Could the weight of Coal force Titanic to keel over to port more during the sinking?
Survivor Lawrence Beesley said this:
(During the voyage)
"I then called the attention of our table to the way the Titanic listed to port (I had noticed this before), and we all watched the sky-line through the portholes as we sat at the purser's table in the saloon: it was plain she did so, for the sky-line and sea on the port side were visible most of the time and on the starboard only sky. The purser remarked that probably coal had been used mostly from the starboard side. It is no doubt a common occurrence for all vessels to list to some degree; but in view of the fact that the Titanic was cut open on the starboard side and before she sank listed so much to port that there was quite a chasm between her and the swinging lifeboats, across which ladies had to be thrown or to cross on chairs laid flat, the previous listing to port may be of interest."
(During the sinking)
"For some time before she sank, the Titanic had a considerable list to port, so much so that one boat at any rate swung so far away from the side that difficulty was experienced in getting passengers in. This list was increased towards the end, and Colonel Gracie relates that Mr. Lightoller, who has a deep, powerful voice, ordered all passengers to the starboard side. This was close before the end. They crossed over, and as they did so a crowd of steerage passengers rushed up and filled the decks so full that there was barely room to move. Soon afterwards the great vessel swung slowly, stern in the air, the lights went out, and while some were flung into the water and others dived off, the great majority still clung to the rails."

Unlikely. The list was more likely due to some measure of assymetric flooding with the list of the ship changing depending on how things either evened out or changed because of whatever open spaces the floodwaters went into.

Modern ships with out running on any coal,still manage to list before sinking.
Also Titanic was quarter the way though her voyage before she founderd,so titanic at the time of the disaster would have less coal,also there was a coal strike,so maybe Titanic had even less reserve coal. |

"Modern ships with out running on any coal,still manage to list before sinking."
That's because they are no better designed than Titanic. Her subdivision allowed water to spread across the ship fairly evenly. She listed to both port and starboard during the sinking, but the list was never severe. Titanic was only just short of modern standards for subdivision.

Dave:That was my point of my first post to the O/P,he mention about coal maybe the reason of the Titanic listing and I was disagree with him by saying that even modern ships list without any coal. I was trying to state that Titanic never list cause of her coal. |

Anna,
They used the ballast tanks and fresh water tanks to correct any serious list. Actually; some ships - even today - perform better with a slight list one way or the other. |

Oh the vauls? yes,i forgot.Like the subs,they have vauls to make it light or heavy (submerge or risen) Modern ships would have the same vauls for a purpose of an emergency? |

The Vaults. The subs use these to submerge and risen by flooding the sub with water or letting water go.
I am guessing Titanic never had this kind of Technoghy,with ships today,they use the same thing as a sub but I am not to shore in what way. |

Please use a spelling checker, then, and proofread your messages carefully. (I take it that "to shore" is supposed to mean "too sure"?) Some of what you write is kind of difficult to understand.

THE SCOTLAND ROAD IS A PASSAGE ON THE PORT SIDE E DECK. WHEN THE WATER REACHED THIS AREA THE SHIP STARTED TO LIST TO PORT. |

No they don't. They use ballest tanks for that.

The ballest tanks I actually meant too say,but I could not remember that name,I had thought that Vaults was another word use as a term for ballest tanks.
I did not think experts would not get it.
All the best. |

Ballast tanks on ships are used more or less to control the ship's list and trim. Can also be used to replace loss of fuel to keep the ship's stability within certain limits. On a submarine ballast tanks are used to control the degree of buoyancy as well. On the surface the sub would ballasted for positive buoyancy so it would float to a certain waterline. When submerged they would be ballasted more or less for neutral buoyancy so the sub can easily maneuver while submerged. In that case, the weight of the sub exactly weighs the same as the water it displaces.
