The USS Opal (PYc-8) was originally constructed as a luxurious motor yacht named Coronet in 1928, designed by Cox & Stevens and built by Germania Werft in Kiel, Germany. This steel-hulled vessel was crafted for American businessman Irving T. Bush and reflected considerable opulence for its time. Measuring a length suitable for long-range cruising, Coronet featured a spacious interior that included a library, a living room with an open fireplace, a dining room, and six staterooms, each equipped with its own bathroom. It was powered by diesel engines, enabling a substantial range of approximately 7,000 miles, making it well-suited for extensive voyages. The yacht served as a pleasure vessel in the late 1920s and early 1930s, cruising the Mediterranean and participating in New York Yacht Club events. During the 1930s, it remained in South Florida, specifically near Miami, maintained and ready for service but largely inactive. In 1941, Coronet was purchased by the U.S. Navy and converted into a patrol vessel at Merrill-Stevens Drydock Co. in Miami. Commissioned as USS Opal (PYc-8) in June 1941, it was assigned to the 10th Naval District, with initial patrol duties based out of Guantanamo Bay, Cuba. Its operations included patrolling off Cuba and the Greater Antilles, as well as escort missions between Guantanamo and Trinidad, especially during the early months of 1943. The vessel was also upgraded with new sound detection equipment at Charleston Navy Yard in October 1941 to enhance anti-submarine capabilities. In September 1943, the USS Opal was reassigned to serve as a training ship for Ecuadorian naval crews under the Lend-Lease Program, during which it was renamed Manabi. The U.S. officially sold the vessel to Ecuador in 1949, after which it was decommissioned from U.S. service and struck from the Navy List. The vessel was eventually scrapped in Ecuador in 1960. Throughout its career, USS Opal exemplified dual military and civilian maritime uses, transitioning from a luxurious private yacht to a wartime patrol vessel and later to a training ship for the Ecuadorian Navy.
