BOTH INTERNATIONAL & INLAND You are approaching a bend in a channel. You cannot see around the bend because of the height of the bank. Which action are you required to take in accordance with the Rules?

Correct Answer: Option C — Sound a whistle blast of 4 to 6 seconds duration

Rule 34(e) mandates that a vessel nearing a bend or area where other vessels may be obscured by an intervening obstruction shall sound one prolonged blast. This signal serves as an audible warning to any vessel on the other side of the bend, alerting them to your presence and approach.
