The only two I know are kiter going out has right of way (which doesn't make sense if you're on a port tack while doing so), and don't jump if someone is down wind of you.
Rider going out only applicable close to shore and really only when the person is getting in the water, prepping for water start etc etc. Once they are up and moving, 25 - 50 m out from shore, normal port/starboard rule applies.
So you know the port/starboard rule that's sweet. But did you know being on starboard requires you to hold a steady course when someone is heading towards you on port? You can't keep changing course dramatically making it difficult to for the person on port to avoid you.
Other rules:
The faster rider must give way to the slower rider.
Hard object/ buoy/ land room: If someone is below you don't go downwind and drive them onto the shore. In addition to this if you are following someone into shore - don't ride up their backside so they have nowhere to turn. This overrides a port/starboard rule
When changing direction in open water check along your wake to make sure someone isn't following you and signal if you intend to change direction.
Moving gives way to stationary - obviously, someone sitting in the water putting their board on has no way of avoiding you so don't ride right up to them. (Common sense addition- keep out of the way of someone body dragging back to their board)
But also when doing a water start make sure you have the space to dive your kite and get going. If someone is passing downwind of you wait until they are past. (not a rule as such but common sense)
I sent him the money the next day and all good.
