Question 237Navigation General

The correct answer is A) vessels are excluded from the area. A white buoy with an orange cross within a diamond indicates an exclusion area, where vessels are prohibited from entering or operating. This type of buoy is used to mark off areas where vessels are not allowed, such as around military installations, submerged hazards, or environmentally sensitive zones. The other answer choices are incorrect because: B) an anchorage area is typically marked with a different buoy color and shape, C) a danger buoy is typically red, and D) operating restrictions are usually indicated by a different type of regulatory buoy.
