The SS City of Chester was a steamship constructed in 1875 by John Roach & Sons in Chester, Pennsylvania. She measured approximately 1,106 gross register tons (GRT) and 785 net register tons (NRT), with a length of 202 feet (62 meters), a beam of 33.2 feet (10.1 meters), and a depth of hold of 15.9 feet (4.8 meters). Powered by two boilers and a compound steam engine rated at 600 indicated horsepower, she was a robust vessel designed for coastal trade and passenger service. Originally built for coastal routes, the City of Chester was purchased in October 1876 by the Oregon Railroad Co., and shortly thereafter, she was brought from New York around South America to Portland, Oregon, in March 1877. She replaced the steamer John L. Stephens in the Oregon coast-wise trade. The ship was notable for being the first vessel to utilize the newly opened East River channel through Hell Gate and subsequently operated along the route from Portland to San Francisco, including service to Eureka and other California coastal towns. At the time of her sinking, the City of Chester was chartered to the Pacific Coast Steamship Company, running a route from San Francisco's Broadway Wharf to Eureka and other northern California ports. On August 22, 1888, while outbound to Eureka with 90 passengers during dense fog, she collided with the larger liner SS Oceanic inbound from Hong Kong. The collision was caused by tidal currents that carried the smaller vessel into the path of the Oceanic, despite the ships seeing each other. The impact cut the City of Chester nearly in two, and she sank within approximately six minutes, resulting in the loss of sixteen passengers—including two children—and three crew members. The wreck lies in 216 feet (66 meters) of water just inside the Golden Gate and was rediscovered in May 2013 by NOAA's Office of Coast Survey using multi-beam sonar. The sinking remains one of the most tragic maritime disasters in San Francisco Bay history. An exhibit dedicated to the City of Chester is planned at the Gulf of the Farallones National Marine Sanctuary, highlighting her maritime significance and the enduring memory of her service and tragic end.
