Which vessel was designated the flagship of America250's Sail250 fleet?

USCGC Eagle was designated the flagship of America250's Sail250 fleet.

Eagle is a United States Coast Guard sailing training ship and one of the best-known tall ships associated with the United States. During Sail250, it served as the fleet's flagship while participating in the maritime commemoration of the nation's 250th anniversary.

The ship was originally built in Germany as Horst Wessel and was acquired by the United States after World War II. It entered Coast Guard service in 1946 and has trained generations of cadets and officer candidates in navigation, seamanship, and leadership.

Eagle is easy to confuse with USS Constitution, the famous U.S. Navy sailing warship based in Boston. Constitution is historically important, but the Sail250 flagship designation belonged to Eagle. The fleet also included famous foreign ships such as Italy's Amerigo Vespucci and Mexico's Cuauhtémoc.
