Question 326Navigation General

The correct answer is B) passing daymark. Under the U.S. Aids to Navigation System on the Western Rivers, a red triangular-shaped daymark on the left bank indicates a passing daymark. Passing daymarks are used to mark the inside of bends and turns in the river, and they inform mariners of the appropriate side to pass on. Since the daymark is on the left bank, mariners should pass to the right side of the mark. The other answer choices are incorrect because: A) a special purpose signal is used for purposes other than navigation, C) a mark with no lateral significance does not indicate a specific side to pass, and D) a crossing daymark is used to mark the center of a channel, not a bend or turn.
