What to do when operating in conditions of reduced visibility?
When operating in conditions of reduced visibility, you should turn on and use the navigation lights. Ensure that the light is set to the correct code and in the correct position. If radar is available, use it to make sure than you are not on a collision course with a boat without any lights.
