a wave hits it
When two power driven vessels are meeting or crossing, the vessel that is to the starboard (right) is the stand on vessel. The stand-on (privileged) is to maintain course and speed. Please refer to the link below on the "Stand on" vessel.
When two motor vessels are on a collision course, the vessel that has the other on its starboard side must give way. Motor driven vessels must also give way to vessels under sail unless constrained by draft in a narrow channel.
Maintain course and speed.

The craft on the right is the "stand on" vessel, the one with the right of way, he must remain on course at speed and be prepared to avoid collision if the "make way vessel" (to port side) makes no effort to avoid or change course or speed. Avoid collisions if you are able, do not assume the operator of the other vessel sees you or knows the "aids to navigation." Exceptions to these rules, powered vessels must give way to sail and oared vessels, and less maneuverable or towed vessels, regardless of orientation.
The operator of a stand-on vessel should maintain course and speed, allowing the give-way vessel to take necessary action to avoid a collision. They should be prepared to alter course if the give-way vessel does not take action or if a collision becomes imminent. It is important for the stand-on vessel to stay vigilant and be ready to communicate with the give-way vessel if necessary.
