Annual restoration of the Historic Hudson River Sloop Clearwater! Each year, the Clearwater welcomes over 10,000 visitors to the Hudson River. Come get your hands dirty sanding, painting, making baggywrinkle, fixing block-and-tackle systems, and organizing our heavy items. Bring Warm clothing you don’t mind getting paint/varnish/grease on. This also happens to be the day of the Clearwater “Open Boat” party.
