Alexander Carlisle's '64 lifeboats'
Contrary to popular belief, there is no evidence that Alexander Carlisle or Harland & Wolff recommended to the White Star Line that more lifeboats should be fitted. What they did do is provide a new Welin davit design which would enable them to carry more lifeboats in the future, if the regulations changed. They also provided four additional semi collapsible boats for each ship. Comparing the number of lifeboats shown on the ‘Design “D”‘ concept which the White Star Line approved in July 1908 with Titanic as completed in April 1912, the number of lifeboats increased from 16 to 20.
