motorboat USS California was completed in 1910 and served in World War I on harbor patrol duty. The two-masted gaff-rigged schooner California, built as the racing sailboat Zodiac in 1924, was modified for pilot service after being acquired in 1931 by the San Francisco Bar Pilots Association for use as a pilot boat. California served as a pilot vessel until 1972 when the schooner was the last sailing pilot vessel in the United States. The schooner was purchased in 1978 and again named Zodiac. The vessel is one of few surviving sailing pilots still in existence. The two-masted gaff-rigged schooner Adventuress, launched in 1913, also saw service as a pilot boat, and during World War II served with the United States Coast Guard. The Zodiac and Adventuress are both listed with the National Register of Historic Places and are now cruising in Washington state after restorations. The container ship COSCO Busan struck the fender system of Delta Tower of the San Francisco–Oakland Bay Bridge at 8:30 a.m. on 7 November 2007, causing damage to the ship as well as slight damage to the tower fender system. The ship's hull was breached, with damage to a water ballast tank and two fuel tanks, with approximately 53,653 gallons of fuel oil leaked and environmental contamination from the oil spill. The accident was investigated by the Board of Pilot Commissioners as well as by the US Coast Guard and the National Transportation Safety Board. The investigation by the Pilot Commission found misconduct by the licensed pilot in the form of pilot error in navigating the vessel and moved to revoke the pilot's license. However, the pilot surrendered his license before a hearing was held. The investigations by the Coast Guard and NTSB also found the pilot at fault. Neither investigation faulted the Commission's licensing nor oversight of the pilot in question. In 2011, the Commission received and accepted a landmark study on pilot fitness, conducted by Dr. Robert Kosnik, B.Sc, M.D., D.I.H. of the University of California, San Francisco. This study formed the basis of new regulations concerning pilot fitness determinations within the jurisdiction of the Board and has the potential to set a new standard worldwide on pilot fitness for duty.
