What should you do if another vessel approaches head-on?

When another vessel approaches head-on, the appropriate action is to alter your course to the right. This maneuver aligns with the navigation rules that dictate how vessels should interact in close proximity. By steering to the right, or starboard side, both vessels can avoid a potential collision, as this is the conventionally accepted practice in boating to give way.

The rationale behind this rule is to ensure a clear passage and to minimize confusion about intentions. Boats turning to the left may potentially lead to a collision course if both vessels did so simultaneously. Comments like signaling to change course or speeding up can lead to misunderstandings or further complications. Therefore, steering to the right ensures that both vessels have a clear path and enhances safety on the water.
