The Sloop Kathleen is currently part of the San Francisco maritime National Historic Park and is believed to be the second oldest yacht on San Francisco Bay. The forty-foot sloop was built as a yacht near Fisherman's Wharf by Salvatore Pasquinucci in 1904 and served as a pleasure boat on the bay for 107 years. The design of this vessel a centerboard sloop yacht was developed in New York City in the 1840s, the design evolving from local fishing boats noted for their speed under sail. The design was characterized by a wide and shallow hull. Introduced to San Francisco Bay in the 1850s, the sloops worked well on the shallow waters of the Bay and Delta. The popularity of the sloop grew, as more prosperous urban yachtsmen cruised and raced the craft.
