An airboat is a type of watercraft that is propelled by an aircraft-style propeller. It is commonly used in marshlands, swamps, and other shallow bodies of water where traditional boats may become stuck in mud or grass. Synonyms for airboat include fanboat, hovercraft, swamp boat, and marsh buggy. Each of these terms describes a vehicle that utilizes an air cushion to glide over water and other surfaces. While airboat is the most commonly used term, the other synonyms are equally descriptive and evoke images of adventure and exploration in unique natural environments.
