<P> An airboat, also known as a fanboat, is a flat - bottomed watercraft propelled by an aircraft - type propeller and powered by either an aircraft or automotive engine . They are commonly used for fishing, bowfishing, hunting, and ecotourism . </P> <P> Airboats are a very popular means of transportation in marshy and / or shallow areas where a standard inboard or outboard engine with a submerged propeller would be impractical, most notably in the Florida Everglades but also in the Indian River Lagoon, the Kissimmee and St. Johns rivers, and the Mekong River and Delta, as well as the Louisiana bayous and Mesopotamian Marshes . </P> <P> The characteristic flat - bottomed design of the airboat, in conjunction with the fact that there are no operating parts below the waterline, allows for easy navigation through shallow swamps and marshes; in canals, rivers, and lakes; and on ice and frozen lakes . This design also makes it ideal for flood and ice rescue operations . </P>
