Question 344 Rules of the Road

The correct answer is C) "I intend to leave you on my port side". According to the Inland Navigation Rules, one short blast from a power-driven vessel indicates that the vessel intends to pass on the other vessel's port side. In the given situation, vessel "A" is meeting vessel "B" head-on, and by sounding one short blast, vessel "A" is communicating its intention to pass vessel "B" on the port side. The other options are incorrect because: A) is for a vessel intending to pass on the starboard side, B) is for maintaining course and speed, and D) is for altering course to starboard, which is not the case here.
