The famine replica ship, the Jeanie Johnston, has left United States waters after a record number of visitors boarded the vessel at her last port of call, Portsmouth in New Hampshire.
6,000 people boarded the ship during the past three days.
Later today the ship is due at her first port in Canada, St Andrew's in New Brunswick.
She will complete her visit in late September when she calls to Grosse Ile, which was the Quebec quarantine station where thousands of Irish emigrants arrived.
The vessel arrived in Florida in April and began sailing north, attracting huge interest from Irish-American communities during stops on Long Island, Boston and other locations.
