Question 283Navigation General

The correct answer is A) Preferred channel buoy. Preferred channel buoys are not numbered, as they indicate the preferred navigation channel between two bodies of water. They have a red and white vertical striped pattern, and can be either conical or cylindrical in shape. The other options (B, C, and D) are all numbered buoys that indicate the lateral markers of a channel, with red buoys on the starboard side and green buoys on the port side. Therefore, the preferred channel buoy is the only one that is not numbered among the given options.
