The official name of the ship is RMS Titanic. The R.M.S. stands for Royal Mail Ship, the Titanic being commissioned to carry mail. The S.S. designation that appears in the name of other ships stands for SteamShip. The life preserver ring revealed at the start of the Titanic's voyage and elsewhere should have been imprinted R.M.S. Titanic instead of S.S. Titanic.
As the ship hit the iceberg; a tear, though which water is pouring is seen in the engine room. The damage to the ship was in the first third of the ship. Water that got to the rear of the ship did so by getting over bulkheads that were not built water tight.
