Rider i is riding a wave down the line and going downwind as a result .Rider 2 is well downwind at first and is riding upwind and is on the following wave . Rider 1 realises that rider 2 is on the folowing wave riding upwind and does not appear to have any intention of turning and riding down the line on that wave and rider 1 also recognises that rider 2 's kite is out over rider ones wave.Rider 2 has seen kiter on wave in front going down the line .It is too late for rider 1 to bail out and head to sea and is forced to ride straight at kite and shore to avoid collision and loses power and is swamped by wave and forced onto beach .rider 2 is either oblivious to what has happened or does not care ,this happens a second time .Would it be ok for rider 1 to be annoyed?
i'd be annoyed. the rider going upwind (why would you anyway?) has more options to change direction without the kite falling out of the sky. the person riding down the line has less room to move.
Whether you are wave riding or not, you can't just kite downwind into someone and expect them to simply get out of your way, if you are upwind you are effectively kiting towards their back/blind side, they may just be out having fun with little knowledge of wave riding. I always stay well clear of everyone and pick a wave with plenty of room downwind. Rider 1 should be annoyed with him/herself for being so dumb to select a wave with someone downwind in his/her path twice in a row, it's a big ocean out there......
^^^Paul nailed it!!^^^
Couldn't have said it betterer.
Punch up on the beach is the way to solve this.
No point staying annoyed.
I think when riding waves the law of the waves should take over from the law of sail. Give right of way to the rider closest to the breaking wave.
sounds like annoying conditions to start with
Try cross shore winds and long period swell and it wouldn't be a problem
You don't need permission to be annoyed.
As a grom growing up in the late 70's early 80's I learnt that you don't get in the way of a rider on a wave. Even if it means you paddle to the foam and get worked. It makes sense to me. We can't change the position of the wave and if the rider can't be in the sweet spot of the wave because he is dodging traffic, what's the point.
I believe this should translate to kiting.
However, times are different, there are no more groms, no learning or respect (which was mostly born of fear of said bashing).
As you point out Float, the cotton wool generation, if they can be bothered to turn up at all, turn up with all the new gear and an 'access all areas' attitude.
Maybe get really annoyed, crash your kite into his which will precipitate a confrontation on the beach.
This will get it out of your system, and induce the respect/fear in him so at least it won't happen to you again.
alls good no need for violence, i'm pretty sure i can outrun you anyway 
I reckon it's pretty basic.....
Those coming into shore give way to those leaving the beach, once both kiters are on the water standard sail craft rules apply.
Port / Starboard /Windward / leeward etc etc....
You are kite boarding ...not surfing!
Even if you have right-of-way, it is your duty to avoid a collision, once it becomes apparent that the other boat/kite is not giving way
That's not to say you can't be annoyed with the bloke, it's just that technically he may have been in the right.
Although....
If you were heading in opposite directions one of you was on a starboard tack and had right of way..... At a guess being in NSW I'd say it was a SE wind... Assuming that.....the rider going downwind on the wave should have been on the starboard tack therefore having right of way.
