The MCA may exempt any ship or description of ships from all or any of the provisions of the Collision Regulations which relate to the number, position, range or arc of visibility of lights or shapes, and to the disposition and characteristics of sound-signalling appliances, if they are satisfied that compliance is either impractical or unreasonable.
