Abstract
An amphibious vehicle having a hull and pair of multiple-flighted outriggers which coact to stabilize and propel the vehicle over land and water. The speed and direction of the vehicle is controlled by a joystick allowing an operator to move the craft over land and water with a single hand. The multiple flighting and positioning of the outriggers adds efficiency and stability to the vehicle while the joystick control adds ease of operation.
