The Cunard Line's RMS Mauretania makes a record-breaking westbound crossing of the Atlantic, that will not be bettered for 20 years.

RMS Mauretania was a British ocean liner designed by Leonard Peskett and built by Swan, Hunter & Wigham Richardson on the River Tyne, England for the Cunard Line, launched on the afternoon of 20 September 1906. She was the world's largest ship until the launch of RMS Olympic in 1910. Mauretania captured the eastbound Blue Riband on the maiden return voyage in December 1907, then claimed the westbound Blue Riband for the fastest transatlantic crossing during her 1909 season. She held both speed records for 20 years.
