As you enter a channel from its downstream end, what happens to the numbers on the starboard side buoys?

As you enter a channel from its downstream end, the buoys on the starboard side will increase in number and be red in color. The color coding system for buoys helps with navigation and maintaining a safe course through channels.

In the United States, the IALA (International Association of Lighthouse Authorities) system is followed, where red buoys are placed on the right side of the channel when entering from the downstream end. These red buoys are numbered sequentially, which means they will increase as you move upstream. This system promotes consistency and aids in navigation, helping boat operators to determine their position and direction accurately.

The relationship between buoy colors and numbers allows operators to understand their location in relation to the channel's safe navigable waters, reinforcing safe passage and reducing the risk of accidents.
