What must the stand-on vessel do in a situation where the give-way vessel is not taking appropriate action?

In a situation where the stand-on vessel encounters a give-way vessel that is not taking appropriate action, it is important for the stand-on vessel to maintain its course and speed. This principle is based on the right-of-way rules which dictate that the stand-on vessel has the right to continue its path while the give-way vessel is expected to maneuver to avoid a collision.

By maintaining both course and speed, the stand-on vessel remains predictable in its movement, which is crucial for avoiding confusion and helping the give-way vessel understand its responsibilities. This approach allows the stand-on vessel to assert its right-of-way while still being vigilant about the give-way vessel’s actions. If the give-way vessel fails to make an adjustment, the stand-on boat can then be prepared to take evasive action if necessary, but it should primarily maintain its position until it becomes clear that the other vessel will not yield.

There are reasons why changing course and speed, stopping immediately, or accelerating would not be appropriate in this scenario. Changing course or speed could create uncertainty about the stand-on vessel's intentions, potentially leading to a collision if the give-way vessel also changes its course unpredictably. Stopping suddenly could also create a hazardous situation if another vessel is following or if the current and
