Santa Rosa was a Steel Electric-class ferry built in Alameda, California, for Northwestern Pacific Railroad.

She started out serving Southern Pacific Railways on their Golden Gate Ferries line on San Francisco Bay.

[1] The ferry was returned to San Francisco after her sale in 1968, but sat largely unused until purchased by Hornblower Cruises in 1989.

Hornblower restored her aft wheelhouse in an attempt to make her look like her original profile from 1927, however the passenger cabin retained the remodeled outline from her 1941 single-end conversion.
