The California Office of Spill Prevention and Response (OSPR) stated that the U.S. Coast Guard and the OSPR have confirmed that an
intermittent oil spill in San Mateo vicinity has been traced to the SS JACOB LUCKENBACH. The vessel sank on July 14, 1953 approximately seven miles southwest of the San Francisco Lightship after colliding with the SS HAWAIIAN PILOT. The Coast Guard's original Report of Investigation
reveals that the collision was caused, in part, by poor use of radar.
