Question 38
GLI02INTERNATIONAL ONLY Two power-driven vessels are meeting. What would a two-blast whistle signal by either vessel mean?
AI Explanation
The Correct Answer is A.
A two-blast whistle signal, according to the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 34(a)(ii), signifies an executive action taken by a power-driven vessel when meeting or crossing. Specifically, **two short blasts mean "I am altering my course to port."** This signal announces the actual execution of the maneuver.
### Why Other Options Are Incorrect:
**B) "I desire to pass starboard to starboard"** is incorrect. This statement describes the desired outcome of the maneuver, but the specific signal for a port turn (which sets up a starboard-to-starboard passing) is "I am altering course to port" (two blasts). Furthermore, in a simple meeting situation, the standard passing arrangement (unless danger exists or course is altered) is port-to-port (one blast).
**C) "I desire to pass port-to-port"** is incorrect. The signal for "I am altering course to starboard" (which initiates a port-to-port passing) is one short blast.
**D) "I intend to alter course to port"** is incorrect. While the intent is certainly present, COLREGs Rule 34(a) uses executive language ("I am altering...") for meeting/crossing signals within sight of one another. The three maneuvering signals (one, two, or three blasts) announce the immediate execution of a maneuver, not just a tentative intention.
