A propeller driven vehicle, such as an air cushion hovercraft, comprising a hull, a teardrop shaped cabin mounted on the hull and a propeller arranged in front of the cabin. A gutter shaped obstructing plate is pivotally mounted to each side wall of the cabin and is movable between a horizontal and vertical position. When the obstructing plate is moved from its horizontal position to obstruct the air flow from the propeller around the side wall of the cabin, a pressure differential is created on the cabin which is effective in steering the vehicle.
