BOTH INTERNATIONAL & INLAND Two vessels are meeting head-on. How must the vessels pass?

Correct Answer: Option D — Both vessels should alter course to starboard and pass port to port.

Rule 14 mandates that when two power-driven vessels are meeting on reciprocal or nearly reciprocal courses involving risk of collision, each shall alter her course to starboard so that each shall pass on the port side of the other. This ensures a predictable, standardized passing maneuver for both vessels.
