Question 21 OSV02 - Mate - Offshore Supply Vessels

The Correct Answer is C ### Why Option C is Correct Option C, "not result in another close-quarters situation," is drawn directly from Rule 8 (Action to Avoid Collision) of the COLREGs (International Regulations for Preventing Collision at Sea), which applies to both international and inland waters. Specifically, **Rule 8(d)(ii)** states: "Action taken to avoid collision shall be such as to result in passing at a safe distance. **The effectiveness of the action shall be carefully checked until the other vessel is finally past and clear.**" Furthermore, **Rule 8(d)(i)** emphasizes that action should be "positive, made in ample time and with due regard to the observance of good seamanship." Taking action that immediately creates another close-quarters situation with a different vessel would violate the principle of taking positive, effective action that ensures passing at a safe distance and would be contrary to good seamanship. The primary goal of any maneuver is to effectively eliminate the risk of collision, not merely shift the danger to a different position or vessel. ### Why Other Options Are Incorrect **A) include a speed change** This is incorrect because while a speed change (altering course and/or speed) is often necessary and effective, the regulations do not mandate that *every* action taken to avoid collision *must* include a speed change. Often, a sufficient and unambiguous course change alone is enough to ensure a safe passing distance. Rule 8(b) simply states that if a course change is made, it should be large enough to be readily apparent. **B) be accompanied by sound signals** This is incorrect. Sound signals are required *only* under specific circumstances, mainly when vessels are approaching each other in restricted visibility (Rule 35) or when making certain maneuvers in sight of one another (Rule 34), such as altering course to port or starboard, stopping engines, or overtaking in a narrow channel. If a vessel takes timely, unambiguous action (such as a large course change) and it is clear to the other vessel, a sound signal may not be necessary under the general requirements of collision avoidance (Rule 8). The requirement is that action must be effective, not that it must always be accompanied by a sound signal. **D) All of the above** Since options A and B are incorrect, this option is also incorrect.
