Abstract
A hovercraft is described having a fan mounted to rotate about a vertical axis. The airflow from the fan is directed to the skirt to create lift and to horizontally aligned outlets to positively propel the craft in both forward and reverse directions and, if necessary, provide a braking force. A valve arrangement is provided to alter the relative airflow between the different horizontally aligned outlets.
