Two vessels meeting in a "head-on" situation are directed by the Rules to _____________.

In a "head-on" situation, the Rules of the Road, specifically the Navigation Rules, dictate that both vessels must alter their courses to starboard and pass each other port to port. This maneuver is established to ensure safe navigation and to avoid collisions by clearly defining where each vessel should turn.

When vessels alter course to starboard, each vessel will then proceed to their respective left side (port side) of the other vessel. This standard practice minimizes confusion and maintains predictability in their actions, promoting safety on the water. The rule is also rooted in universal maritime navigation principles that help to keep traffic flowing smoothly and safely when vessels approach each other directly from opposite directions.
