What action should both vessels take when meeting head-on?

When two vessels are meeting head-on, the appropriate action is for both vessels to turn to starboard, which is to their right. This action is important for ensuring safe navigation and avoiding collisions. By turning to starboard, each vessel effectively steers clear of the other, creating a safe passage. This maneuver follows the "Rule of the Road" principles, which are designed to promote safety on the water.

Maintaining speed and course would pose a significant risk of collision, especially when vessels are approaching directly toward one another. Stopping both vessels is not practical, as it could lead to confusion and does not guarantee safety. Similarly, turning to port (the left) would be incorrect in this situation, as it could lead to a direct collision when both vessels attempt to maneuver in that direction. Therefore, the correct and safest action is for both vessels to steer to starboard.
