HARTFORD, Conn. — A Connecticut judge has appointed a receiver to take over the operations and finances of the group that runs the state’s official flagship, the Amistad schooner.

State Attorney General George Jepsen requested the receivership. He filed court documents saying Hamden-based Amistad America Inc. has run up significant debt and its conduct has been “destructive” to its educational mission. A Hartford Superior Court judge appointed the receiver Thursday.

The 129-foot Baltimore clipper is a replica of a vessel taken over by African captives being brought to Cuba in 1839.

They landed on Long Island, but were jailed in New Haven. They were freed in a landmark U.S. Supreme Court case.
