Amerigo Vespucci, the Italian explorer after whom America is named, did not have a single ship named after him during his lifetime. However, there is a famous Italian Navy training ship named Amerigo Vespucci in his honor. This ship was launched in 1931 and is still in use today.
During his voyages, Vespucci sailed on various ships, but none of them were specifically named after him. His explorations were conducted on ships provided by the Spanish and Portuguese crowns, and these ships typically had names that reflected their sponsors or other significant figures of the time.
