Question 7 AB01 - Able Seafarer

The Correct Answer is B. **Explanation for Option B (Only when properly relieved):** The role of a lookout is critical for the safety and security of the vessel, as they are responsible for maintaining situational awareness, detecting hazards (such as other vessels, navigational markers, or dangers like ice), and reporting them immediately. Maritime regulations and the fundamental principles of seamanship (e.g., the International Regulations for Preventing Collisions at Sea, or COLREGs, Rule 5 concerning look-out) mandate continuous, effective watchkeeping. Therefore, a lookout cannot abandon their post until another qualified person has physically arrived, been briefed, and has formally taken over the duties. Being "properly relieved" ensures there is no gap in the crucial function of watchstanding. **Explanation for Incorrect Options:** * **A) 15 minutes before the end of the watch:** Leaving early, even by a short time, creates an unsupervised gap in vigilance, violating the requirement for continuous watchkeeping and potentially jeopardizing the vessel. * **C) At the end of the watch:** While the watch period ends, the *duty* of the lookout at that specific station does not end until the relieving watchstander is present and ready to assume responsibility. Leaving simply because the clock dictates the end of the watch, without relief, is negligent. * **D) At any time:** This option is fundamentally incorrect as it implies that the lookout can abandon their post arbitrarily, which is a severe breach of duty and maritime law.
