Notice that on the video made by the urbnsurf guy in Melbourne, he talks about the modular technology and pistons pushing water to form waves without turbulence behind it.
It is clear that this tech is a superior form of producing quality waves (for a few reasons) compared to the old wavegarden tech which is almost exactly the same as Kelly's pool.
This is the video of the Melbourne guy explaining the cove technology from inside their pool just about to be filled
This is the video of the technology developed in the UK probably behind the Wavegarden Cove model.
This is very interesting and to fully understand it I recommend you watching the 3 parts and other videos on their channel:
The future looks fun as fark!
Part 2 -
Part 3 -
It's on part 3 where you can see the whole picture, with the exact shape of the Cove.
