Question 348Navigation General

The correct answer is A) have an even number if numbered. The U.S. Aids to Navigation System follows the rule that starboard-hand marks (those on the right side when entering from seaward) have even numbers. This helps mariners quickly identify which side of the channel they are traveling on. Options B, C, and D do not reliably indicate a starboard-hand daymark. The shape, light color, and light characteristic can vary, but the even numbering is the defining feature of a starboard-side daymark when it is numbered.
