What, Who and Where  

What is tethered hydroplane racing

Modern tethered hydroplane racing offers competitors a variety of classes and options with which to pit their skills against the clock. The tethered hydroplane is a purpose built model, designed expressly for high speed on water using either an immersed propeller or airscrew. Boats are connected via a pair of wire bridles and a line of set length to a rotating pylon. This will give a circular lap of known length, usually 100 yards or 100 metres. There is no steering or any other means of control. The boat, be it a flash steamer, novice or vintage, powered by a large capacity home-built engine, a high performance commercial two-stroke, or even an electric motor is connected to the line and the engine started. When satisfied that the engine is producing maximum power, the competitor launches the boat off on its run, aided by a rubber bungee. The timed laps are signalled by the competitor when happy that the boat is at its fastest. The elapsed time for the required number of laps is translated into speed and the head scratching starts over adjustments needed to achieve an even faster run next time. This is the quest that has continued to challenge participants in this fascinating sport of tethered hydroplane racing for over 100 years.
