Question 898 Rules of the Road

The correct answer is D) Sound one prolonged blast. When approaching a bend in a river where you cannot see around the bend due to the bank, you should sound one prolonged blast. This is in accordance with the Inland Navigation Rules, Rule 9(e), which states that a vessel navigating with a current shall indicate her presence and her intention to pass a bend by sounding one prolonged blast. The other options are incorrect because: A) Sounding the danger signal is not the appropriate action in this situation, B) Slowing to bare steerageway may not be necessary, and C) Keeping to the starboard side alone does not sufficiently indicate your presence and intention to other vessels.
