Search survey for S/V Tenacious: Gulf of Farallones and approaches to San Francisco Bay

On January 28^th, 2007, Jim Gray sailed his 40 foot sailboat, Tenacious, on a day cruise to the Farallon Islands off San Francisco and was reported overdue when he didn't return as scheduled. The immediate and comprehensive above water search for Jim and Tenacious was suspended on February 16, 2007. Shortly after this, Fugro Pelagos, Inc., conducted an extensive search of the seabed to look for evidence of the whereabouts of the sailing vessel, Tenacious. Approximately 1000km² was surveyed between February, 2007 and May 31^st, 2007 when the effort was suspended.

This paper summarizes the search survey for S/V Tenacious, the areas and techniques used in the survey, the findings of the survey, and the results and recommendations provided by Fugro Pelagos, Inc.
