The USS Zaca (IX-73) is a wooden-hulled, schooner-rigged yacht with an auxiliary engine, originally built for private use but later serving as a naval vessel during World War II. Designed by Garland Rotch and constructed by Nunes Brothers Boat and Ways Co. in 1930 at Sausalito, California, Zaca was intended for global sailing with modern amenities of the era. The vessel features a classic schooner rig, complemented by an auxiliary engine, making her suitable for both traditional sailing and motorized propulsion. Initially owned by Charles Templeton Crocker, the Zaca was used throughout the 1930s for scientific expeditions around the world, primarily in the Pacific, including the Palmyra Atoll and the Galapagos. Crocker’s voyages contributed significantly to biological and environmental documentation, often involving scientists and artists such as Toshio Asaeda. The yacht was equipped for scientific research and exploration, reflecting Crocker’s dedication to discovery. During World War II, the U.S. Navy acquired the Zaca from Crocker on June 12, 1942, to serve in patrol and rescue operations along the California coast. She was commissioned shortly thereafter as USS Zaca (IX-73), classified as a miscellaneous auxiliary vessel, and assigned to the Western Sea Frontier. Her role was primarily as a plane-guard ship, tasked with rescuing downed airmen. The vessel operated in this capacity until she was relieved by escort frigates of Squadron 41. Zaca was taken out of service on October 6, 1944, and her name was struck from the Navy list in November of that year. Post-war, the vessel was transferred to the War Shipping Administration and later gained fame as the yacht owned by actor Errol Flynn. She appeared in the 1947 film "The Lady from Shanghai" and was the subject of the 1952 documentary "Cruise Of The Zaca," which showcased Flynn and his marine biologist father conducting scientific sampling. As of 2008, Zaca was privately owned by Roberto Memmo and berthed in Monaco, where she remains active in Mediterranean sailing events, often participating in prestigious races and cruises across the Aegean Sea. The vessel’s rich history spans exploration, military service, and cultural significance, making her an iconic maritime vessel.
