Final answer:
Thomas Andrews recommended 64 lifeboats for the Titanic, but the ship only had 20 lifeboats.
Step-by-step explanation:
Thomas Andrews, the chief naval architect of the RMS Titanic, recommended 64 lifeboats for the ship. This number was based on the 1912 British Board of Trade regulations, which only required ships over 10,000 tons to have 16 lifeboats. However, Andrews felt that the Titanic should exceed this requirement and provide enough lifeboats for all passengers and crew. Unfortunately, the Titanic only had 20 lifeboats, which was half of what Andrews had recommended.
