If a stand-on vessel must take action to avoid collision, what should she avoid doing?

The situation at hand involves a stand-on vessel, which is generally required to maintain its course and speed while the give-way vessel takes action to avoid a collision. However, if the stand-on vessel finds it necessary to take action to avoid a collision, it must do so in a manner that is prudent and does not increase the risk of an accident.

Turning to port for a vessel on her own port side can create a dangerously unpredictable situation. If the stand-on vessel turns to port while another vessel is on its port side, it may not only put itself in jeopardy but could also confuse the give-way vessel about its intentions, potentially leading to a collision. In navigating these situations, maintaining clear and predictable movements is crucial for safety.

This course of action diverges from other options, where options like slowing down or reversing engines could still be considered safe if done with caution. Turning to starboard, though often discouraged in certain scenarios, might be a safer course compared to the risks associated with turning to port in this context. Therefore, it is vital for a stand-on vessel to avoid complicating maneuvers that might increase the risk, particularly when another vessel is closely following on its port side.
