@ Bill Jurens,
you asked :
Here we go.I am having trouble deciphering the chart mentioned, i.e. (download/file.php?id=3346). Although the depiction of the British track on this reconstruction appears to be clearly shown, there appear to be five nearly parallel lines relating to the German formation, accompanied by a variety of unexplained (or at least unexplained to me) dimensions.
More explanation of exactly what this plot is attempting to show would be welcome...
The British tracks plotting is perfect being based on Warrand data and David Mearns Hood wreck finding using those data.
Thanking Herr Nillson help, we have properly corrected my old 2005 map with a more precise set of evaluations:
1) Track in BLUE on top is PG at 28 knots by Herr Nillson ( marked Y in red ).
2) Track in RED down below shows PG at 27 knots by Herr Nillson ( marke X in red ).
Those demonstrate that Prinz Eugen was not running neither at 27 knots precisely ( will end up being too close to PoW at 06:00 ) or at 28 knots ( will end up being too far away at 06:00 ), but in between those 2 speed, more close to 28 than to 27 knots.
3) In order to match the 15.000 meter distance at 06:00 from PoW and correctly draw the Prinz Eugen track I have added the thick BLUE line I have marked V in red, that is resulting being very close to my old 2005 original track but now is very precisely calculated, and it is closer to PoW than before on my old 2005 map version.
4) To demonstrate that the Bismarck cannot be the warship identified at 05:37 on bearing 334°T from PoW I have added on top of it a VIOLET thick line starting on bearing 330° T at 06:00 and back 23 minutes at the same new speed of PG ( around 27, 8 knots ) and it will immediately result that will end up at 337°T bearing from PoW at 05:37 and consequently she cannot be the warship identified initially from PoW at first sight at 05:37.
Now we can more precisely set the milestone new points 1, 2, 3 and 4 and move ahead, ... hopefully.
