Abstract
An oil fence having a directional control device consisting of rudder plates or wind receiver plates secured to vertical plates or skirts of the fence at an angle thereto, which are subjected to a force due to relative movement of water or wind to cause the fence to position at an angle relative to the direction of the movement of the water or wind, whereby when the oil fence is being tugged by a towing boat the oil fence line is positioned at an angle without being subjected to any bending moment or any other undue force so as to collect or recover pollutants, e.g., spilt oil effectively from water surface.
