One of the most outrageous spectacles in aviation is when a high-performance airplane takes off gracefully out of a lake or the open sea and defies all odds in a most dramatic manner. These machines are not anchored to runways like conventional planes and therefore have unmatched flexibility in their operation. Such freedom, however, is accompanied by tremendous engineering problems that ensure that each successful design is a minor miracle of an invention.

Important Seaplane Take-off features

• Does not use runways
• Has to have float or durable hull
• Faces added drag from water resistance
• Requires strong engines to lift-off
• Combines marine and aviation design challenges

This bi-purpose design implies that a seaplane has to operate as a good plane and a seafarer. The weight, aerodynamics and structural strength of the structure have to be managed by the designers with care and stability on the water. Nonetheless, these challenges notwithstanding, engineers have reached unbelievable velocities with certain designs, demonstrating the fact that even the inhuman trade-offs between air and water may be defeated with ingenuity and determination.

1. Spitfire Floatplane – 377 mph

The account of the Spitfire floatplane starts in the period of World War II when Britain desperately needed planes which could be utilized without landing facilities. This need was emphasized by the German invasion of Norway, which compelled engineers to convert the legendary fighter into a water fighter. The immediate crisis outlived the deployment but the idea was interesting and was used in subsequent war tactics.

Highlights of the Spitfire Floatplane

• Designed to be used in war
• Based on the mythical Spitfire fighter
• Intended to operate without airstrips
• Merlin 45 powered
• Obtained phenomenal wartime speed

By 1944 the idea had reached its pinnacle with an improved version of the Mark IX that had amazing performance. It had a speed of 377 mph, which made it one of the fastest floatplanes then. Although successful, the termination of the war made this type of designs redundant and the project was eventually scrapped leaving behind an interesting what might have been history in the history of aviation.

2. Saunders-Roe SR.45 Princess -380 mph

The Saunders-Roe SR.45 Princess was a gigantic flying boat, which was ambitious on a grand scale. It was a transatlantic airliner that had been designed as a luxury but was meant to carry people across oceans in a comfortable and stylish manner.
