What was the purpose of the Titanic's inner hull?

Answer 1

It meant to strengthen the ship. Titanic's steel hull, the main body of the ship, had been reinforced with a second hull fitted inside. That is why people used to say the Titanic was unsinkable, so this belief lulled everyone on board into a false sense of security, which was to have tragic consequences.

Answer 2

The purpose of Titanic's double-hull was for safety. The intention was to protect her from any reasonable collision scenario.

Answer 3

Titanic's double-hull was a safety feature to stay afloat even if suffering a blow to out it's outside hull.
