Question 21 ONC06 - Master LT 100 GRT

The Correct Answer is C 1. **Why option C ("not result in another close-quarters situation") is correct:** This is a direct requirement mandated by both the International Regulations for Preventing Collisions at Sea (COLREGs) Rule 8(b) and the Inland Rules equivalent. 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. **Avoidance of a close-quarters situation should be the aim, and if necessary, vessels should slacken speed or take all way off.**" The action taken must be effective and specifically must not trade one risky situation for another. 2. **Why the other options are incorrect:** * **A) include a speed change:** This is incorrect because sufficient sea room often allows for an effective avoidance maneuver (such as a large course change) without requiring a speed change. While a speed reduction or stoppage is often the safest choice (and required if doubt exists), it is not a mandatory component of *every* action taken to avoid collision. The rules allow for alteration of course and/or speed. * **B) be accompanied by sound signals:** This is incorrect. Sound signals are required only when certain specific maneuvers are performed (e.g., changing course to port or starboard, or when operating in restricted visibility). A vessel making a minor course or speed adjustment in clear sight of another vessel and maintaining its role (e.g., stand-on vessel) may not be required to sound any signal, provided the action taken is obvious and effective. Rule 34 outlines when maneuvering and warning signals *must* be used, and it does not cover *every* required avoidance action. * **D) All of the above:** Since options A and B are incorrect, this option is incorrect.
