On the Wave
Taken from windsurfing, a different rule applies if you are riding waves.
The rider in the wave should always be given the right of way.
You should not interfere any wave riding session of any board sports, like windsurfing, surfing, wave kiter. They are concentrating on the wave and nothing else around, knowing they have the right of way in the wave.
Look out for someone dropping into a wave and then either let the rider pass or ride to the direction.
The one who drops in first into a wave, has the right of way as well.
