If the stand-on vessel must change course to avoid collision, in which direction should she turn?

Answer: B — To the right

The stand-on vessel is defined by the COLREGs as the vessel that has the right of way in a crossing situation but is still obligated to take action if a collision is imminent. If the stand-on vessel must change course to avoid a collision, she should generally turn to the right. This practice helps ensure clear signaling and understanding of intentions between vessels in close proximity, as turning to the right is a standard maneuver that allows other vessels, especially the give-way vessel, to anticipate movements. In maritime navigation, turning to the right (starboard) is often the preferred action as it aligns with the typical direction of traffic flow and maintains the predictability of maneuvers. Additionally, turning to the right maintains the stand-on vessel's position relative to her original course, which aids in communication of her intentions. This is particularly important in congested waterways where predictable behavior is crucial for safety. The other options include considerations that may complicate a situation unnecessarily. For example, changing course based on prevailing currents introduces factors that could result in unpredictable or dangerous situations. Similarly, turning in the opposite direction of the give-way vessel could lead to misunderstandings and increase the risks of a collision, as it may not align with the standard navigation practices that prioritize predictability
