In most I agree with you Scott, the only issue I'm having a problem wrapping my mind around is once Titanic began listing to port wouldn't she have kept that same list or more likely continued to list to port?
What would make her shift the list from port to starboard or vise versa? The only thing I can imagine causing it to shift is if the hull had a breach from the stress of the list. For example if she had an 8 degree list to port then the starboard hull might have had enough stress to partially buckle the hull.
If that had happened could that explain the two "explosions" heard by some of the survivors? It was said those two explosions were about 10 to 20 minutes apart. Possibly starboard hull buckling and then shortly after the port hull?
Wouldn't that be from boiler rooms 4 and 6? That would make sense as some simulations show a 10 to 20 minute time difference from the two boiler rooms flooding just before and during the final plunge.
I believe unfortunately that researchers have gotten as far as they can on the progression of the sinking and breakup with the knowledge we have and unless someone can make an interior dive of the Titanic we'll never have more to go on. But it is fun to try and speculate how it all happened!
One would have thought that as they shifted the coal from one bunker to another they would have altered the water in the ballast tanks to compensate for the change of trim.Hard to be sure, but it I think it had to do with both the flooding and the shifting of coal during the voyage. I heard during the 3rd day of the voyage in order to calm a fire in the coal bunker they moved a ton of coal to the other side of the ship which ended up giving it a slight list for the remainder of the voyage. Then once the flooding came - on the side of the ship that wasn't already listing due to coal - it reached a kind of equilibrium for a tiny bit before the water started to become heavier then the coal. And of course there's the issue of the gangway door.
Don't take my word on it tho. I'm nowhere near as knowledgeable as the other folks around here
Titanic did not capsize because her center of gravity was below her metacentric height. The metacenter is the theoretical center found by experiment. it is located on the centerline and around it the ship rolls. When the center of gravity is below this center, the ship will not over turn However, if the c of G rises due to weights or remove below it's position or loss of buoyancy, the two centers will eventually coincide and the ship will lurch right or left until equilibrium is reached. If the position of the C of G rises above the Metacenter, the ship will overturn. In one instance Titanic was very near to it when Wilde got everyone to move from one side to the other. In fact, the evidence of Baker Joughin suggests that eventually, just before the end, she lurched to port.One would have thought that as they shifted the coal from one bunker to another they would have altered the water in the ballast tanks to compensate for the change of trim.
