"A record-breaking 131 athletes from varying backgrounds, religions, races, and social classes united to celebrate a sport that has changed all of the competitors' lives for the better. 

"By spreading the innate stoke and joy of surfing, we strive to continue making the world a better place through surfing. 

"What we witnessed this week is a testament to the fact that the sport of Para-surfing is on the rise around the globe.

"I would like to send my sincere thanks to all competitors for putting in the hard work to come here and represent your nation. 

"It is through this community that our ambassadors strengthen our message and movement around the globe."
