RMS Titanic was a boat.
RMS Titanic ( [ taɪˈtænɪk ] ) was a British passenger liner that sank in the North Atlantic Ocean in the early morning of 15 April 1912 , after colliding with an iceberg during her maiden voyage from Southampton to New York City . The largest ship afloat at the time it entered service , the RMS Titanic was the second of three s operated by the White Star Line , and was built by the Harland and Wolff shipyard in Belfast . Under the command of Edward Smith , who went down with the ship , Titanic carried some of the wealthiest people in the world , as well as hundreds of emigrants from Great Britain and Ireland , Scandinavia and elsewhere throughout Europe seeking a new life in North America . The collision caused the ship 's hull plates to buckle inwards along her starboard ( right ) side and opened five of her sixteen watertight compartments to the sea ; she could only survive four flooding .
