BERKELEY
Also known as: Ferry BERKELEY
Why it's listed
Berkeley is a steam ferryboat built in 1898 by San Francisco's Union Iron Works and now moored near B Street Pier on San Diego Bay as a museum vessel. She is double-ended, 289 feet long, with a steel hull, wooden decks and superstructure, and seating for 1,750 passengers. She worked San Francisco Bay for about sixty years before retiring in 1958, and she reached San Diego in 1973. Berkeley was the first propeller-driven ferry to operate on the Pacific Coast, though she proved hard to handle while docking. Her importance lies in how much of the original vessel survives. She keeps her triple-expansion engine, pumps, gauges, valves, steam steering gear and ventilating system, apart from a 1924 change to oil-fired boilers. The machinery now runs on compressed air. The ornate second-deck passenger cabin, with carved wood, brass and stained glass, also remains. She is recognized for her role in maritime history, transportation, naval architecture and engineering.
Significance in brief: The nomination calls Berkeley the oldest essentially unmodified passenger and car ferry in the United States and the best of three surviving propeller-driven double-ended ferries. She is the only American ferry that keeps her original 19th-century steam plant unmodified. The plant, like the hull, was built by the nationally important Union Iron Works. She represents ferry service at San Francisco and late 19th-century marine steam technology.

What listing means for this property
National Register listing is honorary: it recognises significance and does not restrict what a private owner may do without federal money or permits.
