I don't know anything about Phuket just that the hotel I stayed at the wave took it ,but the best way to advance is to have your own gear ,I agree with the SCB suggestion s on gear .sizes .If you can find a 7.0 Ezzy Chetah they are more robust and won't get damaged as much when you fall .
looking forward to the next test vid .👍I can kinda see how it works from my sailing days ,where the catamaran hauls where generally faster as there was no big platform hitting the water .very interesting 👍
