Question 363 Rules of the Road

The correct answer is A) one short blast. In a narrow channel, a power-driven vessel desiring to overtake another power-driven vessel on the other vessel's starboard side will sound one short blast to indicate its intention to pass on the other vessel's starboard side. This is in accordance with the Inland Navigation Rules, Rule 34(c), which states that a vessel intending to overtake another shall indicate its intention by sounding one short blast. The other answer choices are incorrect because: B) is the signal for vessels meeting head-on, C) is the signal for vessels crossing, and D) is the signal for vessels operating astern propulsion.
