In head-on scenarios with watercraft, what must a pilot-in-command do?

In head-on scenarios with watercraft, the general convention is that both vessels should alter their course to the right. This practice is part of the "Rules of the Road" which help to ensure safety and prevent collisions on the water. The rationale behind this rule is to establish a clear and consistent procedure for navigating encounters between vessels, which minimizes confusion and promotes safe passage.

Changing direction to the right is what is typically referred to as "starboard" and is designed to create a wider passage between the vessels, as both will turn in the same direction. This reduces the risk of collision by allowing both vessels to maintain their course without overlapping paths dangerously.

While other options such as changing direction to the left, continuing on the current course, or just slowing down may seem reasonable at first glance, they do not align with the established maritime navigation rules. For instance, continuing on the current course could result in a collision, and changing direction to the left could lead to a dangerous situation with potential encounters from both vessels rather than preventing it.
