Marjorie Elizebeth Zeilenga, 64, vanished from her 30-foot sailboat City Scape during a sailing trip that began in San Francisco Bay on September 20, 1998. She and her husband were headed to Santa Cruz to visit their daughter when they ran into high winds and large swells north of the Ano Nuevo State Reserve. Around 4:00 a.m., the boom on the mainsail broke and they turned back toward Half Moon Bay for repairs.

While Marjorie was at the helm and her husband was securing equipment, a large wave struck the boat and threw her overboard. She was wearing a life vest but did not have a safety line or harness attached. Her husband briefly saw her in the water before she disappeared. The Coast Guard conducted an extensive search and her husband searched as well, but her body was never recovered and she is presumed to have drowned and remains classified as an endangered missing person.

Are there any sailors or local boaters who remember conditions that night or who might have been in the Half Moon Bay–Ano Nuevo area on September 20, 1998?
