Question 195Navigation General

The correct answer is B) horizontal bands. Under the IALA-A Buoyage System, a buoy indicating the preferred channel to port (left) would have horizontal bands. This is because buoys marking the preferred channel are known as "lateral marks," and lateral marks have horizontal bands to denote the side of the channel. The other answer choices are incorrect because: A) a pillar shape is not a characteristic of a preferred channel buoy, C) an even number of bands is not used, and D) an odd number of bands is also not a characteristic of a preferred channel buoy.
