- A. As soon as risk of collision is first determined to exist
- B. Only after the give-way vessel has taken some action that proves insufficient
- ✓ As soon as it becomes apparent that the give-way vessel is not taking appropriate action in compliance with the RulesCorrect
- D. Only when collision cannot be avoided by the action of the give-way vessel alone
Why C is correct
33 CFR §83.17(a)(ii) states the stand-on vessel may take action to avoid collision by her maneuver alone as soon as it becomes apparent that the give-way vessel is not taking appropriate action. The obligation to act becomes mandatory only under the closer-quarters threshold described in §83.17(b).
