Maintain course and speed.
The vessel being "overtaken" is the stand-on vessel. The vessel "overtaking" is the give-way vessel.
When a sailing vessel and a pwc are meeting head on the sailing vessel is the stand on vessel.
Powerboat
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.
When a sailboat overtakes a powerboat, the powerboat is the stand-on vessel. (Ref: SB-29)

If you are operating a motorboat and your motorboat is being overtaken by a sailboat, you should maintain present course and speed. The vessel that is overtaking another vessel is the give-way vessel, regardless of whether it is a sailing vessel or a power-driven vessel. The vessel being overtaken is always the stand-on vessel.
If they are BOTH power driven vessels, the vessel to "right" (Starboard) would be the "stand on" vessel, maintaining course and speed. The Vessel on the "left" (Port) is the "give way" vessel and will have to (if) possible avoid crossing in front of the stand on vessel. Please refer to the link below. Rule 15
