What defines the propulsion type "Air Thrust" in watercraft?

Air Thrust in watercraft refers to a propulsion type that utilizes an engine typically found in aircraft or automotive settings. This type of propulsion works by creating thrust through the expulsion of air, allowing the watercraft to achieve movement over the water surface.

Using engines designed for air travel or automobiles can provide higher RPMs and the ability to operate in a more efficient manner in certain water conditions compared to traditional marine engines. Therefore, the propulsion system is characterized by these unique features and mechanics, making it distinct from other types of propulsion used in watercraft.

In comparison, traditional motor use, high-speed propeller mechanisms, and water screws represent different forms of propulsion systems designed specifically for marine applications and do not utilize the specialized air-focused mechanics that characterize Air Thrust systems.
