Here are more details from the historic site:
The Relay Flotilla begins on June 6 in New York City and will reach its destination on June 13. Boat and yacht clubs along the way will send out their members to join the Flotilla as it heads north. As part of the Hudson-Fulton-Champlain Quadricentennial, on June 11 the Relay Flotilla will be paying its respects to Clermont State Historic Site, the historic home of Chancellor Robert R. Livingston, collaborator of Robert Fulton in the famed 1807 steamboat, the North River (popularly known as the Clermont) and a stop on the steamboat's maiden voyage.
Picnickers are welcome to witness this historic event from the grounds and share an exceptional view of the Flotilla free-of-charge at this afternoon sail-by. At 11:30 a.m., curator Ashley Hopkins-Benton will be giving a family-friendly talk on the 1909 Hoopla on the Hudson celebration and comparing it to the 2009 celebrations. Tours of the mansion will be offered for $5 per adult, $4 for seniors and free for children 12 and under beginning at 11 a.m. and running until 4 p.m. More information is at this Web site.
