Radio-controlled boats are model boats controlled remotely with radio control equipment. The main types of RC boat are: scale models (12&nbsp;inches (30&nbsp;cm) – 144" (365&nbsp;cm) in size), the [[sail boat|sailing boat]] and the [[motorboat|power boat]]. The latter is the more popular amongst toy grade models. Radio controlled models were used for the children's television program ''[[Theodore Tugboat]]''.

Out of radio-controlled model boats sprang up a new hobby—gas-powered model boating.

Radio-controlled, gasoline-powered model boats first appeared in 1962 designed by engineer Tom Perzinka of Octura Models.{{citation needed|date=July 2015}} 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.

Towards the late 1960s and early 1970s another gasoline-powered model was created and powered with a similar chainsaw engine. This boat was named "The Moppie" after its full-size counterpart. Again like the White Heat, between the costs of production, engine, and radio equipment, the project failed at market and perished.

By 1970, nitro (glow ignition) power became the norm for model boating.

In 1982 Tony Castronovo, a hobbyist in Fort Lauderdale, Florida, marketed the first production gasoline string trimmer engine powered (22 cc gasoline ignition engine) radio-controlled model boat in a 44-inch vee-bottom boat. It achieved a top speed of 30 miles per hour. The boat was marketed under the trade name "Enforcer" and sold by his company Warehouse Hobbies, Inc. The following years of marketing and distribution aided the spread of gasoline-powered model boating throughout the US, Europe, Australia, and many countries around the world.

As of 2010, gasoline radio-controlled model boating has grown worldwide. The industry has spawned many manufacturers and thousands of model boaters. Today the average gasoline-powered boat can easily run at speeds over 45&nbsp;mph, with the more exotic gas boats running at speeds exceeding 90&nbsp;mph. This year also saw ML Boatworks develop laser cut wood scale hydroplane racing kits that rejuvenated a sector of the hobby that was turning to composite boats, instead of the classic art of building wood models. These kits also gave fast electric modelers a platform much needed in the hobby.

Many of Tony Castronovo's designs and innovations in gasoline model boating are the foundation upon which the industry has been built.{{citation needed|date=July 2015}} He was first to introduce surface drive on a Vee hull (propeller hub above the water line) to model boating which he named "SPD" (surface planing drive) as well as numerous products and developments relative to gasoline-powered model boating. He and his company continue to produce gasoline-powered model boats and components.
