Where is this number coming from?
Broadly, from this article:
http://www.titanicology.com/Titanica/TrimAndHeel.pdf by you Sam. I am following that along with related opinions from other researchers who shall remain nameless for the time being.
Based on what Lightoller said about him giving the gangway door order to Nichols while they were working on Lifeboat #6 and blending that with your chronology mentioned by Thomas in post #5 of the "Accurate Timeline" thread , I roughly calculated that the boatswain and his men tried opening that port side D-deck gangway door around 01:20am. Going then by your own "Time & Heel" article link above, the
Titanic was about 4-degrees down by the head at the time; a few other researchers have suggested that it was closer to 5-degrees and so I said "about" 5-degrees in my post above, which could be anything between 4 and 5 degrees.
Mind you, I was not that far off the mark compared with a mutual old friend, a former Captain and marine investigator, who defended Lowe's statement that the
Titanic was between 12 and 15 degrees down by the head when the Fifth Officer first arrived on the boat deck.
If that were true, then the forward well deck would have been awash and forward part of the forecastle would have been under water.
Well, in that same Time & Heel article, you have the
Titanic down by 5-degrees at the head by around 01:45am. The associated picture shows the prow still clearly above the water and a bit of the side of the ship along the forward well deck also just visible above the waterline. Would flooding as you mentioned above have taken place at 5-degrees trim? I thought not.
The next picture in your article with the bow now down by 6-degrees shows both eventualities very likely, of course.
Sam Halpern do you have a view on all this please?
Yes, I would also very much like to hear Sam's views on the chain of events that could have led to the port side gangway door on D-deck being found open on the wreck. In particular, I am finding it very hard to imagine what Boatswain Nichols, whom I consider to have been a very experienced and reliable sailor, thought and did during that trip below. I cannot accept that he would have ordered the door to be left open and although I have agreed with Thomas that they might have inadvertently not re-closed it properly, I find it hard to believe that Nichols himself would have done that. One possibility - and I stress that this is only my conjecture - is that after deciding to reclose the gangway door, Nichols ordered a couple of his men to secure it and that
they did not do it properly.
