Question 21 GLI03 - Master-LT 500-1600 GRT

The Correct Answer is C ### Explanation for Option C (Correct) Option C is correct because it directly reflects a fundamental requirement found in Rule 8(c) (Action to Avoid Collision) of the International Regulations for Preventing Collisions at Sea (COLREGs) and Inland Rules. Rule 8(c) states that if there is sufficient sea room, a course change alone may be the most effective action, provided that it: 1. Is substantial (readily apparent to the other vessel). 2. **Does not result in another close-quarters situation.** The primary goal of any avoidance maneuver is to eliminate the risk of collision without immediately creating a new, dangerous situation with the same or another vessel. If an action results in another close-quarters situation, the action taken was insufficient or improper. *** ### Explanation of Why Other Options Are Incorrect **A) include a speed change** This is incorrect. Rule 8(b) specifies that action includes "alteration of course **and/or** speed." The regulations emphasize that course changes alone (when substantial) are often the most effective action if sufficient sea room exists (Rule 8(c)). There is no requirement that every action must include a speed change. **B) be accompanied by sound signals** This is incorrect. While certain actions (such as altering course to port or starboard when vessels are in sight of one another) require corresponding sound signals (Rule 34), not *every* action taken to avoid collision mandates a sound signal. For example, a minor reduction in speed (if deemed appropriate avoidance action) or an early, substantial course change taken far in advance of risk may not require an immediate sound signal under the standard maneuvering rules. The requirement is that the action be "readily apparent," which is often accomplished visually, not necessarily acoustically. **D) All of the above** Since options A and B are not universally required by the rules, option D is incorrect.
