1911 (Atlantic Ocean) - (point of divergence) The Lusitania collides with an iceberg at the night of August 19th, capsizes and founders. Stricter safety regulations are introduced. The Olympic is quickly brought back to the ship yard for a refit and the Titanic is equally refitted.

1912 (Atlantic Ocean) - The Titanic starts her maiden voyage on April 10th. She sails across an ice field and spots an iceberg, with the red mark the Lusitania’s hull left after her collision with the iceberg one year before. The ship narrowly misses the iceberg, scraping it slightly, and continues sailing with only two flooded compartments. She makes it to New York and is repaired.

1916 (Atlantic Ocean) - The hospital ship Britannic collides with German destroyer G104. Meanwhile, the troop transport ship Mauretania is nearly sunk by a stray bullet from British battleship Dreadnought, but a section of the stern superstructure is blown up and the fourth funnel collapses. Both ships are taken to the nearest shipyard in Galway to be repaired and the Mauretania is redesigned without the fourth funnel.

1936 (Britain) - The superliner Oceania of the Cunard-White Star Corporation enters service. Rumors say that she was originally planned to be named after a queen, namely Victoria, but was instead named Oceania after the scrapped superliner Oceanic.
