Question 127 Rules of the Road

The correct answer is D) intends to leave the other on her port side. In an inland crossing situation, the stand-on vessel (the vessel that has the right-of-way) is required to sound one short blast of the whistle to indicate that it intends to hold course and speed, allowing the give-way vessel to pass on its port side. This is in accordance with the Inland Navigation Rules, which govern vessel operations on inland waterways. The other options are incorrect because A) would indicate the stand-on vessel is changing course to starboard, which is the opposite of the intended action, and B) and C) do not accurately reflect the meaning of the one short blast signal in an inland crossing situation.
