The Savoia-Marchetti S.55 was a double hulled flying boat produced in Italy, beginning in 1924. Shortly after its introduction, it began setting records for speed, payload, altitude and range. The S.55 featured many innovative design features. All the passengers or cargo were placed in the twin hulls, but the pilot and crew captioned the plans from a cockpit in the ticker section of the wing, between the two hulls. The S.55 had two inline contra-rotating propellers, mounted in tandem. The engines were canted sharply at an upward angle. Two wire-braced booms connected the triple-finned tail structure to the twin hulls and wing. Even though its design was unusual, the Savoia-Marchetti S.55 was a remarkably airworthy craft. In 1926, the S.55P prototype set 14 world records for speed, altitude and distance with a payload. The S.55`s greatest successes, however, were its many flights between Europe and the Americas. The aircraft went on to serve in the Regia Aeronautica as a long-range bomber and patrol aircraft, but by World War II, the last S.55s were no longer serviceable and were in reserve.
