BOTH INTERNATIONAL & INLAND In which situation do the Rules require both vessels to change course?

Correct Answer: Option A — Two power-driven vessels meeting head-on

Rule 14(a) mandates that when two power-driven vessels are meeting on reciprocal or nearly reciprocal courses so as to involve risk of collision, each shall alter her course to starboard so that each shall pass on the port side of the other. Both vessels must take this specific action.
