Question 44Navigation General

The correct answer is B) red can buoy. In the IALA Buoyage System Region A (which covers the Americas, including the United States), the port side of a channel when entering from seaward is marked by a red can buoy. This follows the IALA A convention where red buoys are used to mark the port (left) side of the channel. The red can shape indicates that the buoy is meant to be passed on the port side. The other options are incorrect because black buoys mark the starboard (right) side, and conical buoys have a different shape than can buoys.
