Perhaps there are two bottles:

A broken champagne bottle used to christen [famous ship] which gives any ship it's placed on excellent luck and makes the ship much harder to sink.

The Unbroken Bottle from the Titanic: Causes nearby ships to experience disasters of various kinds. Using it to christen a ship guarantees the ship to sink on its next voyage.
