Sloop Yacht Kathleen, San Francisco, San Francisco County, CA

Significance: The Kathleen is a shoal-draft centerboard sloop of the kind that dominated yachting on San Francisco Bay from the 1850s until about 1910. Built on North Beach in 1904–1905 by the Italian immigrant boat builder S. O. Pasquinucci for Frank Raymond, a clerk and later grocer, the boat was used for both cruising and racing, and sailed against the most significant racing yachts on the bay in the decades surrounding World War I. Rendered obsolete by changes in racing-boat rules and design, the Kathleen was modified into a yawl with a ballasted keel in 1930 and continued to be sailed for recreation on the bay for another seven decades, two of them in the ownership of Palo Alto businessman and civic leader Edward C. Thoits and four under the care of Harry Smith of Mill Valley and his son Hap. The yacht's wood hull was encased in fiberglass in the 1950s to reduce maintenance, a step that contributed to the boat's unusually long life. The San Francisco Maritime National Historical Park collected the Kathleen in 2011, recognizing it as a rare artifact representing the early world of yachting on the bay
