“He was the most prodigious personification of all human inferiorities. He was an utterly incapable, unadapted, irresponsible, psychopathic personality, full of empty, infantile fantasies, but cursed with the keen intuition of a rat or a guttersnipe. He represented the shadow, the inferior part of everybody’s personality, in an overwhelming degree, and this was another reason why they fell for him.”

If I understand your remarks, manual steering was executed by turning the rudders toward one another, thus inhibiting the channeling of water under the ship, between the inboard screws and creating a giant drag brake.
These are really great pictures posted by Dreadnought but a question arises "how did the rudders keep from damaging themselves " ( collision wise ) Is there that much radius clearance ? It does not appear so in Dread's post.

I think it was the Constellation that was the only ship in Dry Dock 1 I could walk under standing erect as they used double blocks because of her beam. The dock walls were slanted and double blocks provided a couple of more inches of space between the ship and dry dock.Able to leap tall tales in a single groan.

Paravanes were a device used for minesweeping, Depending upon which navy you look at during WWII they all had different arrays including even the Bismark. Normally it wouldn't be a BB's job to do this but they were equiped for it none the less just incase. Normally it would fall to minesweepers and small craft.
Paravane (please excuse the spelling)
A chain or heavy wire takes a towpoint for the paravanes down the ship's bow to the forefoot and the vane flies through the water, with its tow-wire going back from the bow at maybe 30-35 deg to the centreline. The tow wire is let out maybe 40-50m, so the paravanes fly parallel to the ship, one each side. If a mine's mooring wire strikes the tow wire it is shouldered aside by the tow-wire, pushing the mooring wire and mine further away from the ship, until it hits a cutting blade close to the paravane. With the wire cut the buoyant mine pops up to the surface, and if no sharpshooter can hit a horn, their rifle shots hole the casing and the mine harmlessly sinks to the bottom.
This is a picture of Bismarks paravane array.Attached FilesLast edited by Dreadnought; 14 Jan 10,, 15:20.Fortitude.....The strength to persist...The courage to endure.

Ahhh-ha! So basically two of those 'floaters' shall we say, are dropped over each side and are spread out by the ships motion to 35 degree angles where they snag and force moored or floating mines away from the hull.
I made a crude drawing. The paravane wires are in red and the actual 'floaters' are in blue. Would this be right?
