The CANT Z.501 Gabbiano (Italian: Gull) was a parasol wing flying boat with two outboard stabilizing floats. The engine was contained in a nacelle mounted in the middle of the wing. It had a crew of 4–5 men and served with the Italian Regia Aeronautica during the Second World War as a reconnaissance airplane. During its debut in 1934, it set a world distance record. It was obsolete by 1940, but was still used throughout the Second World War, suffering many losses. A few remained in service until 1949
