Disclosed is a hovercraft having a pair of air cushions, associated with each air cushion is a rotatable fan which partly produces lifting force and partly propels and maneuvers the craft. The fans are mounted perpendicular to the direction of travel, peripherally on the craft, wherewith the forces produced have long moment arms, and consequently produce a strong turning torque. The fans are mounted on the craft in such a manner that their orientation may be adjusted both horizontally and vertically with respect thereto.
