Question 37 UFV01 - Master - Uninspected Fishing Vessels

The Correct Answer is C **Explanation for Option C (Correct Answer):** The question specifically asks about the **International** Rules of the Road (COLREGs). According to Rule 34(a)(i) of the International Regulations for Preventing Collisions at Sea: * **One short blast** signifies: "I am altering my course to **starboard**." * **Two short blasts** signify: "I am altering my course to **port**." * **Three short blasts** signify: "I am operating astern propulsion." Therefore, two short blasts indicates that the vessel is currently executing an alteration of course to port. **Why the other options are incorrect:** * **A) The vessel will alter course to port:** While the vessel is indeed altering course to port, the word "will" can imply future intent. Under International Rules, the signal signifies the *action currently being taken* ("I am altering..."), not just the intention or future action. Option C is the most precise description of the mandatory meaning of the signal under COLREGs. * **B) The vessel intends to pass starboard to starboard:** Signals related to passing or meeting arrangements (like intent to pass to starboard or port) are primarily governed by the **Inland** Rules of the Road (U.S. waters), not the International Rules. Under International Rules, these blasts are defined purely as maneuvering signals (altering course) and do not explicitly convey passing intentions unless danger necessitates the use of the danger signal (five or more short blasts). * **D) The vessel intends to alter course to port:** As noted in the explanation for A, the International signal is defined as the vessel *executing* the maneuver ("I am altering my course"), not merely intending to do so. The signal communicates the immediate action being taken.
