A disproportionate number of men were left aboard because of a "women and children first" protocol for loading lifeboats.
At a.m., she broke apart and foundered with well over one thousand people still aboard.
On 14 April, four days into the crossing and about 375 miles (600 km) south of Newfoundland, she hit an iceberg at p.m. The collision caused the 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.
Meanwhile, passengers and some crew members were evacuated in lifeboats, many of which were launched only partially loaded.
A high-powered radiotelegraph transmitter was available for sending passenger "marconigrams" and for the ship's operational use.
Thomas Andrews, chief naval architect of the shipyard at the time, died in the disaster. The first-class accommodation was designed to be the pinnacle of comfort and luxury, with an on-board gymnasium, swimming pool, libraries, high-class restaurants and opulent cabins.
Public inquiries in Britain and the United States led to major improvements in maritime safety.
One of their most important legacies was the establishment in 1914 of the International Convention for the Safety of Life at Sea (SOLAS), which still governs maritime safety.
The ship carried 16 lifeboat davits which could lower three lifeboats each, for a total of 48 boats.
However, Titanic carried only a total of 20 lifeboats, four of which were collapsible and proved hard to launch during the sinking.
