USCG Exam PracticeRule 7 — Risk of Collision
Under the Inland Navigation Rules, which of the following correctly describes the relationship between Rule 7 (Risk of Collision) and Rule 8 (Action to Avoid Collision) when a mariner has determined that risk of collision exists?
- ✓ Once risk of collision is determined under Rule 7, Rule 8 requires that any action taken be positive, made in ample time, and with due regard to good seamanship.Correct
- B. Once risk of collision is determined under Rule 7, the vessel must immediately stop and take all way off.
- C. Rule 8 applies only after the vessels are in sight of one another as defined by Rule 11.
- D. Rule 7 supersedes Rule 8 when radar is the sole means of detection.
Why A is correct
33 CFR §83.08(a) requires that any action taken to avoid collision be positive, made in ample time, and with due regard to good seamanship. Rule 7 establishes the duty to determine risk; Rule 8 governs the character of the action once risk is identified. Rule 8 is not limited to vessels in sight of one another.
