The Ruby E was the former U.S. Coast Guard Cutter Cyane WPC-105 launched in 1934. The vessel is 165 feet long, has a beam of 38 feet and was diesel powered. Her original mission was to interdict "Rum Runners" smuggling liquor from Canada during the prohibition era. During World War II she performed anti-submarine patrols off Alaska. The Cyane was decommissioned in 1950 and converted to a fish processing ship.  Ironically she was later seized for drug smuggling off South America.  The Cyane was finally sold as a salvage vessel and renamed the Ruby E. The vessel was sunk as an artifical reef off San Diego, CA on June 18, 1989 in Mission Bay's "Wreck Alley". The Ruby E failed to sink as planned due to hidden compartments previously used for illegal activities. The 150 ton vessel has been prepared for divers by removing hatches and equipment. She lies upright 85 FSW.
