Radio-controlled, gasoline-powered model boats first appeared in 1962 designed by engineer Tom Perzinka of Octura Models. The gas model boats were powered with O&R (Ohlsson and Rice) small 20 cc ignition gasoline utility engines. This was a completely new concept in the early years of available radio-control systems. The boat was called the "White Heat" and was a hydro design, meaning it had more than one wetted surface.
