USCG Exam Practice · Rule 17 — Action by Stand-on Vessel
A stand-on vessel in a crossing situation observes that the give-way vessel is not taking appropriate action. Under 33 CFR §83.17, what action may the stand-on vessel take at that point?
- AShe must immediately stop her engines and take all way off
- BShe may take action to avoid collision by her maneuver alone✓ correct
- CShe must alter course to starboard only
- DShe must wait until collision is inevitable before maneuvering
Why B is correct
33 CFR §83.17(a)(ii) permits the stand-on vessel to take action to avoid collision by her own maneuver alone as soon as it becomes apparent that the give-way vessel is not taking appropriate action. This is a permissive authority, not a mandatory immediate stop.
