David G. Brown wrote:The ship needed a contingency reserve. The question is how much? Today, we tend to consider safety reserve in percentages of fuel remaining. Since writing "Last Log," I've come to realize this is not a correct way to look at Titanic's situation in 1913. Unlike many Titanic researchers I reserve the right to refine my work over time and make corrections based on new information. In this case, I realize that percentages of fuel have no bearing on 1913 reality and must be discarded. It was not the percent in reserve that was critical, but the actual tonnage held back for contingencies.
David G. Brown wrote:The closest port suitable for sheltering an Olympic class vessel without navigational risk and with suitable coaling facilities was Halifax. No ship has "enough" fuel aboard if it cannot safely divert from its port of destination to a second port. For Titanic, that meant it had to be able to complete its New York run with enough fuel to get to Halifax. It would have taken Titanic about a day and a half to go from New York to Halifax. From an operational standpoint, this is two days. At 650 tons per day, that's a minimum of 1,300 tons required for a safe trip.
So, Mark's minimum 1,000 tons reserve was insufficient for the safety of the ship by 300 tons, or about a half-day's steaming. (In discussions of safety you always take the worst possible case. If, as Mark suggests, the ship burned less than 650 tons per day there would be no harm done...
David G. Brown wrote:I've seen predictions of 850 tons/day at 23 knots which seem reasonable. If that were true, then Titanic's fuel load at Southampton was insufficient for a seven day voyage as 5,950 tons would have been required and there would have been no reserve for safety. At 24 knots, Titanic would have needed a tow about a day out of New York because it would have run out of coal to fire the boilers. As I stated in my book, the fuel simply was not aboard for a trans-Atlantic record setting run, even if Titanic could have been pushed to the required speed.
David G. Brown, writing in The Last Log of the Titanic (2000) – Page 20 wrote: Despite the ship's fuel savings on the first two days, Captain Smith was correct in his attempt to persuade Ismay against increasing speed beyond 22.25 knots for the remainder of the voyage. Their ship did not have enough fuel onboard for such publicity stunts.
It is one of history’s curious footnotes that, except for an unfortunate encounter with an iceberg, Titanic might have earned fame for a different ignominy. Ismay's plan would have depleted the ship's supply of coal before it arrived in New York Harbor, possibly leaving it a helpless, drifting hulk. If that had happened, the entry of the world's largest liner into New York would have been at the end of a salvage ship's towing hawser.
David G. Brown wrote:But, using the tonnage numbers we do know, and reasonable assumptions about fuel burn, it appears Titanic did have enough fuel aboard for the intended voyage, and for reaching a suitable alternative port – but nothing more.

David G. Brown wrote:We have no authentic fuel consumption numbers for Titanic. So, we have to use the fuel consumption numbers postulated by Mr. Sanderson for Olympic. I believe Mark has quoted these numbers in at least one book he has published.
David G. Brown wrote:Simple division of distance by time tells us that from Queenstown to the accident scene Titanic averaged only about 19.6 knots.
David G. Brown wrote:As for attaching importance to beating Olympic's maiden voyage speed -- why? There would have been nothing to gain in making Olympic seem a slowpoke now that Titanic was the fleet speed merchant. The importance of a faster passage would more likely have been to the engineers who may have tweaked or changed something to gain improved performance. If Titanic was either making, or about to make Ismay's "speed run," I suspect -- but do not know -- that it was a test of engineering changes and not some alleged publicity stunt.
David G. Brown wrote:One other issue. There is no credible historic evidence for a speed of more than 22 knots, and that speed comes only from Boxhall. All of the other officers gave lower speeds. To claim either 21.25 or 22.5 knots as Titanic's speed as fact is academic fraud and I make no claims of any such speeds here. My use of 22.5 knots was for illustrative purposes only. I have seen alleged "proofs" of higher speeds, but they all require on assumptions based on navigational data from other ships, the wrong duration of the run, and/or an assumed recreation of the ship's location at 7:30 p.m. stars. It is permissible to say – as I have both in public and privately to Mark – that Titanic's speed was probably greater than the 22 knots Boxhall admitted. However, it is totally false to assert any higher speed as a proven fact.

