Question 44 UFV01 - Master - Uninspected Fishing Vessels

The Correct Answer is D **Explanation for Option D (Correct Answer):** According to both the International Regulations for Preventing Collisions at Sea (COLREGs) (Rule 34(a)(iii)) and the Inland Rules (33 CFR § 83.34(a)(1)(iii)), when power-driven vessels are in sight of one another, a maneuvering and warning signal consisting of **three short blasts** on the whistle means: "**My engines are operating astern**." This signal indicates that the vessel is using its engines to back up or stop its forward motion, typically used when maneuvering in close quarters or backing out of a slip. Therefore, vessel "A" is backing engines. **Explanation for Incorrect Options:** * **A) Vessel "A" intends to hold course and speed:** This intention is not communicated by a whistle signal. If Vessel A were the stand-on vessel and taking no action, it would typically not sound any maneuvering signal (unless giving warning, etc.). Maneuvering signals indicate a change in action or direction. * **B) Vessel "A" is sounding a signal of doubt:** A signal of doubt or disagreement (the "danger signal") consists of **five or more short blasts**. Three short blasts have a specific, different meaning (backing engines). * **C) Vessel "A" proposes to cross ahead of the other vessel:** A proposal for a passing or crossing action is indicated by different signals. In International Rules, this is often indicated by two short blasts (I intend to leave you on my port side). In Inland Rules, this would typically involve one short blast (I intend to leave you on my port side) or two short blasts (I intend to leave you on my starboard side), often accompanied by reaching agreement. Three short blasts specifically means backing engines.
