Sinking of the RMS Titanic list to starboard was caused by asymmetrical flooding of the starboard side as water poured down a passageway at the bottom of the ship. When the passageway was fully flooded, the list corrected itself but the ship later began to list to port by up to ten degrees as that side also flooded asymmetrically. "Titanic"s down angle altered fairly rapidly from zero degrees to about four and a half degrees during the first hour after the collision, but the rate at which the ship went down slowed greatly for the second hour, worsening only to about five degrees. This gave
