It had 16 decks that each acted as its own lifeboat.
There were 16 watertight compartments and a double bottom.
They had figured out how to make the ship out of buoyant materials

There were 16 watertight compartments and a double bottom.

Explanation:

The builders of the Titanic ship believed the ship was unsinkable because of the many fail-safe mechanisms that was built into the large ship.

An important safety mechanism that gave the builders much confidence about the Titanic unsinkable was the construction of 16 watertight compartment S and a double bottom which would make it almost impossible for the ship to sink.
