Question 30

The Correct Answer is B **Explanation for Option B (Correct Answer):** The standardized whistle signal for "Stop lowering" (or "Hold") during boat or lifeboat operations (such as drills or deployment) is **2 short blasts of the whistle**. This signal is internationally recognized in maritime operations, particularly concerning Safety of Life at Sea (SOLAS) regulations and typical shipboard emergency procedures, ensuring clear and immediate action is taken by the davit operator or crew controlling the falls. **Explanation of Incorrect Options:** * **A) 1 short blast of the whistle:** This signal typically means "Lower" or "Start lowering" the boat, initiating the descent procedure. * **C) 3 short blasts of the whistle:** This signal commonly means "Heave up" or "Hoist" the boat, reversing the lowering process. * **D) Continuous blast of the whistle for not less than 3 seconds:** A continuous or prolonged blast is usually reserved for general emergency signals, such as the general alarm, or potentially as a distress or maneuvering signal, but it is not the standard operational signal for "Stop lowering" during routine boat work.
