The sloop Clearwater’s first sail of 2012 is still about a month away, but fans of the 108-foot-long tall ship – a replica of the sloops that transported passengers and freight up and down the Hudson River in the 19th century – and the nonprofit environmental organization that it represents can find out what she has been up to over the winter at the Clearwater Family Open Boat Days. The event will be held on March 24 at Lynch’s Marina, located at 2 Ferry Street Clearwater in Saugerties.
