BOTH INTERNATIONAL & INLAND Your vessel is underway in reduced visibility. You hear the fog signal of another vessel about 30° on your starboard bow. If danger of collision exists, which action(s) are you required to take?
Official USCG Answer & Rule Citation
Correct Answer: Option C — reduce your speed to bare steerageway
Rule 19(e) requires that if you hear a fog signal forward of your beam and cannot avoid a close-quarters situation, you must reduce speed to bare steerageway. This ensures maximum time for assessment and maneuverability while minimizing the kinetic energy involved in a potential collision.
