ABSTRACT:
An air boat having a monocoque design is described. The deck and hull are rigidly reinforced with a plurality of formed channels that run parallel along the deck. Side ribs that are disposed perpendicular to the channels provide stiffness in the intersecting plane of the hull. Water-flow channels defined by elongated ribs run along the bottom of the hull and compress water and provide lift to the boat, reducing sideways slippage and spray of the craft during maneuvers and turns. The steering mechanism includes dual fins and a no-feedback gearbox that resists self-straightening when the pilot releases the steering wheel. The turning radius of the boat is especially short. A safety cage is foldable and encloses a motor, the motor mount of which uses the boat hull as its base structural element.
