The Giroboat was the brainchild of John Hofstetter, a young UK-based American inventor, and daredevil with seemingly little consideration towards personal safety.

The “boat” part of the Giroboat was a wooden dingy with three outriggers for extra stability in case of a rougher landing, two on each side and another at the stern. On top of the boat were helicopter blades that lifted it out of the water when the towing speedboat achieved a certain speed and maintained it. The principle was the same as with an autogiro aircraft, but without an engine, since the Giroboat relied on the towing speedboat’s engine for that.

Hofstetter went public with his invention in 1960 and showed it off for the televised demo in 1961 on a lake in Glasgow, Scotland. He’d built at least two Giroboats by that point, one for himself and another for his wife Shelagh, and brought both out for the demo, which also saw Scottish speedboat champion Gordon Cameron operating one of the tow boats.

The Giroboat could be transported easily on a trailer and assembled for operation in under 5 minutes. Seeing how you only had to take out the blades and screw them onto the overhead frame, that’s not a surprise. You could then take it out on the condition that the towing boat could maintain a constant speed of 20 mph (32.2 kph) or above – any less, and the Giroboat couldn’t achieve flight.

Šķiet, pēdējās Olimpiskajās spēlēs šie vēl nebija iekļauti?
