What is "christeen"

Christeen is the oldest oyster sloop in the United States and was declared a National Historic Landmark in 1992.

She was built in 1883 in Glenwood Landing, New York as a gaff-rigged sloop. She had several homes including Essex, Connecticut, but in 1992 she arrived back in the hamlet of Oyster Bay, New York at the WaterFront Center. Funds were raised and over the next seven years, she was restored and relaunched. She currently serves as a working museum ship, offering educational tours of Oyster Bay and Cold Spring harbor. __NOTOC__
