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.
The R/V Questuary has a long tradition of providing assistance to scientists, students and educators. The R/V Questuary has been equipped with an A-frame and dual hydraulic winching capabilities for oceanographic instruments and equipment.
The R/V Questuary can transit water as little as three feet deep and is capable of hydrographic sampling, instrument towing, surface and bottom trawling, sediment coring, geophysical surveying and scientific dive support.
The R/V Questuary is equipped with a SeaBird SBE-19 conductivity, temperature and depth profiler, SeaBird SBE-45 thermosalinograph, SCUFA fluorometer and an underway data acquisition system that records water parameters. All instruments and equipment are available to the research scientists aboard the vessel. More information can be found on our vessel specifications page.
