Where are green buoys located when entering a channel from the open sea?

The correct answer is that green buoys are located on the left side of the boat when entering a channel from the open sea. This aligns with the IALA buoyage system, which is commonly used in the United States, including Missouri.

According to this system, when navigating from the open sea into a channel, you must keep green buoys (which indicate the left side of the channel) on your left. This helps boaters understand which side of the channel they are navigating. The purpose of this system is to promote safe navigation and to help boaters avoid hazards that may exist on the right side of the channel.

Understanding the buoy colors and their meanings is crucial for safe boating, as it ensures that you navigate the waterways correctly and avoid potential collisions or groundings. Other options don't accurately describe the proper placement of the green buoys in relation to the channel and the vessel's course.
