In a crossing situation what vessel is required to maintain its speed?

In a crossing situation, the vessel that is required to maintain its speed is the stand-on vessel. This is the vessel that has the right of way and is expected to keep its course and speed, while the give-way vessel must take action to avoid a collision by altering its course or speed. The stand-on vessel should be prepared to take evasive action if it becomes apparent that the give-way vessel is not taking the necessary steps to avoid a collision.
