An air boat with retractable wheels is provided. The wheels are moved from the first position to the second position by a hydraulic system. The hydraulic system is actuated by the air boat user. The first wheel position is retracted, giving continuity to the hull, permitting the fan to drive the air boat over water. The second position is extended, bringing the wheels into contact with the ground, and permitting the fan to drive the air boat over the terrain of the land. The two wheels are in parallel relation with each other and are located in and under the hull of the boat at about the middle section of the air boat. The wheels, when in extended position, only breach the hull by a small amount as there is no propeller or rudder to clear when traveling over the land. The fan provides enough lift to prevent the bow and stern from coacting with the ground.
