What daymark shape is used in the lateral system?
AI Explanation
The correct answer is B) Triangle.
In the lateral system used in the United States, the daymark shape for lateral aids to navigation is a triangle. This is specified in the United States Aids to Navigation System, which is the regulatory standard that governs the design and use of navigation aids. The triangle shape is used to indicate the left or port side of a channel when traveling upstream or entering from seaward.
The other answer choices are incorrect because diamond shapes are used for preferred channel marks, pentagons are used for special purpose marks, and semicircles are not a standard daymark shape in the US lateral system.
