I’m a long time United States competitor in control line speed (model airplane) competition and AMA and NASS record holder (AMA Class B Electric at 142+ and NASS Sport-Jet at 165+).

Have recently learned that tether boat speeds in excess of 100 miles per hour have been recorded with steam engines. Would like to learn details of both the engine and boiler design of these boats. Where can I start?

I’m a retired aerospace engineer and friend and competitor of your Jet airplane record holder Richard Hart.
