What was the name of Christopher Columbus's fourth ship?

"He only had 3.

srry 2 burst ur bubble wuhtever ur name is but he really had 4 haha

Sorry to burst your bubble as well friend, but there were three. The Nina was simply a nickname he gave to his favorite ship, whose real name was actually the Santa Clara. That's still only three."

The ship you are referring to was written about in 1992 by Marinella Bonvini-Mazzanti. Associate Professor of History at the University of Urbino, Italy after finding records indicating a fourth ship.

It was later determined that the ship was a "fusta" and also not part of the official voyage because it was privately funded.

I hope this answers the question more completely, without 'bursting your bubble'.
