The boat overtaking the other boat is the give way vessel.
faster boat
The boat that is doing the passing is the Give-way vessel. They must stay clear of the boat that they are passing. The boat being passed is the Stand-on vessel, they do not move or alter speed.
The overtaking vessel must always give way. Therefore the powerboat must be prepared to stop or change direction - the sailboat has right of way.
The overtaking craft should give way, as the overtaking craft should be the one with the most control, as it is initiating the move.
the PWC
The boat coming from behind has no rights. It must overtake the slower boat safely whichever side it chooses.
A sailboat under sail should never give way to a motor boat. However, if it comes up against another sail boat: 1. Overtaking boats must give way 2. Those on Starboard tack have right of way 3. The boat that is closest to the wind (or on the windward side) should give way
The boat that overtakes another boat is the give-way vessel. The boat being overtaken is the stand-on vessel. When a sailboat is the overtaking vessel, she must keep clear of the powerboat. Any vessel overtaking another must stay clear of the vessel being overtaken (Rule 13). Please refer to the Navigational rules. Specifically Rules 8, 9, 12, 13, 14, 15, 16, 17 & 18.

SB-13 in the navigation rules what must the give-way boat do?
You pass on the inside of the arena.
Both pilots should be aware of an impending collision and must take take immediate action. First things is to slow down and go towards the port (left) and see if the other craft does likewise. If they don't then you need to go towards starboard (right). Every boat pilot needs to keep their head on a swivel at all times ... they must always be aware of their surroundings at all times. That is an essential part of piloting a boat of any size. Even the huge freighters and tankers have several people on the bridge looking out for other boat traffic.