As has been alluded to earlier in this forum, it was felt by Titanic's officers that any danger would be seen in time for the ship to take evasive action. This mentality was consistent with accepted navigational practices of the time. Every ship did it.
The ships only slowed down when the amount of ice they encountered started to cause concerns. Dave Gittins is the best one for the stats on this, but there were a number of ships in the general area that had stopped for the night because of ice.
The first real contact that Titanic had with ice was the collision itself. It never reached the ice field, it was unlucky enough to encounter an isolated berg on the fringes of that field.
The way you have put it, it seems (to me, anyway) as though Smith recklessly sped up even though he was obviously heading into danger. A lot of submissions to the inquiries, seeking to blame him, couched it in much the same way. Senator Smith's oratory also villified him. However, given that he was just following standard operating procedures, I think that's a bit harsh.
It was the Titanic disaster that proved definitively how potentially dangerous these practices were. Your stating that the reason to slow down was the ice warnings has the benefit of hindsight that this disaster afforded everyone after the fact. Smith didn't have that hindsight.
I like the approach of the British inquiry, which effectively stated that Captain Smith had made, in hindsight, a very grievious error, but that while his actions were considered understandable in light of hitherto current practice, the same actions should be considered negligent from here on in.
I would consider the same applies to all of Titanic's officers including Lightoller and Murdoch.
Cheers!

May I remind you that I am commenting on the Titanic, and not the Olympic.
However the explanation is that arrangements had been prepared for the Olympic to make an early arrival and in July it is daylight

>The tuesday arrival has been denied by both Bruce Ismay, and Harold Saunders, testified in the BWCI.
Both men were in the minority in their denials (and nobody named "Harold Saunders" testified at either inqujiry.) In fact, Ismay lied when he denied knowing that additional boilers were to be connected to the Titanic's engines on April 14th. Titanic was trying to better the maiden voyage crossing time of the Olympic, and she would have had to slow down in order not to arrive at the Ambrose light on Tuesday night.
>No provision was made for the ship to be received by The New York Harbour Authority, ie tugs, customs, stevadores, and other, before 7 am wednesday morning.
If that's true, how do you explain the Olympic's arrival in New York on Tuesday night on July 13, 1911?
See George Behe's "Titanic: Safety, Speed and Sacrifice" and Mark Chirnside's outstanding books on the Olympic-class ships for detailed presentations of the evidence which demonstrates conclusively that the Titanic was indeed expected to arrive in New York on Tuesday night.

You know full well this isn't true. I commented on one post in another thread where your misspelling made a difference in the meaning of your message; I have not commented on spelling or grammar errors in any of your other messages. Although everyone posting to the board is well-advised to use its spellchecker, spelling inaccuracies are not commented on unless the meaning of a message is unclear or confusing as a result.old salty wrote:he will read them now because he reads all my posts for spelling mistakes.
Here again, using "Saunders" instead of "Sanderson" changes the correctness of what was written. Misspelling "inquiry" doesn't.Gordon Simpson wrote:I thank you for correcting my misspelling of the name of a witness. I wrote "Harold Saunders" which was intended to mean "Harold Sanderson". It appears that we can all make spelling mistakes as shown by yourself when you spelled a word as "inqujiry"
Thanks for the kind words, Karl. Much appreciated.Karl Texler wrote:As regards Mark (MAB) - I find him a very fair and conscientious moderator of this forum.

Glad to hear that, old salty. Same hereold salty wrote:Idont have a problem with you, Mab, or anyone else on this site
We've had a fairly recent discussion of the Tuesday arrival issue on this board, including whether in this context "arrive" means "dock."Achmet Pamba quoting Gordon Simpson wrote:>....By arrive in New York, you >are meaning within the port. to be alongside, and " made fast". Or do you not mean New York ?
I mean arriving at the Ambrose lightship, which always marked the official record-keeping end point of a White Star voyage to New York.

Contemporary sources reflect the same differences in the use of the term "arrive." The news columns of, for example, The New York Times, almost invariably use "arrive" to mean "dock" but the shipping column often notes the arrival at Ambrose (or, sometimes, at the Bar) in reporting ship movements, especially for late arrivals when the ship didn't actually dock that night but remained at anchor until morning. The Ellis Island ship manifests also often have a date on them that's a day earlier than the ship's actual arrival at the pier, reflecting, as far as I can tell, when the manifest was presented to the immigration and quarantine officials.Gordon Simpson wrote:Salaam Achmet,
We appear to have different understanding of the expression.
" To arrive in New york."
