Question 48 TV03 - Towing Vessels - Western Rivers

The Correct Answer is D **Explanation for Option D (at all times):** The requirement for maintaining a proper look-out is a fundamental principle of maritime safety, mandated by the International Regulations for Preventing Collisions at Sea (COLREGs), Rule 5. Rule 5 states: "Every vessel shall at all times maintain a proper look-out by sight and hearing as well as by all available means appropriate in the prevailing circumstances and conditions so as to make a full appraisal of the situation and of the risk of collision." The phrase "at all times" is explicit and absolute, applying universally to all vessels (both international and inland) regardless of time of day or weather conditions. **Why the other options are incorrect:** * **A) only at night:** This is incorrect because maintaining a look-out is equally critical during daylight hours to detect potential risks, especially in congested waters. * **B) at night and during restricted visibility:** This is incorrect because, while these conditions heighten the necessity of a rigorous look-out, the duty remains even when visibility is good and it is daytime (i.e., when neither condition applies). * **C) only during restricted visibility:** This is incorrect because a proper look-out is essential even in clear visibility to monitor traffic, navigation marks, and changes in the operational environment. Ignoring the duty in clear weather leads to complacency and is a primary cause of collisions.
