Question 363Navigation General

The correct answer is B. The shape in illustration D045NG that represents a daymark warning of danger is a triangle. Daymarks are visual aids used to mark navigational hazards and channel edges. According to the United States Coast Guard regulations, a triangle daymark is used to indicate a navigational hazard or area to be avoided. The other shapes in the illustration (A, C, and D) represent different types of daymarks, such as a square for a channel edge or a diamond for a safe water mark, but do not specifically indicate a danger area.
