The invention discloses an air boat which comprises a hull.An upper loading support is arranged in a cabin of the hull.A power device is installed on the upper loading support.A deck of the hull bends forward and is in a shape that the front is low and the rear is high.The power device is located at the one-third position of the rear portion of the hull.After the hull is in water, the deck is in a horizontal state naturally, and the axis of a rotating shaft of the power device is parallel to the plane of the hull bottom.Supra polymer PE plates are attached to the hull bottom and the two sides of the hull.The supra polymer PE plates and the hull are fixedly connected through countersunk head self-tapping screws and sealant.Power performance of the air boat is improved, the bearing ability of the hull is improved, and advancing resistance of the hull in the complex environment is reduced.
