Question 15 RVR03 - Mate of LT 500-1600 GRT

The Correct Answer is A **Explanation for A (A seaplane):** Rule 18(d) of the International Regulations for Preventing Collisions at Sea (COLREGs) states that a seaplane on the water shall, in general, keep clear of all vessels and avoid impeding their navigation. However, where risk of collision exists, it shall comply with the rules of the COLREGs (specifically Part B, Section II, Conduct of Vessels in Sight of One Another). Therefore, a seaplane is generally required to keep clear of a power-driven vessel and should not impede its navigation. **Explanation for other options (Incorrect):** * **B) A sailing vessel:** Under Rule 18(a)(ii), a power-driven vessel is generally required to keep clear of a sailing vessel. The power-driven vessel must not impede the navigation of the sailing vessel. * **C) A vessel not under command:** Under Rule 18(a)(i), a power-driven vessel is generally required to keep clear of a vessel not under command (NUC). The power-driven vessel must not impede the navigation of the NUC vessel. * **D) A vessel engaged in fishing:** Under Rule 18(a)(iii), a power-driven vessel is generally required to keep clear of a vessel engaged in fishing. The power-driven vessel must not impede the navigation of the fishing vessel.
