Kay was the second competitor off the dock in the final and showed a flowing run with hits on the obstacles mixed with his technical flat water riding.
Even though Kay performed many air tricks, which are rated as very difficult and impressed competitors on site, the scoring system favours tricks performed on the obstacles higher than those performed off the flat water. Kay's impressive run, therefore, was only enough to get him onto the podium.
He said he was disappointed not to have been able to include his best tricks, but was happy with the flow of his run.
Eighteen months ago Kay took up a position with one of the largest kiteboarding brands in the world, Cabrinha Kites, based out of Hong Kong.
Kay's water park has since been picked up by Matthew Spragg, swapping his fast-paced lifestyle in Hong Kong for the kiteboarding dream in Ruakaka.
Last January, Spragg set up his own operation called Sprockett Boards and Ruakaka Kite Sports, following on from where Kay left off.
Kay was not the only Kiwi competitor at the world championships, with professional wakeboarder Brad Smeele showing his talents not only on the water, but also in the commentary box.
Smeele kept the crowds of spectators informed on the technical details of the runs performed by the professionals and amateurs - telling listeners just what tricks like "tootsie rolls", "crow mobes", "1080s" and "tantrums" are.
