About The R/V Questuary

Research Vessel Questuary in San Francisco Bay


The R/V Questuary is the only California State University operated research vessel exclusively engaged in scientific research in the San Francisco Bay and Delta region. The vessel is a 38 foot aluminum monohull built in 1975 and acquired by San Francisco State University in 1991. Operated by Romberg Tiburon Center for Environmental Studies, the University field station in Tiburon, California, the R/V Questuary serves the needs of the Bay Area research and academic communities through scientific and educational cruises.
