If a sailboat overtakes a powerboat what vessel is the stand on vessel?

In the scenario where a sailboat overtakes a powerboat, the powerboat is considered the stand-on vessel. According to the International Regulations for Preventing Collisions at Sea (COLREGs), the stand-on vessel is the one that maintains its course and speed, while the give-way vessel must take action to avoid a collision. Since the sailboat is overtaking, it is the give-way vessel in this situation.
