Final answer:
When being overtaken in a narrow channel, the boat should maintain its course and speed and signal its intention to the overtaking boat. Responding properly is important for safe navigation and accident prevention.
Step-by-step explanation:
When a boat is being overtaken in a narrow channel, it is important to respond appropriately to ensure safety and avoid colliding with the overtaking boat. The boat being overtaken should maintain its course and speed to allow the overtaking boat to safely pass. It is also advisable for the boat being overtaken to signal its intention to the overtaking boat by using appropriate sound signals or visual signals.
For example, if a boat is being overtaken from behind in a narrow channel, the boat should continue moving in a straight line and refrain from making any sudden changes in course or speed. The boat may use a sound signal such as one prolonged blast followed by two short blasts to indicate that it is being overtaken and that the overtaking boat should pass on its port side.
Responding properly to being overtaken in a narrow channel is essential to maintaining safe navigation and preventing accidents. By following established navigational rules and effective communication, both boats can navigate the narrow channel safely.
