Re: Titanic tourist submersible goes missing with search under way
Hello All, As those of us who have worked on ships well know, the Sea makes no allowances, accepts no excuses, and takes no prisoners. It is one of the last places where the individual can be truly free, and that freedom includes the ability to make bad choices and suffer the consequences. Even the ...

Re: Radio Finger Printing (RFP)
Hi Fatboy, This is a very interesting method of regularizing something which was previously more instinctive. Thanks for posting this. Morse key telegraphists had from the earliest days discovered they could recognise other operators by their "fist". That is the idiosyncratic way they actu...

Re: Titanic tourist submersible goes missing with search under way
Hi Marcelo, What I saw was just a slice out of the video you posted. Very comprehensive. Wikipedia has pulled together a site including the serious misgivings former employees and professional bodies have had about the safety of the vessel. en.wikipedia.org/wiki/2023_Titan_submersible_incident Compa...

Re: Hypothetical: The British detect Bismarck with a ship-borne Walrus at 0900 on 25 May 1941.
Hi Michael L, I'm afraid I don't see it your way, but then we don't have to agree, do we? Loading the hypothesis by only allowing the tinclad Repulse and KGV with her hidden armament issues to engage Bismarck is giving Lütjens too much of a chance. Looking at Duncan's map PoW is actually closer to B...

Hi Michael L I think Court Martial(s) would be the subject of a separate Post - if it hasn't already been done. Have you searched and read by far the longest ever thread here? Yes it's been done. Done to Death. :cool: I think if Tovey had considered "run out of fuel" to be an actual bindin...

Re: Titanic tourist submersible goes missing with search under way
Hello All, Having seen a video widely available on the web, this submersible seems IMHO to be an amateurish bodge-job, with only the pressure hull of professional standards. It uses a Playstation controller to run its internal systems. :shock: Looking at the sparse external fittings it seems unlikel...

Re: Hypothetical: The British detect Bismarck with a ship-borne Walrus at 0900 on 25 May 1941.
Hello All, Just to be clear, I believe we have established that the towing signal was actually sent during the final battle, at Churchill's insistence, after the battleships had been engaging Bismarck for some time. I have shown a hand written letter from Tovey to Pound sent on arrival in Scapa indi...

Re: Titanic tourist submersible goes missing with search under way
Hi All, There are muddled (uninformed) references to using radio underwater *, but my understanding is that these deep diving units use acoustic transmission for comms which can struggle at great depth (ie range) and can be be cut off by shadowing by the wreck's hull.

Re: Hypothetical: The British detect Bismarck with a ship-borne Walrus at 0900 on 25 May 1941.
Hi Michael L, We are at the sensitive boundary of naval tactics and politics here. The actual timing and origin of the "towing" signal has been debated at length on this site. It was pure Winstonian hyperbole, dictated to and forced upon Pound under extreme pressure as the Prime Minister w...

Re: Shipborne aircraft - Walrus and Arado AR196 - Lost Opportunities?
Hi Michael L From Ellis' report on Suffolk's operations in ADM 534/509 During the turn at 0325 the wind, now force 6, carried away the securing gear of the controls of the only aircraft on board , which was on the catapult, causing damage necessitating extensive repairs which took some days to compl...

Re: Shipborne aircraft - Walrus and Arado AR196 - Lost Opportunities?
Hello All, As has been observed, the weather conditions during the Chase were extremely poor and it would have been almost certain that an aircraft launched would be destroyed on attempting to land on the sea for recovery. The Arado design in particular suffered from engine failures due to cylinder ...

Re: Chaser Gun on Paddle Steamer
Hi All, They had to reposition standing rigging for it to fire? Amen to those answers above. It was more a case of clearing the windward sheets to the jibs out of the way. Also we are not talking about the virtually continuous naval warfare of the 18th and early 19th century. Some of these vessels p...

Hi All, I think is a conjectural model of HMS Birkenhead, which was one of the first iron hulled RN warships. However as answered elsewhere, these frigates were downgraded due to worries about fracturing under enemy fire. Re-designated as a troopship she was completed with a built up foc'stle she wa...
