Which ship holds the record for the fastest westbound Atlantic crossing by an ocean liner?

The SS United States holds the record for the fastest westbound Atlantic crossing by an ocean liner.

The American liner set the record in July 1952, completing the voyage from Bishop Rock, near the Isles of Scilly, to the Ambrose Light off New York in 3 days, 12 hours, and 12 minutes. Its average speed was about 35.6 knots.

The ship was designed by naval architect William Francis Gibbs and built by the Newport News Shipbuilding and Drydock Company. It entered service with United States Lines and was intended to carry passengers and troops quickly during the Cold War.

The SS United States won the westbound Blue Riband from RMS Queen Mary. It remains the holder of that westbound record, although the ship has been laid up since 1969. The eastbound record and the overall interpretation of Blue Riband records can involve different historical comparisons, so the direction of the crossing matters.
