A Brief History of the Douglas Dolphin in RAAF Service by Paul McGuiness The Dolphin was built by Douglas Aircraft in 1930 as the "Sinbad," a pure flying boat without wheels. The Sinbad was intended as a luxurious flying yacht for America’s many millionaires but the Great Depression prevented any sales. Undaunted by the lack of demand, Douglas improved the Sinbad in 1931 so that it was amphibious, and could land on water or land. The improved aircraft was named "Dolphin", however this did not represent the end of development, as many more improvements were made, including an increase in the length of over a foot and several changes were made to the empennage, engine nacelles and wings. Douglas managed to attract the interest of the United States Coast Guard who not only bought the Sinbad, but 12 Dolphins and the success of the Dolphin helped the Douglas Aircraft Co. survive the Great Depression. The first two production Dolphins were purchased by Wilmington-Catalina Airlines to fly passengers between Los Angeles and Santa Catalina Island, becoming the first successful Douglas airliners. Other Dolphin owners included William Boeing, the founder of the Boeing Company, and Philip K. Wrigley, the son of the founder of the William Wrigley Jr Company. William K. Vanderbilt bought two with custom interiors for use from the Vanderbilt yacht Alva as flying tenders. Standard Oil of New Jersey purchased two aircraft for exploration use. Its outstanding success, both with the Coast Guard and private operators, attracted the attention of the US government with the result that further Defence contracts were awarded for the US Army and US Navy. The Army received 24 as transports, bearing the designations C-21 and C-26, later becoming observation amphibians (OA); while the Navy received 10 as RD transports. There were a total of 58 Dolphin aircraft built over the life of its production run between 1931 and 1934. The RAAF operated a total of four Dolphins: NC42186 (A35-1) operated in New Guinea on oil survey work with civilian operators until it was donated to the RAAF in June 1940; NC12212(A35-2) was operated by the Wilmington-Catalina Airline Ltd in the USA until purchased by the Australian Government; NC982Y (A35-3) was operated by the Crosley Radio Company in the USA until purchased by the Australian Government; and, NC14204 (A35-4) was operated by the Wilmington-Catalina Airline Ltd in the USA until purchased by the Australian Government. The Dolphin was only used as a stop–gap seaplane trainer and squadron hack at RAAF Base Rathmines until sufficient numbers of Catalinas were available. In service they proved difficult to maintain because of spares unavailability. Aircrew found them easy to fly and, given their ancestry, quite comfortable and spacious when compared to other seaplanes of the era. Apart from the spares availability issue ground crews found them easy to maintain. Three of the four Dolphins were converted to components during the war and the lone survivor was sold to a civilian operator after war’s end.
