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

The stand-on vessel is obligated to maintain its course and speed unless it becomes clear that a collision cannot be avoided. If the stand-on vessel must take action to avoid a collision, it is important to consider the behavior of the give-way vessel and the safest course of action to ensure mutual safety.

Turning to the right is often preferred because it allows for a predictable maneuver in maritime navigation. In many cases, vessels operating under the COLREGs will instinctively steer to the right, as most vessels are designed to turn this way more smoothly. This maneuver also helps maintain clarity of intentions to other vessels in the area, as it is a common practice.

In contrast, if the stand-on vessel turns to the left, it may increase confusion or the risk of collision, particularly if the give-way vessel also turns left, potentially leading to a closer encounter rather than a safe passage. Thus, choosing to turn to the right in this situation aligns with the standard navigational practices to avoid misunderstanding at sea.

While considerations such as prevailing currents might affect the overall maneuverability of the vessel, the primary decision to turn in the direction of the right, away from the give-way vessel, ensures that the stand-on vessel is following best practices for collision avoidance under the
