This is a replica of the Amistad, a Spanish schooner, which was transporting captives from Sierra Leone to become slaves in Cuba in 1839. The captives took over the ship but could not sail back to Africa and were captured and taken to New London, Connecticut where in 1841 after US Supreme Court ruling they were freed. https://www.mysticseaport.org/explore/vessels/amistad-replica-schooner/
