In a scenario where both vessels are powerboats approaching head-on, what is the correct action?

In a situation where two powerboats are approaching each other head-on, the appropriate action for both vessels is to turn to starboard. This maneuver is in line with the navigational rules that dictate how vessels should react when they are on a collision course. By turning to the right (starboard), both vessels create a safe passage by altering their paths away from one another, thus effectively avoiding a collision.

This approach is based on the principle of predictable movement in maritime navigation. Turning to starboard by both vessels allows them to pass each other port side to port side, which is the established convention that further minimizes the risk of an accident and promotes safer navigation.
