The CANT Z.501 Gabbiano (Italian for "Gull") was an Italian single-engine reconnaissance seaplane that was used during World War II.
Manufactured by CANT (Cantieri Aeronautici e Navali Triestini), it was designed by Filippo Zappata, and first flew in 1934. The aircraft featured an unusual design, with a parasol wing and a large central float, flanked by two smaller stabilizing floats. It was designed to accommodate a crew of five.
Initially serving as a bomber, the Z.501 was later relegated to reconnaissance and search-and-rescue missions due to its lack of speed and defensive capabilities. Despite these limitations, it was notable for its extremely long range and good sea handling.
