Question 38 GLI01 - Master-Unlimited Tonnage

The Correct Answer is A. A two-blast whistle signal (two short blasts) in a meeting situation between two power-driven vessels operating under the **International Regulations for Preventing Collisions at Sea (COLREGs)** is defined by Rule 34(a)(i). This rule states that two short blasts mean: "I am altering my course to port." This signal indicates the vessel's execution of a maneuver, not just a desire or intention, making option A the accurate interpretation under the International Rules. **Why the other options are incorrect:** * **B) "I desire to pass starboard to starboard":** The signal for initiating a starboard-to-starboard passing agreement is generally one short blast ("I intend to leave you on my port side"), not two. However, the signals in Rule 34 primarily indicate the action the signaling vessel is taking, not a request for a specific passing side. * **C) "I desire to pass port-to-port":** The signal for initiating a port-to-port passing agreement is one short blast ("I intend to leave you on my starboard side"), not two. * **D) "I intend to alter course to port":** While this phrasing captures the *meaning* of the action, the specific terminology used in the International Rules (Rule 34) is "I am altering my course to port." More importantly, the use of two short blasts under International Rules signifies the **execution of the maneuver**, not just a future intention. (Note: Under Inland Rules, this signal **does** mean "I intend to alter course to port," but since the question specifies "INTERNATIONAL ONLY," the International interpretation takes precedence.)
