Question 84 Rules of the Road

The correct answer is C) 2 short blasts. According to the Navigation Rules and Regulations, when a power-driven vessel intends to overtake another power-driven vessel on the overtaken vessel's port side, the overtaking vessel should sound two short blasts to indicate its intention. This signal informs the vessel being overtaken that the overtaking vessel wishes to pass on the port side. The other options are incorrect because: A) 2 prolonged and 1 short blasts is the signal for vessels crossing, B) 2 prolonged and 2 short blasts is the signal for vessels meeting head-on, and D) 1 short blast is the signal for vessels passing on the starboard side.
