What should the stand-on vessel do unless it becomes apparent that the give way vessel is not taking appropriate action?

The stand-on vessel is responsible for maintaining its course and speed when it has the right of way. This principle ensures that navigation is predictable and reduces the risk of collisions. The stand-on vessel should operate under the assumption that the give-way vessel will take the necessary action to avoid a collision as required by the navigational rules.

If the give-way vessel is not taking appropriate action and it becomes apparent that it may not yield, the stand-on vessel may then need to take evasive measures, potentially changing course or speed to avoid a collision. However, under normal circumstances, the stand-on vessel maintains its course and speed until it is clear that the give-way vessel will not comply with the navigational rules. This behavior ensures clarity in intentions and helps all vessels on the water understand each other's maneuvers, promoting safety and efficient navigation.
