Question 21 OSV01 - Master/Chief 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(d) of both the International Regulations for Preventing Collisions at Sea (COLREGs) and the Inland Rules. Rule 8 (Action to Avoid Collision) mandates that any action taken to avoid collision must be “positive, made in ample time and with due regard to the observance of good seamanship.” Specifically, Rule 8(d) 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."** The interpretation and application of this rule mean that the maneuver must resolve the immediate danger without creating a new, subsequent risk of collision or forcing the vessel into another close-quarters situation with the same or another vessel. This is a fundamental requirement for successful collision avoidance. ### Why Other Options Are Incorrect **A) include a speed change** This is incorrect because a speed change is only one method of collision avoidance, and it is not always mandatory or the preferred method. Rule 8(b) states that "Any alteration of course and/or speed to avoid collision shall, if the circumstances of the case admit, be large enough to be readily apparent to another vessel..." While a speed change (like slackening speed, stopping, or reversing) is a valid action under Rule 8(e), many situations only require a course alteration (Rule 8(c)) to pass clear, making a speed change optional, not mandatory. **B) be accompanied by sound signals** This is incorrect. Sound signals (Rules 34 and 35) are required when a vessel changes course or speed *and* that maneuver is required by the Rules (e.g., meeting in a narrow channel, overtaking, or crossing situations) or when restricted in visibility. However, many actions taken to avoid collision in clear visibility (such as a slight course alteration when crossing well ahead) do not legally require a sound signal. Sound signals are required to communicate intent, but the action itself is not universally mandated to be accompanied by a sound signal. **D) All of the above** Since options A and B are incorrect, this option must also be incorrect.
