What action should be taken when nearing a bend in a narrow channel?

When nearing a bend in a narrow channel, staying to the starboard edge of the channel while signaling with one prolonged blast is the appropriate action because it promotes safety and awareness among all vessels in the vicinity. By staying to the starboard edge, you help ensure that there is sufficient space for any oncoming vessels, particularly in channels where visibility may be limited. The prolonged blast serves as a signal to convey your intentions to other boaters, enhancing communication and reducing the risk of collisions.

This practice aligns with the navigational rules and conventions that encourage boaters to keep to the right side of the channel in situations where two vessels may encounter each other. Following this protocol maximizes safety and helps maintain an orderly flow of traffic in potentially hazardous areas. Other options may not effectively address the challenges posed by navigating around bends, such as maintaining speed or changing courses abruptly, which can lead to dangerous situations or collisions.
