Question 185Navigation General

The correct answer is D) operating restrictions are in effect. A white buoy with an orange circle indicates a special purpose buoy, which is used to mark areas where specific regulations or restrictions apply. These buoys are often used to mark areas with speed limits, no-wake zones, or other operating restrictions for vessels in that area. The other answer choices are incorrect because: A) a mooring buoy is a different type of buoy, used for securing vessels; B) a white buoy with an orange diamond indicates an area where vessels are excluded; and C) a white buoy with an orange triangle indicates a danger or hazard in the water.
