INLAND ONLY You are approaching a sharp bend in a river. You have sounded a prolonged blast and it has been answered by a vessel on the other side of the bend. Which statement is TRUE?

Correct Answer: Option A — If power-driven, both vessels must exchange passing signals when in sight and passing within half mile of each other.

33 CFR 83.34(e) requires that when vessels are approaching a bend where they cannot see each other, they must sound a prolonged blast. Once they come within sight of each other and are within half a mile, they must exchange the appropriate passing signals as required by Rule 34(a).
