Lightship RELIEF underway. "Substitute for 'NAME' lightships: When a 'name' lightship of the U. S. Coast Guard must return to port for overhaul or repairs, her place on station is taken by a RELIEF lightship, such as the WAL-504, shown here. San Francisco, California, is this relief vessel's home port." [ref. NF 10/1953, no page]
