Airboat

Airboat is a flat-bottomed vessel propelled in a forward direction by an aircraft-type propeller and powered by either an aircraft or automotive engine. They are commonly used for fishing, bowfishing, hunting, and ecotourism.
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, for example, in the Florida Everglades, parts of the Indian River Lagoon, the Kissimmee and St. Johns Rivers, as well as Louisiana Bayous.
