Flynn's yacht, the 75-foot Sirocco, was built under the direction of an American, John Alden. It was launched in 1929 named the Karenita and, when sold the following year, it was renamed the Aviner. Over the next six years it went through the names, Simoon, Watchette II, and again Karenita. She was purchased by Flynn in 1938, at which time she was renamed Sirocco.
Being fairly slender and with limited accommodations, it was not ideal for cruising but it was prize-winning racing yacht. She went through several owners since Flynn and was listed for sale under her original name in 2018 for $145,000. Flynn later moved up to a 118-foot schooner the Zaca, the second of his with the same name, which was lost during a revolution in Mexico. The Zaca was requisitioned by the US Navy during the war, then returned to private use, to be bought by Flynn in 1945.
