These are some navigational items gleaned from the pages of Lloyd's List. They are given here as provided in the journal:
April 3rd Titanic: 150 miles E of Fastnet - Lizard 10.30am
April 4th Olympic: bound W 70 miles SE - Brow Head 9.6am
April 11th Titanic: bound NW 40 miles W of Lizard 23 knots - Brow Head 5.30am
April 12th Titanic: 250 miles W - Brow Head - 3.46am
Unfortunately there are very few known navigational points during the ship's short life; one of which was the mention that the Titanic passed closer to the shoreline in South-west England than other ships had.
