BOTH INTERNATIONAL & INLAND When two power-driven vessels are meeting head-on and there is a risk of collision, which action is required to be taken?

Correct Answer: Option D — alter course to starboard

Rule 14(a) explicitly requires that when two power-driven vessels are meeting on 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 is the mandatory action to resolve the head-on conflict safely.
