Had a pretty heated exchange at my local a coupe of years back, on a normal day it's pretty average and I'm no wave purist, but we always give way to whoever is on the wave, if you've worked your way onto it we just bear downwind and make our way out the back, nothing gives me the ****s more than some one coming across your path as they carnt be arse making their way upwing to the wave, just spoke with a mate on his return from gnarloo who said it was a **** fight
Be aware that windsurfers have different right of way rules they follow in waves... the guy going out has right of way, the sailor on the wave needs to keep clear.
Once out back, normal port and starboard rules apply.
This is down to the fact that windsurfers usually have less speed (marginal planing) and manoeuvrability when going out through the surf.
In the situations where kites and windsurfers are in the waves together it's best if everyone plays nicely together - everyone tries to ensure that the guy on the wave has a clear run at it, but you might need to go around a windsurfer coming out.
