Is a motor boat or pwc the stand on boat?

In a situation where a motorboat and a personal watercraft (PWC) are approaching each other, the motorboat is generally considered the stand-on vessel, while the PWC is the give-way vessel. This is because motorboats typically have more maneuverability and are subject to different navigation rules. However, specific circumstances and local regulations can affect this designation, so it's always essential to be aware of the rules of the waterway in which you are operating.
