Titanic carried a total of 20 lifeboats: 14 standard wooden Harland and Wolff lifeboats with a capacity of 65 people each and four Englehardt "collapsible" lifeboats (identified as A to D) with a capacity of 47 people each. In addition, she had two emergency cutters with a capacity of 40 people each.
Titanic had 16 sets of davits, each able to handle 4 lifeboats. This gave Titanic the ability to carry up to 64 wooden lifeboats which would have been enough for 4,000 people – considerably more than her actual capacity. However, the White Star Line decided that only 16 wooden lifeboats and four collapsibles would be carried, which could accommodate 1,178 people, only one-third of Titanic's total capacity. At the time, the Board of Trade's regulations required British vessels over 10,000 tons to carry 16 lifeboats with a capacity of 990 occupants. Therefore, the White Star Line actually provided more lifeboat accommodation than was legally required. At the time, lifeboats were intended to ferry survivors from a sinking ship to a rescuing ship – not keep afloat the whole population or power them to shore
As I am not a native English speaker I might have misunderstanding some of the posts here.
I thought you assume IOTL the Titanic had enough lifeboats for all on board - which it did not have.
Sorry if I had misread something...
