: The Plot

I think it's important to keep in mind that the various plots and charts used in the Hood inquiry were in a sense of secondary importance insofar as the Inquiry was intended to determine the CAUSE of the ship's loss, not to necessarily reconstruct in great detail the tactical maneuvers that took pla...

General comment

Before concluding with any certainty that the discrepancies and irregularities in the action(s) of 24 May may be ascribed to a 'cover-up', it would, be necessary -- or at least highly desirable -- to show, by actual demonstration, that similar levels of discrepancy and disagreement are not present i...

Re: (more on) Bismarck Steering Gear

Further to my previous link, if that doesn't work, GOOGLE "The Wreck of DKM Bismarck − A Marine Forensics Analysis". It's downloadable in .pdf format and includes several diagrams that might be useful.

Re: Bismarck Steering Gear

Finally remembered one source, which includes a plan, at least of the after part of the steering gear, on page 26.

Re: Bismarck Steering Gear

I was surprised to find how scarce copies of these sorts of drawings are on the internet and in various secondary sources, particularly when one considers how critical the steering arrangements turned out to be in the sinking of Bismarck. That being said, drawings ARE indeed available. A 1:10 scale ...

Re: Bismarck Steering Gear

You have a lot of questions there, but it's possible to tackle them all, albeit briefly. I'll insert brief answers -- recovered from memory -- into your text between asterisks, so please read on.. Were both rudders linked? ***Yes, but they could be worked independently as well.*** Is it an electro h...

Re: Accuracy of Iowa Top Spot optics.

That relative performance of optical vs radar spotting, though the quotes are probably correct (Cdr Morss does not make things up), would certainly be considered atypical for regular day-to-day performance. Even in the 1980s the Iowas habitually used radar spotting for range, optical spotting for de...

Re: The Court Martial for the Denmark Strait

Yes. I think that 0603 is fairly close to correct. Hood blew up at 0600 or so, and Prince of Wales took a fairly heavy pounding during the following few minutes. After rounding the wreck of Hood, P.O.W. was in some ways pretty much a wreck herself, and the decision to disengage, at least temporarily...

Re: The Court Martial for the Denmark Strait

Although I have great respect for Mr. Bonomi's work, I'm afraid I must in this case express some skepticism regarding his fairly recent suggestions that there was some sort of 'cover-up' regarding British tactical activities at the Battle of Denmark Strait. My own observations and opinions are as fo...

Re: The Plot

All of this lengthy discussion has been interesting, but I fear that we may overall be missing the point, that being that the various plots etc. under discussion were intended to support a TECHNICAL rather than a TACTICAL analysis of the action, i.e. they were intended to support an inquiry into the...

Please excuse my ignorance here; as most readers of this forum will know I'm primarily a 'nuts and bolts' guy who tends not to follow tactical discussions in detail. That being said, this particular thread seems to have become a relatively hot one over the past few weeks, and I'd be grateful for a l...
