Question 356 Rules of the Road

The correct answer is C) the vessel intends to leave you on her port side. According to the Inland Navigation Rules, one short blast on the whistle indicates that the vessel is altering course to the right (starboard) and intends to leave the other vessel on its port side. This is a standard signal used to communicate the vessel's intended course of action to the other vessel, allowing them to anticipate the maneuver and respond accordingly. The other options are incorrect because: A) changing course to starboard would be indicated by two short blasts, not one; B) departing from the Rules would not be signaled by a standard whistle blast; and D) changing course to port would be indicated by three short blasts, not one.
